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.

– 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.
