Dedicated Servers vs Cloud Servers

A Comparison between Dedicated Servers and Cloud Servers

Is a dedicated server hosting solution the best one for you or do you believe that a cloud hosting service will help you manage your tasks better? Entrepreneurs often find it tough to make a choice to choose between dedicated servers and cloud servers. This apples-to-apples comparison between dedicated servers and cloud servers will help you decide which option you should go with for running your business operations smoothly.

Experts caution against making an impulsive decision as it can have long term effects on the future prospects of your business. It is advisable to make a decision based on your practical current and future needs. The best way to make the right choice is to understand the differences between dedicated server hosting and cloud hosting—two of the major hosting options that most organizational prefer using.

The areas that you have to focus on are budget and operational implications. If you get a clear idea on these aspects, you will be able to make the right choice pretty easily. Let us look at cloud servers first.

Cloud Servers: Scalable Flexibility—At A Premium

When you choose cloud hosting, you can enjoy the key benefit of scalable flexibility but at a price, of course. You can also save money as you are spared the cost and hassle of investing in hardware. Cloud servers are ideal for those businesses that operate best in a highly flexible environment and have high seasonal demands.

Cloud servers can be deployed quickly and easily with just a click. You can use the cloud server features to scale up key areas of operations when there is a higher demand for resources. Cloud servers can satisfy the need for enhanced computing powers even if they are needed in rapid spurts and at a short notice. This makes cloud hosting a highly portable solution that can help businesses meet their varying demands and requirements.

Cloud servers are virtualized which again works to the benefit of an organization. Your business need not be chained to any single server and its features which might not allow you to draw the computing resources you might need from time to time. With cloud servers, you can scale up as and when needed and absolutely on demand as well. The load balancing feature of cloud servers allows quick and easy distribution of workload during the most demanding times. This is achieved by tapping into the resources offered by multiple servers of the cloud.

Resilience is another key feature of cloud hosting. You can also enjoy:

– Redundant hosting
– Secure backup strategy
– High degree of restorability
– Superior operational stability

Potential cloud server users, please note that all of the above comes with a caveat. The hosting company will have a major say in choosing the servers for hosting the cloud. This can affect the list of features available to you. So make your choice after careful consideration of what the cloud hosting service providers promises to offer in the package that you plan to buy.

It must be noted that the high flexibility and comparatively lower initial investment is not as straightforward a deal as it may seem. You are billed for the resources used which means that if you do not plan your usage, you will be dealing with a hosting service that can burst your budget.

Dedicated Servers: Enjoy High Reliability And Solid Performance

Hosting experts are unanimous in their opinion that deploying a cloud server is easier than deploying a dedicated server. As dedicated servers are physical in nature, they must be procured, installed and configured within a data center. The whole process can be time-consuming and may take a few days to be completed properly.

Dedicated servers are ideal for organizations in which the IT requirements are constant and are unlikely to change in a major way over time. These servers are known for assisting high performance in critical areas of business operations.

A key benefit of using dedicated servers is that you are in control of its use. With no chance of any other unknown users occupying your server space, you can expect exceptional reliability and stability. You also have sole access to all the resources lodged in the server which can ensure uninterrupted operation of services.

Unlike cloud servers, managing dedicated servers require some extra efforts:

– You will have to hire a team of IT experts for managing operations and maintenance.
– Server experts are needed for strategizing and controlling software and security updates.
– You need a fairly decent budget for hosting, running and maintaining a good quality dedicated server.

However, the consistency, stability and predictable billing are features that make dedicated servers more attractive.

Before you go shopping for dedicated servers, it is important to identify your organization’s IT goals and future plans. Choose a hosting service that can provide you dedicated server hosting plans that are features-rich, affordable and flexible.

Most importantly, consult a server hosting consultant or expert.

How to Strike the Perfect Balance between Cloud and On-Premise IT

Cloud computing technologies are continuously evolving as more and more organizations keep embracing the cloud. Since the cloud can offer many benefits in terms of cost-savings, flexibility and scalability, businesses are keener than ever to leave behind their traditional on-site IT infrastructures and move data to the cloud.

While the cloud may have many benefits to offer it is important for organizations to find the perfect balance between on-site IT and cloud. There are companies, which are able to use cloud technologies seamlessly, but there are also some, which end up paying more to get cloud hosting solutions and the even, expose their data to risks. So, creating the ideal balance between the on-site and cloud architectures is imperative; when there is a hybrid middle path, it is possible to get the best of both worlds.

How to find the right balance between cloud and on-site IT infrastructures:

– Cloud hosting offers many benefits but one should remain realistic and find out the locations where data is getting stored. If you continue to keep unstructured cold data in clouds for a prolonged period, you may be faced with huge bills afterwards. Clients have to pay according to capacity and when the space you use increases, costs are bound to go up. So, what may have seemed to be economical at first eventually becomes expensive. The best way to resolve this issue is to eliminate the obsolete data. This will help to decrease the billing amounts. There are companies which often keep data with them for purposes of cloud backup, compliance and data mining. But, such data is best kept on-site, thereby freeing up space in the cloud.

cloud hosting

– When there is a standard migration data has to be shifted from on-site to the virtual environment. This migration typically occurs in stages, assuring an incremental upgrade which is not going to disturb operations by moving big chunks of the IT environment offline. Neither will the staff be forced to re-learn basic tasks in the quickest time possible. Companies which may have restrictions on certain types of data are still able to shift other operations to a cloud without affecting compliance. It is important to make sure that client data is kept in a secure server onsite; however, the back office data like HR or accounting resources can be conveniently shifted to a cloud. So, your company will be successful in moving legacy systems to SaaS and continue to benefit from scalability, mobility and cost-savings while satisfying client demands at the same time.

– Besides its use in compliance matters, this balance is useful even elsewhere, for instance, where municipal services are being offered. For example, Department of Transportation is able to redistribute resources to make innovations smoother by shifting the back-office operations to a cloud together with non-critical data and keeping mission-critical data on secure on-site servers.

– It is true that most cloud vendors will provide built-in security systems along with round-the-clock maintenance of virtual servers so as to avoid data loss incidents or cases of intrusion. However, there is always data present which is found to be too sensitive for cloud storage. Some businesses may also not be open to the idea of collaborating with an outsider to handle IT security concerns. Finally, there are other applications which can be better protected from hackers by storing them on-site.

– Data which must be quickly accessed should ideally not be kept in the cloud. While cloud providers will guarantee a high server uptime, chances of service disruptions cannot be ruled out. In such situations, data which has been stored on premise can always be accessed.

– When trying to find the correct balance between cloud and on-site IT set-ups it is also necessary to understand that you will still need IT personnel even when you may have shifted much of the infrastructure into a cloud. While the daily operations in the cloud may not need your constant attention, cloud hosting solutions cannot run on their own. Your IT staff will now face newer challenges and they will have to hone their skills further. They will have to learn how to use the new technologies to boost productivity and performance. So, they will need to carry out upgrades and help the team to use resources better.

– Daily functions may function through an on-site IT infrastructure but apps and data which have been stored in the cloud can give businesses the agility they need in times of disruptions and emergencies. There may be incidents of fire, floods and storms which can leave the office inaccessible. It is then that the cloud can help you recover data faster through offsite disaster recovery solutions.

– Besides costs, data threats may also appear when you use public cloud solutions. The cloud may be able to provide resilience via erasure coding technique but this is limited and will only protect data when there is hardware crash or an uncommon on-site disaster. The cloud does not have comprehensive means to protect data from human errors, ransomware, malicious attacks etc. When you are dealing with very sensitive data this may pose a problem, for instance, healthcare systems or legal firms. You will require extra protection and such data may be unfit for the cloud.

To sum up, not every legacy application is fit for integration with cloud technologies. There may however be many apps which are designed for public cloud solutions. So, you must plan migration carefully to get favorable results. That way you can also enjoy cost savings and peace of mind.

aws

Costs of AWS vs. Physical Servers

Many businesses feel that using AWS cloud solutions will be the best fit for all their infrastructural needs. The AWS is undeniably a leading cloud platform which has been widely accepted by most businesses, but the truth is that there are many more in the market which offer much cheaper solutions. Moreover, many of these affordable alternatives may actually prove to be better for certain businesses. This is true as there are many businesses that are not being able to use the AWS cloud services properly or they fail to extract the best out of AWS.

– According to studies of costs between signing up for AWS cloud solutions as against standard servers it is seen that the AWS on-demand instances have been almost 300% costlier than if businesses had used traditional servers in those cases. Moreover, the use of AWS Reserved Instances has also been found to be about 250% costlier than if you were to get physical servers instead on contractual basis for the same period of time.

– Another key difference between the AWS cloud instances and physical servers are that the dedicated hosting providers of AWS services are far costlier than hosts offering dedicated hosting. Incidentally, costs for the cloud servers are as high as 450%.

– Besides the rates of cloud hosting services offered by cloud vendors, the costs of bandwidth or rate of data transfer on the cloud is much more expensive. This automatically implies that workloads which have higher bandwidth needs will turn out to be very costly. When you sign up for dedicated hosting plans from a host, you are likely to be allotted about 10TB along with a dedicated server. When you compare the costs of getting this with a cloud server, you will see that it runs into nearly 700 pounds a month in the AWS for the same amount of traffic. This is why when you need only a handful of servers for your business it is better to go for the cheaper providers in the market.

Aws_Migration
– When you invest in AWS spot instances or pre-built physical servers costs are somewhat at par. The outcomes depend on prices of resources and availability of resources. Usage costs of Amazon EFS for storage for a single month would be about 131.79 pounds for 1100GB while for a NAS server it would be about 120 pounds for 14TB. So, the latter can offer almost 13 times greater storage at far lower costs.

– When you compare the costs of running traditional dedicated servers which use MySQL with AWS-managed RDBS, you will see the costs are almost six times lesser when compared to running databases in AWS.

– These comparisons between physical servers and AWS servers help us understand that the AWS instances are best suited for cases which need multi-region redundancy and resiliency. These will have minimum resource needs because they will reduce management overheads. So, any small but complex hosting platform will become more affordable on AWS.

– The AWS comes up with proprietary solutions which can be of much use to application developers. They cut down the requirements for huge amounts of infrastructure. But when signing up for the trends in future for public cloud solutions, one must take into account factors like vendor lock-ins, disaster recovery plans, and data accessibility etc.

So, we can see comparable infrastructural cost differences between the AWS instances and the traditional servers. Most of the costs are seen to be higher on AWS cloud. This high cost can be justified by the fact that clients subscribing to AWS will not need support at all. However, this notion is not completely true. Support is definitely needed, even if it is acquired in a different way. For instance, you cannot completely cut down all your IT staff members when you move to the AWS. This is something which you cannot do simply because you will need the staff to manage your internal users. They will also work with app vendors to render app supports or fixes. This is carried out side by side with environment and infrastructure maintenance tasks. When all apps are shifted to the AWS, all the maintenance responsibility is not automatically shifted. The environment continues to be monitored as it must keep running smoothly. In fact, the internal staff will now need to know how the AWS works. When traditional servers are shifted to AWS instances, you will continue to need support and monitoring services as before.

In short, the staff continues to be important as always; they just work in a different way and they learn how to do things in the AWS fashion. This AWS approach is easy to learn when you enroll for certification programs. The bottom line is that adopting AWS is not a lightweight move as it is believed to be. At times, when support is needed, the AWS is found to be lacking and companies have to get third party advisors which in turn escalates the costs. This proves that the idea that AWS costs are always cheaper and they do not need support is not entirely true.

Cloud-Hosting-vs-Dedicated Hosting

Is Dedicated Server Better Than Cloud Hosting?

People are divided in their opinions about whether dedicated servers or cloud servers are more beneficial for a business. While cloud computing has become the new buzzword, the truth is that dedicated infrastructure still offers many key benefits over cloud infrastructure in many situations. What is important is to find a web hosting provider which can come up with the right blend of cloud and dedicated infrastructure for specific cases.

– It is seen that customers are usually not very clear about the infrastructure aspects. For instance, there are customers who are not sure whether to choose private cloud solutions only. But, what is needed is for you to build a set-up that will conform to your business interests. Once this can be determined, the web host will help its clients build the best security solutions centering on that infrastructure. It is usually seen that dedicated infrastructure is better equipped to offer more options for security and compliance needs to customers.

– Moreover, dedicated hosting solutions are known to provide greater flexibility and control which becomes necessary for satisfying specific application needs in security or compliance. In fact, dedicated hosting helps to reduce complexity because you are given the freedom to carry out changes in configurations and customize in a one-tenant environment. This is something that is never possible in a shared setting.

Cloud-Server-Hosting
– It has been argued by many people that dedicated set-ups are far costlier than the cloud. So, businesses can run their predictable workloads on dedicated servers. They can use cloud servers for handling sudden traffic spikes. This will help them to save costs. This freedom to customize the environment where your staff does not need to establish or manage the servers can be cost-savings for a business.

– It is often also stated that dedicated hosting will demand a lot of technical expertise. But this is not entirely true, especially when you have an experts’ team to back you up during implementation and planning stages and for maintenance. With a good web host to assist you it is possible to bridge all knowledge gaps. You can also learn how to get the most out of your infrastructure. Besides, you also learn ways to lower your monthly bills, even while using dedicated servers.

– Dedicated servers are being preferred to the cloud as these can guarantee superior performance. Even when you use reputed cloud solutions from AWS or Amazon Web Service you can never get the power you can get from a dedicated server which has been properly configured. In most cloud environments the underlying storage and networking are shared by many customers. This may result in the disk I/O becoming unpredictable. When some other client starts to transfer huge amounts of write requests you can experience slowdown. So, most problems arising in the cloud or VPS settings are because of the disk I/O issues and these are usually not easily resolvable inside a cloud framework. You can scale up the storage and processing power but scaling the disk I/O becomes a challenge.

– Transparency is also the key to resolving complex reliability issues and performance issues. It is important to be able to peer inside an application to find the possible bottlenecks. However, with cloud vendors, this is usually not possible. You cannot see exactly what has been powering the operations and cloud hardware tends to make networking and hardware problems incomprehensible. Since cloud is shared service the activities of others can directly impact workloads and underlying hardware errors may be responsible for outages. In a cloud, you will have to share computing resources like RAM or CPU with many others. So, cloud software will try to fence in the neighbors; however, this fencing is likely to have holes. Because of inherent designs, one user may overwhelm a local node and this may trigger temporary outages. Usually such problems stay undetected by providers and this is why you have to constantly track performance. Another problem with the cloud hosting servers is hardware errors. If such issues are detected or suspected the provider simply migrates the instance to other nodes in order to check if the problem is still there. While the cloud may make such migrations simple, with dedicated servers, these are not needed in the first place. This is because you can always check for hardware errors and nip these in the bud.

– People feel that cloud is inherently redundant. But a node is never more reliable than a dedicated server. When the node dies, the workload also crashes. This is almost the same as CPU or RAM crashes in a dedicated server. So, even with a cloud, you will need to build redundancy. For instance, The AWS set-up is not simple and it needs regular monitoring and maintenance. Cloud set-ups like the AWS usually have very complex layers which you do not need. Dedicated servers are safer in this manner as these issues are not there at all. So, there is no sense in choosing a complicated infrastructure when you cannot use it properly.

– Lastly, when you try to integrate complex services in a cloud, you will see that you are getting locked into their plans. This is a dangerous situation when the services or prices or support systems change for some reason. This is why development should evaluate all the smooth cloud migration options before choosing a cloud hosting service provider. Dedicated servers are more like commodities and migration to another provider is rather easy. This is why choosing dedicated hosting is a better option for meeting your technical and business needs instead of risking vendor lock-ins.

Services Which You Can Outsource to Cloud Storage

While online data storage can provide you with cost-efficiency, there are quite a few associated drawbacks with cloud storage solutions. So, it is important to know which services can change your businesses to cloud storage providers. For small and medium sized businesses, backups and storage is as important as it is for any large corporation. However, it is likely to consume a lot of time and you will also need a lot of manpower to perform these tasks. This explains why it makes sense to outsource these duties to a third party provider. With cloud hosting services coming in, such options are more readily available.

What kinds of cloud storage and backups solutions become necessary for SMBs?

For SMBs, cloud storage services are likely to come under these categories:

– Data archiving services offered by cloud vendors which helps in long-term storage for data that is rarely accessed.
-Data backup solutions for backing up the main data in the cloud.
– Primary storage which refers to the storage space for holding the main copy of data.
– Secondary storage solutions which refers to space for holding replica of the main data.

1.Cloud backup space refers to the storage space which is most extensively used by businesses for storing data. The clients will keep their primary data on-site and back this data up in the cloud through multiple methods. They are charged depending on the number of backups made. These backups will also expire after a certain time period or according to frequency. Making cloud backups is simple and you can use products like the Mozy which can identify data and then write the changed data into a cloud. Creating accounts is also easy and some providers even let you divide the accounts to be managed via a master account.

2.Cloud archiving solutions are very similar to cloud backup solutions, the only difference being that here the data remains permanently or as the client desires. In this environment, the client does not have a copy of data and the provider must provide additional data recovery services for protecting data archives. This data archiving service will depend on content and it will deal with emails or specific files.

cloud storage services3.Primary storage refers to a setting where clients have direct access to their files which would otherwise be housed in a local storage setting or a file server. These services may be deployed using multiple methods such as web protocols meant to work with this primary data inside the cloud. Companies like CTERA Networks or Twin Strata offer cloud storage services which seem to be local storage systems but actually cache reading-writing of files that are stored in clouds. The cloud storage solutions believe that only a few file are going to be accessed by businesses and once created, such files will be read or written only a few times. So, the gateway will archive such files inside the cloud and keep the files which are frequently needed in the local cache. But, for using such solutions you must predict the demands. When the cache is small, the users may experience greater response times for data retrieval from the cloud.

4.Secondary storage will offer replicas of primary data instead of a simple backup. For example, the Dropbox is the best known instance of secondary storage. It will replicate client data in a cloud and this can then be accessed through the Internet.  Secondary storage services are best suited for businesses keen to share data but not keen to buy dedicated file servers.

What are the pros and cons of cloud backup solutions?

– The main idea behind cloud computing is to offer resources to users so that they do not have to buy costly hardware. The clients are charged according to usage and typically on a monthly basis. The drawback is that it is hard to predict ongoing costs since cost vary depending on the traffic every month. Moreover, unless the services are rightly deployed, customers may get an astronomical bill after a month.

– Secondly, cloud hosting service providers was meant to offer scalability to customers. Clients would be free to scale up and down resources according to demands. They would not have to pay for additional software and hardware costs. When you must deploy storage in a traditional setting, you must plan so that you are prepared for the maximum demand. You cannot scale down resources when demands fall. This is why cloud storage is preferred by SMBs as they get resources in real time.

– While there are no universal standards, and reputed bodies have attempted to standardize protocols, providers have gone ahead with their own protocols and this is why customers face many issues. Switching providers becomes very hard for them because the proprietary structure puts constraints on data mobility. Management tools are also not standardized and each vendor has its own tools with unique settings.

– Cloud storage may also contribute to latency in performance; for primary storage, this is a big problem. Some vendors try to solve this by using caching devices and gateways. This may improve the situation but latency cannot be resolved completely. Caching devices instead bring forth many other problems around data consistency. To get backups you need to look at the time needed for data recovery. Data backups are usually on a short time scale and work for small scale restorations but not for large scale data restorations.

– You must also analyze security traits of cloud storage before you sign up. Data security breaches are usually subject to regulatory penalties and clients must know how the vendor plans to secure its data. The provider must use HTTPS and SSL for securing communications and encrypting data. There are many vendors which do not even offer compensations for data loss events. Even where they claim to have backups, there is usually no guarantee such backups will work eventually when needed. Finally, you must know how your services can be disrupted when a provider shuts down its operations and whether you can easily move to another provider in such a situation.

Journey to Cloud Hosting

Understanding the Basics before beginning the Journey to Cloud

Whatever may be you existing IT ecosystem or your organization’s future plans for cloud adoption, you can chose from a wide array of approaches to realize your cloud migration dream.

Needless to mention, you should tread with caution throughout the process of cloud migration by understanding that it is not mandatory to shift all IT infrastructure to cloud. In short, you must enjoy the journey to cloud by adopting a step by step approach.

It is also possible and advisable to follow a hybrid approach to cloud migration that allows you to retain control of the most sensitive infrastructure within the four walls of your organization. In this post, let us briefly review the most sought after cloud migration approaches.

Retiring the obsolete applications

The very first step towards cloud migration is to understand the extent of obsolete legacy applications that may never be used in future. In any organization there are at least two out of ten applications that are not going to be used anymore. Is In order to discover the usage patterns of different applications, one must revisit the entire gamut of IT portfolio as well as the statistics of metering. This can provide an in-depth understanding of applications that need to be retired in order to achieve a leaner and more cost effective IT environment. In fact, one can also distribute resources that can be freed up by retiring outdated applications including security arrangements.

Journey to Cloud Hosting
Lift and shift

If you are contemplating a large volume migration, then re-hosting or lift and shift approach can be a viable solution for you. It is backed by cost efficiency as well as ease of implementing cloud specific architectures in a highly optimized manner. According to some observers, a company can reduce migration expenditure at least by thirty percent.

This is considered as the quickest and also the easiest way to migrate data center to the cloud. The strategy of lifting and shifting is also known as re-hosting since it involves redeployment of applications to cloud native hardware ecosystem followed by implementation of relevant changes to the host configuration of the application.

In order to enhance appeal of the lift and shift strategy, Amazon Web Services have introduced tools that automate import and export of applications to obviate manual efforts. In spite of this, a manual process of re-hosting guarantees an enriched learning experience of re-deployment. Both approaches are designed to make your applications perform in the cloud environment.

Leveraging provider’s infrastructure

For optimization of applications in connection with cloud a re-platform solution can be an ideal alternative as it allows applications to run on the infrastructure offered by a cloud hosting service provider. It should be noted that there is neither any change in core architecture of application nor does it require spending developer cycle.

On the flip side, a re-platform strategy suffers from the considerable infancy of the market of Platform as a Service. The PaaS solutions fall short of delivering capabilities that many developers are familiar with in the environment of existing platforms.

In a re-platform option, one can use common resources over and over again. This can also include development framework, traditional programming languages and the current caches associated with the vital code of enterprise.

Re-imagine the architectural development

The strategy is also popularly known as refactoring since it is designed to accommodate higher scale or extra features that would support growing business requirements. Refactoring leads to greater performance of applications in a cloud environment since this would be next to impossible in a traditional setup of on-site infrastructure. Applications are re-architected to gain seamless compatibility with cloud ecosystem by making smart use of Platform as a Service.

Service providers are found to enable state of the art tools to developers through a user friendly platform. Whenever an application is refactored, it loses the legacy code apart from the known environment of development framework.

Repurchase as a strategy

Thanks to the extensive availability of commercially developed software applications that are designed to substitute traditional platforms as well as applications, one can implement repurchasing as a strategy of cloud adoption. When any organization is planning to procure SalesForce or any other software package, it is actually going to repurchase application because one or more business functions. The enterprise can easily migrate to any appropriate Software as a Service platform by following the repurchasing option. However there are few drawbacks of the strategy including vendor lock in. Some of the SaaS products can also result in interoperability problems.

Takeaway

Cloud migration strategy of any organization needs to be driven by individual requirements and business objectives instead of an urge to join the cloud bandwagon. It should also encompass the existing portfolio of IT applications because the migration process may also have a deep impact on your onsite IT infrastructure. Cloud adoption allows organizations to revisit and evaluate the existing IT portfolio to get rid of the inefficiencies.

Does Cloud Hosting Improve Security for Small Businesses?

Those in favor of cloud computing strongly argue that the cloud offers many benefits for businesses, large and small. However, skeptics argue that there are many data-security issues centering around cloud computing. They feel that such issues will be all the more critical for smaller companies which have to run on limited budgets and fewer resources. This belief however seems to have undergone changes as there are new reports which suggest that cloud computing is recommended for small businesses because it is boosting their security further.

How can small businesses benefit from security offered by cloud computing?

– Statistics reveal that small businesses which have adopted the cloud have witnessed a huge increase in their profits. They were able to get much higher returns on their investments. The truth is that smaller companies usually lack a very strong IT staff. This is why such security related duties typically fall on the owners. This makes it hard for the business owners to handle security concerns as they are already over burdened with regular administrative tasks. So, cloud computing offers businesses a great opportunity to outsource IT tasks to professionals in exchange for a nominal fee.

– Small business owners usually do not have access to high-end hardware; cloud vendors can offer them excellent maintenance for hardware and tech supports all the time through a scalable model. Nearly 78% of enterprises are expected to be turning to the cloud by the end of 2020. Data breaches are not likely to slow down because cyber criminals manage to find newer ways to access sensitive financial data all the time.

– Damages due to such unauthorized intrusions have huge impact on businesses and customers tend to lose their trust in businesses that have experienced data breaches in the past. The small business set-up is usually not built with security in mind, as compared to cloud technologies. A cloud hosting service provider’s entire infrastructure will be based upon securing customer trust and ensuring that sensitive data stays secure. This explains why the security is actually built into their system from scratch. Incidentally, there are even instances where the vendors will create environments to comply with regulations like HIPAA and PCI.

inside
– Since small businesses must work on limited IT budgets, they usually make use of their own hardware and networking equipments. The main cash flow is directed towards enhancing business growth and recruiting employees, thereby building a brand image. The cloud vendor will need high-end hardware for core competencies and the budgets are therefore spent on acquiring these. This means that small businesses which embrace the cloud will enjoy better access to high-end software and hardware, and also advanced security measures which are available in the cloud.

– When small businesses get caught up with too much work handling huge workloads, the maintenance of hardware and support services is relegated to the background. Employees responsible for updating security systems often get busy with other tasks. Moreover, a small business is likely to have outdated software which may create vulnerabilities within the infrastructure. If they choose to sign up for cloud computing, they would get technical assistance, software updates on time and hardware maintenance of the highest degree from the professionals. This directly improves their security arrangements. So, cloud hosting actually offers far advanced security measures for smaller businesses than they could have arranged on their own. As business owners do not have to worry about data security issues they can focus better on business development.

– Earlier, many cloud service providers had failed to deal with security concerns. But, things have changed today and most vendors have actually made their cloud security arrangements quite appealing for small enterprises. Small businesses have also realized the value of choosing cloud hosting for enjoying lower IT costs, less maintenance expenses and improved productivity. Cyber crimes have been growing by the day, but not simply because of an increased cloud adoption rate by enterprises. There have been instances of attacks for which the cloud cannot be blamed, like DDoS attacks, cross-site scripting attacks, SQL injection attacks etc.

– When you have shifted your data and operations to the cloud, your security concerns should ideally come down because of the access to latest cutting edge cloud technologies. It is therefore necessary for both customers and providers to understand that security must be flexible; it should be made more automatic than manual, eliminating chances of human errors.

When you move your data to the cloud, the primary risk is that you do not get to know who gets to access the cloud. This is why you need to have consistent control; the management of resources and identities within the public cloud has to be in sync with the resource and identity management within an enterprise. At the same time, if you can move identity management to a public cloud, you can also lower costs of these services. Your job is to assess the degree of confidentiality you need your data to have and then plan for securing that level of security.

Which Is Better For Your Business: Private Or Public Cloud?

Recent surveys suggest that nearly 93% of enterprises have already embraced cloud computing technologies is some way or the other. So, to stay ahead in this cutthroat competition, it is important to utilize the benefits which cloud hosting has to offer. So, embracing cloud technologies is not a choice anymore for businesses; rather, it has become a necessity. Modernizing the enterprise infrastructure is unarguably a key step in pushing digital transformations. Whether it is incorporating smart device or installing innovative applications, or capturing information for newer insights, the cloud is indispensable.

Why do you need to choose a cloud model for your business?

To ensure that your business does benefit from the cloud, it is also important to choose the right cloud computing model. It is the nature of your applications and data which will actually determine which cloud model is best suited for you. For mission-critical apps you need high-end availability, for web apps you need elasticity; for databases you will need data sovereignty and security. So, migration to the cloud is not as easy as it sounds. Like any other crucial business decision, this too demands extensive planning and research. This is when it becomes imperative to understand clearly the differences between the public and private clouds.

How will a public cloud benefit your enterprise?

In public cloud hosting, your data or apps are hosted on shared infrastructure which is provided by the cloud vendor. So, you will not need to provide for hardware purchase and maintenance and the host is completely responsible for managing the hardware. This explains why this type of cloud hosting can provide you with unparalleled scalability. Businesses are free to scale up or down their resources and pay only for the resources they use. So, businesses gain access to resources in real time and they can get the latest software innovations too.

So when you are an organization which needs fast deployment, a public cloud is the best solution. It is perfect for sites and productivity apps which have high bandwidth demands and need high availability and scalability. It will also need high end bandwidth connections which are backed by high-performance computing solutions. Businesses that need cloud bursting features, whereby there can be a temporary resource increase as and when needed, will benefit from a public cloud. Finally, public clouds will also offer disaster recovery services to guarantee business continuity when there are outages.

How can a private cloud benefit your enterprise?

The private cloud, on the other hand, is tailor-made infrastructure which is exclusively dedicated for your company needs. It may be either hosted on-site or in the data center facilities which are run by cloud providers. This implies that the biggest benefits you can get from this type of cloud hosting are control and high-end security. So, for businesses which must follow strict regulations and show compliance to accepted standards and government rules, this model is best suited. Private clouds will provide you with greater customizability for the hardware in order to cater to specific business needs. Most importantly, it will work only for your enterprise and you can therefore expect to get access to high-end enterprise-grade hardware, storage and networking.

So, the private cloud works best for businesses needing compliance and data security or those hosting very sensitive data. It is also useful for businesses which have applications needing high-performance accompanied by very low latency. Businesses which have limited IT departments or remote offices that are keen to install new on-site cloud models can benefit from this type of cloud computing.

Although, cloud platforms, public or private cloud, may offer businesses huge advantages as compared to traditional on-site ecosystems, enterprises will have to weigh the pros and cons of each hosting type before signing up. To conclude, the public cloud is your best possible solution when your business is highly dynamic and experiences seasonal bursts in activity. This is when it will also need a corresponding burst of bandwidth to accommodate the traffic spikes. Public cloud is also useful when you need the latest and recently-updated IT resources for expanding the enterprise but you do not have funds to buy these on your own. The private cloud is perfect for a business which has deeper pockets and is able to spend on investments. It is also recommended for enterprises with strict security and regulatory needs.

When you run a small enterprise which has limited budget, public clouds work best as you will only have to pay for what you will use. But, bigger companies with generous budgets can afford to sign up for private clouds. it also works to their advantage as signing up for private clouds is cheaper than renting huge volumes of public cloud services for running long-term projects. The private cloud will also give them complete control over the compliance, hardware, security, servers, SLAs and failover algorithms.

Why are Agile Development Practices Needed for Smooth Cloud Migrations?

When you are planning on moving to the cloud, you must take into consideration Agile development practices. Agile development basically refers to a sum total of many incremental software development methods. Each of these will be unique but they all share a common goal and core values. They involve continuous planning, testing, integration and evolution of both software and projects. These methods are all lightweight compared to traditional processes and inherently adaptable. The cloud essentially depends upon such methodologies. When you can adopt these Agile practices you are able to make cloud migration easier and hassle-free. Your organization can step into the cloud faster and innovate right away.

Usually most businesses will choose the conventional approaches where designing and planning for a product release is likely to take months. There will be a long period for developing the product followed by testing it and then releasing the software finally which may or may not live up to its expectations. In contrast, an organization which chooses the Agile development methods starts off with a MVP or Minimum Viable Product which is the least needed for creating any product that is “testable”. When the MVP is created, extensions and features will get added following short developmental spells, each continuing for about 2 weeks. So, Agile helps to guarantee faster speeds and speed is obviously the most important factor in a digital era.

How can you use Agile for cloud migration?

– You will first have to identify the cloud hosting services that need Agile. This is because applications including the important Software as a Service or SaaS apps such as Salesforce must be continuously updated. With the rapidly evolving cloud applications, the organization cannot possibly stick to the old waterfall development methods.

inside
– You can embrace Agile development methods as a company-wide effort. These technologies are typically first used by the engineering departments. This is why many businesses had been hesitant in using these practices because they felt this would only benefit the engineering teams. The truth is that without the operations personnel adopting such practices, the engineering teams will find it hard to function. Since the enhancements and features have to be approved by management team it is important to have these teams involved during the process too. So, with the engineering teams embracing the Agile methodologies the rest of the teams soon follow suit. Agile helps to make teamwork more effective and this is needed for managing and coordinating all the changes which are taking place at such a rapid pace. On the one hand the business becomes very responsive to buyers and on the other, it can respond faster to new market opportunities.

– When planning for a smooth cloud migration, you should also adopt the Agile development practices as part of the journey and not as a distinct exercise. Evolution to these practices is never going to happen overnight. It will end only when the organization enters a stage of continuous learning. So, you need a formal plan to adopt Agile and this plan must have routine training sessions and prefixed milestones.

– Even if you hire consultants for the migration, you must ensure these professionals make your internal teams a part of the journey. So, it is important that developers and operations staff work hand in hand with consultants and all the stakeholders must be part of the decision making exercises. Usually it is the business leaders who are unaware of this new style of development. They have to be helped so that they can successfully optimize Agile and exploit its advantages.

– Finally, the trick to making the Agile development practices work for you is to use the approach Lotito took to “eat his airplane”. You must break down the transition into small pieces and then handles these one instance at a time. So, what seems to be impossible at the beginning eventually becomes doable. You will need to have a lot of commitment and a solid plan for you to work incessantly to achieve your goals. If you can take baby steps, you are certain to reach the goal in no time. and it will only be a matter of time before you have a fully-functional Agile organization before you, one that is totally capable of handling all kinds of demands in today’s digital era.

Just like any new radically different method for conducting business, even the Agile methods have stirred quite a bit of controversy. The software community has been skeptical of its benefits although its usage in project after project has always yielded positive results. They have successfully delivered much better quality systems compared to traditional procedures in far less time. So, when you are working as a software professional, it makes sense to familiarize yourself with the Agile development practices.

Multi-faceted Advantages of Web Application Firewalls

There are millions of cyber attacks being inflicted on websites that may suffer heavily casualties in absence of rock solid defense measures. Hackers have gained advanced capabilities, thanks to easy availability of automated hacking tools. Wireless Application Firewall deserves a significant position among all technologies that are aimed at prevention of web based attacks that may originate from familiar or unidentified sources of application threats.

Emergence of WAF

Traditionally, firewalls have proved to offer effective defense against intruders with criminal intentions and it is but natural that these have undergone evolution to match growing threats that are being executed with advanced skills and amazing speeds.

The real risk presented by threats that could not be thwarted by legacy firewalls was their potential to impact the application itself as these threats executed attacks by using HTTP and other authorized protocols. These attackers could gain direct access to systems for hacking sensitive data.

Web Application Firewalls came into existence to effectively arrest modern cyber threats as the traditional firewalls could not offer reliable protection. There are several iterations of WAFs in relation with the extent of benefits that are offered for different costs.

inside
Different methods of implementation

The most basic implementation of a Web Application Firewall is known as network based WAF, which is essentially a hardware intensive firewall technology. Another feature of a network oriented WAF is its local implementation and the two features can be attributed to its advantages as well as disadvantages. Users can achieve remarkable latency mitigation due to its local characteristics in addition to reduction of impacts due to negative performance. Major drawback of network based WAF is the high upfront costs as well as expensive operation and maintenance.

Networking team is usually assigned with responsibility to look after management of network based Web Application Firewalls. Reputed vendors help users implement large scale configuration or deployment by replicating settings as well as rules. Centralized configurations and signatures further simplify process of securing multiple applications with considerably less efforts and expenditure.

Web Application Firewalls can be integrated fully within the application code or installed on the hosting platform to create an application based WAF for enhanced customizability as well as improved performance. This type of WAF is also much more economical due to lack of any hardware equipment. The most significant demerit of the application based WAF is its relative lack of scalability in large organizational setup.

Since application based WAFs reside locally, their management can be overwhelming as these WAFs are designed to integrate into applications. This implies necessity of local libraries apart from seamless access to multiple local resources such as compute power, RAM, and disk space within environment that is compatible. You should also note that these WAFs are built entirely as software programs, which requires active participation of security as well as server management teams throughout the process of installation and future management.

You will have to deploy cloud based Web Application Firewalls with hundred percent support of a cloud hosting service provider who will also look into the management aspects of these firewalls. Customers are required to involve their management and security team for its configuration by providing access to cloud based WAFs via web interface. These teams will be allowed to tweak the settings to define response of WAF in terms of different cyber threats. The threats may cover some of the most dangerous attacks including SQL injection and also the most dreaded DDoS attack. Needless to mention, your security and management team will also be empowered to switch off specific rule sets as per the need of the hour.

Amazing features of WAFs

Having understood various types of Web Application Firewalls we can now focus on some of the most interesting attributes of these modern security tools. If you are thinking that the advanced WAFs are only capable of blocking unwelcome or potentially dangerous traffic, then you are mistaken. The filter tool of some of the advanced WAFs is capable of not only preventing entry to the bad visitors but these firewalls can also attract good visitors to your site.

Firewall filters act as noise suppressors to improve site’s visibility for better ranking by websites. This is further backed by use of Content Delivery Network to facilitate potential as well as good visitors to find and visit your site without much difficulty. Combination of CDN and WAF is found to be a synergistic one and it enables qualified customers to drop in and browse your web presence for a greater monetization.

Web Application Firewalls are equally accountable for thwarting the bad guys from reaching your site so that your web presence grows without concerns of cyber threats. There are multiple service providers to choose from if you are interested in empowering your site with a hardened security profile that has ability to attract good traffic.

Key Cloud Growth Trends for 2018

Today, company executives do not look at the cloud simply as a tool for leveraging their infrastructures. Rather, they are more interested in finding out ways to use cloud computing technologies for strategizing business goals for the year 2018. The increased rate of cloud adoption is expected to drive unprecedented growth in public cloud hosting services where the market is expected to touch $184 billion. This is almost a 21.4% increase from last year when market had attained the $153 billion mark. Market is again expected to be twice the revenue by end of 2021.

The investments in cloud computing involve important decisions centering on security, innovations and ROI which are necessary to transform any business. While the public cloud can provide cost benefits as infrastructure is being shared, private clouds offer better security and data availability because of dedicated resources for individual organizations. Hybrid clouds provide a mix of both deployments and can be optimized for security, costs and performance according to an organization’s needs. So, the hybrid market is now expected to grow rapidly, with nearly 90% of companies investing in this model by the end of this decade. In contrast, the private cloud is expected to grow at a more relaxed pace but it will gain value in IT investment-related decisions since businesses want secure and dependable alternatives to on-premise data centers.

What are the trends in cloud growth predicted for 2018?

– According to reports by Gartner, there will be 4 types of cloud hosting services in the future, namely, IaaS, PaaS, SaaS and BPaaS or Business Process as a Service. According to studies, this BPaaS market is going to evolve at a slow rate compared to the other services as far as annual revenues are concerned. This is mainly because a large portion of the BPaaS clients are SMBs which have fewer needs for cloud business processes. The public cloud services on the other hand, will expand significantly and dominate the industry because of low-cost SaaS solutions.

inside
– As far as security goes, according to Gartner, there will be more focus on cloud security solutions for running critical applications or performance-driven workloads. Just because there is on-site datacenter deployment does not mean that there is robust security or that the cloud is a safer alternative. At the same time, if you forgo control to a third party cloud provider, it will not mean compromising your security capabilities. In PaaS and IaaS cases, where the organizations are finally responsible for securing workloads, growth of security service market reveals that this industry is coming out with effective ways to enable businesses to maximize the true potential of their public clouds.

– So, according to reports from Bain & Co, Statistica and KPMG, all these four types of cloud services, namely SaaS, IaaS, PaaS and BPaaS will expand aggressively. While SaaS is subscription based and mainly dominated by players like Salesforce or Google Apps, very soon new players will join the competition. Growth rates for PaaS are also impressive and it is expected to increase to almost 56% by 2020. The IaaS market which is currently dominated by Azure, AWS, GCE or Google Computer Engine is also expected to cross $17 billion by end of 2018.

– While a total of nearly 370 Exabyte data is currently stored in global data centers the capacity is expected to increase to about 1.1 ZB or Zettabytes by 2018 which is almost double the storage capacity of the previous year.

– Another important trend noticeable in 2018 will be server-less computing. So, developers can now create and operate applications without having to manage any infrastructure. This technology requires less time and less efforts and the release of updates is also less complex.

– Cloud-based containers are another trend to watch out for in 2018. These are alternatives to virtual machines and allow apps to get deployed in a rather quick and direct manner. This technology provides for faster release of software modules and guarantees better security.

– Artificial Intelligence of AI and Machine Learning or ML will also take center stage this year. Key players in this industry include IBM, Google and Microsoft which are making use of such technologies to offer cloud-based solutions for driving business growth.

– Finally, there is the growth of the fifth-generation or 5G network which is expected to dominate in 2018. Since volumes of data generated every day is constantly on the rise, it is important to accelerate Internet speeds. So, network providers are all working for a faster and improved connection for supporting cloud solutions.

So, from a business point of view, companies are mainly concentrating on automation and agility for facilitating quicker time to value. They are shifting all mission-critical apps to the cloud in order to address business needs for faster computing and scalability. With the public cloud hosting services, this is possible because it gives flexibility to scale up resources on demand. This is why public clouds are growing more and more in value for smaller businesses. These technologies are helping more and more SMBs and start-ups to compete against big businesses in terms of innovations. They can focus better on their key business offerings rather than having to spend resources and time on scaling up the infrastructure.

Does Location of Host Servers Affect Site Rankings?

Since cloud computing has made it possible for everyone to access data at anytime from anywhere on the globe, location of data centers does not seem to be as important as it used to be earlier as far as data availability goes. Cloud computing has unleashed a new trend of increased collaborations made possible because of cloud hosting technologies. At the same time, the importance of having hosting data centers close to businesses cannot be totally disregarded. Localized web hosting continues to be relevant to site SEO and extremely vital for user experience.

When you want to sign up with a web hosting company you are faced with innumerable choices. You will find that the same product is being offered by hundreds of vendors. So, you have to make the right decision at the first attempt.

Why is server location important for site rankings?

When choosing a web host, one of the factors that you should therefore consider is location of its servers and whether this is going to have any impact on your site’s rankings in search engines. The truth is that it may or may not affect the site’s SEO.

Since Google considers page loading speed as one of the key factors when ranking websites, it makes sense to choose hosting locations closer to your users to improve data speed. So, a good idea would be to host the site in a country which has most of your clients.

It is a well known fact that when page loading speed is slow, visitors abandon a site and move elsewhere. Nearly 53% of mobile users have been seen to abandon a website when it needs more than 3 seconds for loading. So, when you have servers at a distance from your user base, you will face slow loading speed.

Another reason to ensure that hosting servers are located closer to your users is when you are targeting the users in a specific country. It then makes perfect sense to place servers in that country. For other sites which target visitors from different locations all around the world, content delivery networks are needed.

As far as search engines are concerned, according to a former Google Search Quality Search expert, the company makes every effort to give the most relevant result for every user in every country. In this, the server locations in terms of IP addresses are obviously a deciding factor. When server locations cannot be near users, the company uses CDNs for faster content delivery to end-users. Alternately, they can also be hosted in countries which have superior infrastructure. So, locations of servers may not be the only determinant factor for site rankings.

In other word, while you should try to get a hosting server location preferably in a country where your target audience is, this is no longer an essentiality. This is because Google keeps making changes to accommodate a wider global audience. When your site gets hosted in UK for instance but its content targets users in Spain, you must set “Spain” in the webmaster tools. So, you do not have to set up your server in Spain but you can set international targets through webmaster tools. When your site targets a global audience with users from every part of the world, you can simply take the help of CDNs.

What is the effect of localized hosting on speed?

The location of servers will affect your site speed because the close your users are to the site’s data center, the faster is the content delivery. The time taken by servers to get and process any request is called latency. When the server location is in a different country than the user base, latency will be higher and this will impact page loading speed adversely. So, even a second of delay in page loading will cause 7% reduction in conversion rates. Almost 40% of viewers will leave a site if it fails to load within 3 seconds. According to Amazon, a slowing down of web page speed for just one second can translate into a loss of $1.6 billion every year.

For geo-targeting therefore, the server’s location has little role to play. If you use a gLTD or ccTLD along with webmaster tools, geo-targeting is possible regardless of server locations. So, to sum up, server locations will typically not affect the SEO rankings of sites directly. But, choosing a web host with servers near your users will obviously offer them a much faster access to the content. Since response time is one of the key factors for SEO, one can safely conclude that localized hosting will directly benefit SEO.

Physical locations of servers directly influence website speed. Loading speeds of any site will always affect search engine results. When you choose localized web hosting, you get to enjoy hassle-free payments that can be made in your own currency. So, each time an Indian user opens a website that has servers in India, he is going to experience much less lag or lower latency.

Vital Parameters to Look for While Selecting a Cloud Host

One of the most significant advantages of cloud hosting is secured and seamless performance of website with support of backup facilities for business continuity. Majority of organizations that decide to adopt cloud infrastructure are also amazed by remarkable cost efficiency of cloud services in comparison with running onsite IT resources.

Role of Cloud Services

Management and maintenance of on-premise IT can be a complex and demanding proposition with no guarantee of website security in the face of growing cyber crime related events. Onsite IT infrastructures need to be managed by expert professionals and monitored on round the clock basis. This can add significantly to the overall costs of manpower, electricity, bandwidth, security, and cooling.

In contrast, a standard cloud hosting service can effectively eliminate all hassles of maintain cost-intensive IT equipment so that your website can efficiently manage spikes in demands for uninterrupted visibility of the web applications in a feature-rich cloud environment. In this post, you can get accustomed with the most empowering benefits of cloud services.

Web hosting services have undergone several changes and cloud computing has truly revolutionized the way resource hungry websites are supported with scalable resources and redundant data storage facilities. Cloud hosting services also guarantee instant failover migration if your web presence is threatened with any unexpected outage.

inside
Secured Hosting

Security of website is a hotly debated topic these days on account of growing events of ransomware attacks and many more cyber crimes that involve data hacks resulting in irreparable damage to the reputation of business. It takes years to build a robust image of any business but a single malware or DDoS attack can destroy everything in a blink of time.

Highly reputable cloud service vendors are extremely serious about security of their clients’ web applications and sensitive data. They employ an impressive array of security measures including user authentication, data encryption, firewall protection, and other advanced measures of anti-virus protection.

In addition to these anti-hacking and antivirus measures, some of the most dependable cloud hosts implement routine security audits just to make sure that there is no breach of security at any level. Cloud Security must be the foremost consideration while choosing a service provider because after all you will be storing your business critical data in the cloud infrastructure. Make sure that there are multiple layers of security being offered by your prospective service provider as part of the hosting plan.

User-friendly and Reliable Hosting

Cloud hosting provides seamless access to the intuitive control panel among multiple iterations such as Plesk, cPanel or any other control panel that enhances controls without any complexities. Cloud hosting services boost your business focus by reducing need to spend hours in attending to technicalities of web hosting. Established cloud hosting providers are capable of empowering their clients with proven experience of managing a great number of user accounts with ease.

Supports growth

No business can hope to remain stagnant and any plan for business growth must be supported by assurance of instant provisioning of additional resources such as compute power, disk space, and RAM. Reputed cloud hosting service providers offer highly scalable plans as part of their cloud hosting offerings.

In order to access this features users need not be concerned about reboots or downtime that can cause serious interruptions as far as availability of web based applications is concerned. Additional resources can be provisioned without any hassles as it is only a single click operation.

Rapid Page Loading

Speed of page loading determines the overall site speed. It must be noted that latency can be detrimental to your business prospects since the page load speed has remarkable influence on the ranking of your website. If you wish to drive hordes of customers or potential visitors to your site, then a slow loading site can never be able to achieve this objective.

There are several reliable surveys that can be cited to establish the correlation between conversion rates and the speed of page loading. Your visitors will either abandon or will never return to your site even if there is mere 3 second delay in loading pages.

Website speed can be enhanced by placing servers in proximity of your visitors and cloud hosting services follow exactly the same method to boost page loading speeds. If a US based website has servers placed in various locations across Asia, then visitors from Asia will experience blazing fast page loads.

Uptime and other Hosting Features

Any cloud host that offers guaranteed uptime not less than 99.99 percent must back this claim by offering SLAs to that effect. Greater uptime is certainly a factor that will decide your web application’s performance when it is up and running. A service provider with top of the line low-density servers and branded world-class hardware is sure to support your website in the cloud environment with 99.99 percent uptime.

Cloud hosting features such as CMS, WP blogs, open scripts, and Wiki hosting are some of the vital parameters to look for while assessing a cloud service provider’s ability to enrich your hosting experience.

Key Avoidable Mistakes while Migrating to Cloud

Cloud adoption is gaining traction with more and more organizations moving their workloads to cloud environment for greater agility and scalability. However, the speed of cloud migration appears to have been impacted with only one in five global enterprises migrating to cloud.

This can be attributed to a number of factors but the most notable is the ignorance about some vital mistakes while executing cloud migration. Thankfully, these mistakes can be avoided by acquiring ability to watch for some significant signals.

Jumping on the Bandwagon

If you are considering cloud migration strategy in response to a competitor’s activity, then think twice. Your business is not like any other business because there are many aspects that may not necessitate a cloud environment. The cloud migration strategy must be strongly debated by all relevant team members before arriving at a common consensus.

Migrating Sans Modification

The commonest way adopted by many enterprises while performing a cloud migration is to simply lift and move data as well as code to a public cloud platform analog. This is due to the fact that such approach can save time as well as efforts. This method of cloud migration, without modification of the code, defeats the basic purpose of the entire exercise of cloud shift.

The long terms objective of enhancing performance with reduced cloud expenditure can only be achieved by implementation of cloud native localization. If this approach is not adopted, then a mere lifting and shifting of workloads will force the company to backtrack in order to re-factor applications. Applications that are not cloud–native can be very expensive on long terms basis in addition to being far less efficient. In order to empower applications with cloud native attributes, you will have to adopt a cloud native approach. Failure to do so will result in performance issues with applications that are not cloud native.

Lack of Focus on Database Issues

Post migration, one must deal with issues surrounding database while adopting a lifting and shifting approach. In fact there is a huge amount of cost involved in shifting of databases to cloud which are actually designed for on-premise environment.

Inefficient databases will destroy the very purpose of cloud migration. Databases that are purpose driven and cloud native, result in remarkably superior services as well as enhancement of performance with much better cost efficiency.

It is suggested that one must look at possibility of adopting databases with cloud native characteristics in order to eliminate huge costs on running databases in a cloud environment. Actually, your organization’s specific requirements ought to drive the decisions in terms of database section and adoption. This calls for considering cloud native choices.

Failure to involve DevOps

Lack of cloud team’s integration with DevOps team can prove to be a significantly costly mistake. Primarily, such communication gap will cause a severe hiatus in terms of DevOps’ involvement as its tools and processes will face disconnection from cloud. Secondly, the mistake will prove to be very costly due to downfall in productivity. This is absolutely avoidable if one executes development of applications within cloud by integrating with DevOps team while performing testing and application deployment.

If there is a failure to integrate DevOps with cloud teams right from the word go, then you are only putting off an important step while migrating to cloud. Cloud is no place for anything that is suitable for on-premise platforms and therefore your lack of coupling DevOps and cloud teams together is totally unjustified.

Not Choosing the Right Partner

If your prospective cloud service provider is not offering written commitments in form of Service Level Agreement, then it is better to move away. An ideal cloud service provider is capable of providing service guarantees in black and white. Many CIOs make a common mistake of comparing cloud providers on the basis of costs.

If you have chosen the cheapest cloud service provider, then there is every possibility that the plans will be loaded with hidden charges which will play havoc with your IT budget.

Your cloud service provider must be capable of enabling remote management and control of your cloud resources. In doing so, the cloud provider should address all concerns about security of your digital assets. Reputed cloud service providers maintain a layer of isolation to safeguard security interests of every client.

Stringent security norms including two factor authentication, user specific credentials, and uncompromised attitude towards compliance must be the major highlights of your cloud service provider. All end users of cloud services in your company should receive in-depth training so that majority of technical issues can be resolved without making a frantic call to service provider at odd hours.

In conclusion

Cost saving, enhanced performance, and other compelling advantages of cloud migrations can be appreciated if these mistakes are avoided in the first place. It would be better to align your business needs with cloud benefits instead of joining the crowd in a race to cloud adoption.

Serverless Cloud Computing – A Real Game Changer

Although the term ‘serverless computing’ is a contradiction by itself, it aptly explains the purpose and benefits of such functionality. Automatic provisioning and de-provisioning of resources without leveraging actual servers, has always been a long cherished desire of developers as well as CIOs.

Brief Insight about Serverless Computing

Thanks to cloud computing, it is now possible to easily procure a wide spectrum of tools, processing power, and storage to address fast paced market scenario. However, a select few IT experts are contemplating a far more efficient method of renting huge power of cloud computing to obviate complex management of cloud infrastructure. The idea is to adopt serverless computing.

By going serverless, one does not need to allocate cloud instances that are dormant for a long time before being accessed for driving specific functions or applications. This can be understood by considering devices that are designed to support operations of IoT. These sensor driven tools are only activated whenever a user clicks on the app from his or her internet enabled device such as a smart phone. This is a classic case of event oriented computing.

By adopting serverless cloud computing, one does not need to waste developers’ energy in managing server resources and focus the same on the most important task of writing codes for individual functions. This also explains the use of term Functions as a Service. In order to understand serverless computing, it would be easy to consider the example of renting a house. You are neither supposed to worry about maintenance of the house nor are you required to pay the cost of construction.

Emergence of Serverless

Serverless made its debut in 2014 when AWS Lambda was presented by Amazon and it has been a seamless source of amazing innovations and solutions since then. Serverless is also improved the way codes are written and applications are deployed.

In a serverless environment application logic is executed in such a way that all physical systems including operating systems, virtual machines, and servers are obviated by means of software architecture. The serverless ecosystem leverages physical servers and VMs while running on top of an Operating System.

Unlike other conventional cloud computing environments, a software developer can enjoy freedom from the time consuming tasks of infrastructure management to concentrate on his or her core competency. In a serverless approach, developers are only concerned with use of the infrastructure and not the nitty-gritty of infrastructure management. Needless to mention, users of serverless computing services are not required to pay for Virtual Machines or server equipment.

The entire onus of smoothly running IT infrastructure is on the third party provider of cloud computing services. Service provider also has liberty to dynamically shift resources of the cloud infrastructure and allocate to different users by following a need based approach.

Usually, there is no need to implement a workload permanently for a specific customer since specially developed software can manage the process of managing requests from all customers. Service providers use the amount of time required to process requests from a customer as the basis for billing.

In comparison with operating a dedicated IT infrastructure, a serverless approach offers amazing benefits to users that need to address frequent demand fluctuations. In addition to freedom from management and maintenance of on-premise server equipment, you can effectively handle unexpected rise and fall of resource requirement while operating in a serverless environment.

Serverless Computing- Merits and Demerits

Users are able to eliminate need to employ system administrators because serverless computing solutions help simplify packaging and look after deployment. There is a considerable mitigation of software complexity as serverless computing is capable of being implemented as functions. It is therefore ideal for addressing needs of micro-services.

You can significantly reduce operating costs as well as efforts that are required for scaling to help developers focus on their primary job of effective coding and faster delivery. Moreover, there is no need to worry about upgrading the existing servers or adding new ones from now and then.

On the flip side, a variety of performance associated concerns prevent serverless computing from being considered as the perfect approach. The entire infrastructure suffers inherently from possibility of greater latency. It needs to be understood how the model can reciprocate requirement of applications without latency. Individual allocation of virtual servers can alternatively be used for running applications that are performance-intensive.

Till the time specific tools for debugging as well as monitoring have not been developed, these activities will continue to be a major constraint of any serverless environment.

In Conclusion

Developers can pay their seamless attention to coding in order to achieve faster deliveries with help of a serverless computing solution. The serverless approach is an ideal way to reduce complexity of system administration by eliminating complex tasks of configuring VMs or dedicated servers.
