Why is Cloud Security Vital for the Healthcare Industry?

It is a known fact that the healthcare industry is perhaps the most vulnerable to cyber threats these days. This does not come as a surprise since the presence of personal and financial details about millions of patients is bound to attract cybercriminals. Only a year back, the WannaCry ransomware strike had put the UK NHS in great jeopardy, leading to collapse on many of its facilities and appointments and operations getting cancelled. This is why when healthcare organizations decide to move to the cloud, there are still some grounds for suspicion.

Studies show that almost 61% of healthcare enterprises are worried about malware attacks. Incidentally, healthcare is also the only industry in which data encryption is seen as a top security concern. Healthcare compliance rules usually mandate data encryption but the downside of this is that this may multiply a provider’s cloud charges. So, the smaller organizations naturally stay away from cloud migrations or consciously refrain from storing healthcare data in the cloud. Again the healthcare organizations have stated that employees are the biggest threat to cloud security and nearly half of the survey respondents feel that human factor is most responsible. But this has not improved visibility into user activities and very few organizations actually know what the IT staff does. While the IT staff may understand this mismatch they do not get the management supports for addressing this issue. In fact, there is very limited management support for deploying cloud security initiatives.

A few years back HIPAA compliance used to be a challenge. But the recent HIPAA Omnibus Rule that came into effect since March 2013 changed all of that and improved privacy for patient data. This is the time when cloud providers have faced challenges from healthcare organizations. They have continued to work to make sure that this migration to the cloud is secure and hassle-free.

How to overcome challenges to cloud security in healthcare

– While there may be many concerns when you are deploying cloud security solutions in the healthcare industry, there are also ways to resolve them to obtain a robust cloud strategy. Healthcare data is vulnerable because it is increasing in value all the time. According to Ponemon Institute studies, average healthcare information breaches can cost nearly $380 for every record. Where the average worldwide cost records for all the industries is around $141, for healthcare breaches the cost is more than twice the worldwide average. When you try to put healthcare data in a cloud, you, therefore, have to design the infrastructure and connections in ways so that the data is totally safe. This is why now data centers and cloud providers are working in sync to safeguard healthcare data. When you are still not convinced about the security measures, you can always talk to the data center or cloud services provider which specializes in migrating workloads and apps into the cloud. For instance, there are many instances of using hybrid cloud architectures for meeting HIPAA standards.

– When you are not able to design the architecture properly the cloud costs may be too steep. This is something which many businesses have faced during the earlier days of cloud computing. But cloud design has indeed changed today and it is possible to granularly identify the workloads, data points and users in a cloud system. So, businesses can predict data requirements, usage and data locality depending on your needs to give you the best prices.

– Network reliability used to be a huge point of concern for the healthcare industry. When the network is not reliable or stable the data sets and apps which are meant to save patient lives cannot work optimally. There are bound to be limitations on services you are capable of delivering. Today, in an age of telemedicine, there is absolutely no scope for unreliability or latency. This problem was mainly due to design. You must consider the importance of an app or data set, where the access happens from and data proximity before creating a design. The need of the hour is a fast-paced network connection. This will ensure that all your workloads and key apps are always available.

– You can use many kinds of data storage options like cold storage, primary storage and archival storage. It is your choice when it comes to the type of storage you will use and where the data will be housed. Since data is critical you must understand data sovereignty and data locality requirements. Cloud hosting service providers who are working with healthcare organizations are going to assist you to keep the data where you need to and then help you access this easily.

– When you have decided to move to the cloud, you must have a good understanding of the service level structure even if you already have healthcare instance. So, you need to know whether you can survive without a certain app or how long you can go on without a particular data service etc. This means you should review your SLAs from time to time. Since apps and data are continuously changing, the SLA must change with it too.

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.

Understanding Multiple Aspects of Data Centers In View of Big Data

The impact of big data can be understood from the fact that ninety percent of all data is produced in the span of last two years. It is predicted that velocity of data generation will continue to accelerate further in near future. In view of this data centers need to gear up to handle the massive data explosion.

Data centers play vital role in handling all types of data storage and data handling workloads. The looming challenge of big data must be effectively handled by data centers that need to improve data center management tactics. We need to appreciate and analyze impact of big data on various aspects of data center capabilities.

Capability of data center’s electrical infrastructure

Every data center heavily relies on the capability of its electrical infrastructure for managing incremental volumes of data. It is vital to understand potential of the existing electrical infrastructure in order to assess the capacity of data center to face future challenges of big data.

In almost all cases, electrical infrastructures of data centers are not geared up to deal with challenges of big data. This underlines an urgent need to upgrade existing infrastructure or to deploy new and high performance electrical infrastructure facilities.

In view of this several organizations have initiated procedures for estimating sustainability of their current capacities and preparing expansion plans for accommodating future needs of electrical infrastructures. Future data center facilities need to have enhanced data management capacities as well as reliability while handling such excessive workloads.

Although, big data may not have a direct impact on the power consumption aspect of data center, the amount of power consumed by data centers that are involved in handling big volumes of data is significantly more in comparison with ordinary data centers. Expansion of electrical infrastructure results in multifold increase in power demand. Naturally, the costs of data center operations also multiply due to greater power consumption. This explains importance of cost planning while preparing to handle larger data workloads due to emergence of big data.

Data center managers are also required to consider data center location while estimating costs. As per the existing trends, data centers are either built or shifted to locations that are away from major cities. Amount of power consumed for data center cooling contributes to almost 40 percent of the total power required to run data center. This also explains why majority of data centers are coming up in the northern hemisphere which is relatively cooler.

Impact on storage infrastructure

Storage infrastructure is another component of data center that is expected to be influenced by big data. The existing data centers are designed to handle relational data and the challenges of big data are going to add structured data, unstructured data, and semi-structured data to underline need for enhancement of storage infrastructure of data centers.

These new data center infrastructures will need to accommodate new features of big data including variety, veracity, velocity, and volumes. This is certainly involver more complex storage needs and the existing data center must pay attention to these features while developing new storage infrastructure.

New traffic patterns

In addition to the huge data volumes and variety of other features of big data, data centers should also be able to handle multiple sources of data. There are also different formats, and volumes of data are to be considered. In order to address demands of traffic patterns of big data center engineers are contemplating about revolutionary designs and their deployment methods. In order to acquire compatibility with new traffic patterns and types of data one must pay attention to the storage architecture of data centers.

Data center security

Big data explosion is driving a big change in multiple aspects of data centers including data center security. Since big data refers to huge volumes of data from variety of sources, security of data storage gains prominence. Obviously, security of big data is another overwhelming aspect of its impact on the operations of data centers.

Most of the data has extreme importance in terms of analytics and organizational information. Data centers are supposed to implement high end security measures to protect data at various levels including network level, application levels, and storage level. Appropriate and comprehensive security planning is essential for mitigation of threats from all quarters.

Impact on data center network infrastructure

We need to accept that the existing data center inks are based on Wide Area Network with moderate requirements of bandwidth. This arrangement of network suffices the purpose of applications that were originally designed to interact with data centers only with help of requests generated by humans.

The inbound bandwidth requirements will exponentially multiply with the huge data volumes coming in from big data sources. Obviously, bandwidth requirements of network will significantly increase and data center infrastructures will have to be upgraded or modified for supporting greater volumes and velocities of big data.

Big data is going to influence almost all aspects of data center infrastructure across the globe. The most significant challenges will be to accommodate rise in power and cooling requirements. This explains the need to design future data centers by considering challenges of big data.

Building a Backup Strategy: Using Cloud And On-Premises For Best Data Backup Strategies

Technical issues can cause major setbacks even to companies that are using state-of-the-art cloud hosting technologies and advanced processes. Recent incidents involving two international majors show how ill-prepared companies are when it comes to adapting backup systems. Experts state that companies can save themselves tons of trouble if they have an efficient backup system in place on premises or a cloud-based one.

Are You Looking For Data Backup Systems?

Businesses are not serious about using the best backup systems and strategies as they are quite convinced that the next victim of technology disaster will be anyone but them. A solid backup plan is all it takes to prevent a major disaster from hitting your business. Companies with a foolproof backup strategy that’s regularly updated can focus on their goals more intensely as they won’t have to fear a situation where they have no access to data which can affect their functioning adversely, especially in the critical customer service section.

One key reason why companies do not put a good backup strategy in place is because to have an efficient backup plan they must invest significant amount of time and money. While established businesses generally have no problem with resources investment, for startups and new companies, this could pose a problem owing to limited budget and a skeletal staff that they would rather use for crucial business development tasks.

Avoid Shortcuts

Some companies opt for shortcut solutions that come cheap and promise high performance. Such solutions are highly suspect because they are not properly tested or optimized. When the data system is stretched, the backup process can fail leading to major availability and performance issues that can deliver a telling blow to your reputation.

Backup Strategy Options

Choosing the right backup strategy for your business is not easy unless you plan it properly in consultation with an expert. You will have to first decide which information needs to be backed up on top priority and which need not be secured. No organization will need all their information on demand in the backup system. It is important to note that data storage is an expensive process. Prioritization is necessary to make sure that you don’t spend your limited financial resources on storing data that is not of critical importance. Only mission-critical files and applications that your organization needs regularly must be included in the backup system and considered for regular update.

You will also have to choose the right storage method. In fact, you will have to assign the backup process to a qualified IT professional who can be in charge of monitoring and testing the system on a regular basis. If the data you are handling is of a sensitive nature, you must ensure that the best backup and storage technology is used to ensure its safety.

Why Location Is Important

While choosing a cloud backup system, you must pay close attention to the location as this could prove to be an important factor. On-premises deployment is recommended if you want your critical information to remain closer to your organization. You can choose from DAS and NAS storage solutions. DAS stands for direct attached storage while NAS expands to network attached storage. They are advanced form of storage systems that are designed to withstand power outages, and disasters such as flood and fire.

Other Options

You can also consider building a fully-equipped cloud from the ground up by buying the necessary hardware and components or choose the service of a private cloud hosting provider to provide high-quality storage solutions that can keep data protected from disasters. You can also store your data offline by using magnetic tape, DVDs or discs. Physical media is safe and remains unaffected by outages or system failures but there is a major drawback. If there is a failure, getting the system back on feet can be a long-drawn process.

Cloud computing is gaining in popularity with many companies are choosing this reliable route to secure their data backup process. If you too are considering backup solutions, make sure you consult an IT expert to know which option best suits your business data protection needs.

Some providers incorporate their own software on top-ranked generic cloud services such as Google and Amazon. This leads to a situation in which they can enjoy redundancy-related benefits of redundancy but do not have the ability to control the situation or shoot down troublesome issues.

Another option is to use the services of providers that leverage their own purpose-built cloud data centers and allow companies to make their choice of backup hardware. In such an arrangement, the provider is responsible for maintenance, uptime and backup tasks.

You can also consider using the services of providers with their own their hardware powered by third-party software for data management during backups. This is a popular arrangement that’s extremely reliable and used by many companies. Lack of customization options is a downside.

Review of Hadoop as a Service Based in Terms of Security and Cost Factors

The Java based and open source programming framework, Hadoop is extensively used in a distributed computing environment for supporting storage as well as processing of huge data sets. It is one of the highly respected tools for utilization, management, and analysis of Big Data. Hadoop empowers organizations to make the most of even extremely complex data sets and initiatives.

Many organizations are able to exploit Hadoop’s amazing attributes including scalability and flexibility for building high value products by accessing only the basic package without incurring huge expenses.

Large scale versatility and fascinating array of applications have lead to perplexity as to the use of Hadoop in cloud or in an onsite environment. There are four basic considerations that need to be taken into account before deciding whether to use Hadoop in cloud or otherwise.

Hadoop-in-Cloud

Security concerns

Vulnerability of cloud to hacks and security breaches has come to light especially because of breach of iCloud from apple. It is now a well established fact that no organization, irrespective of its status, is completely immune to hacking attempts. The same argument can be extrapolated to state that the Hadoop employed data is also prone to cyber attacks if the same is stored in cloud.

This does not imply that the data in cloud is far from being safe and secure. Thanks to the amazing advancements in cyber security related technologies, there is a consistent development of security systems to stay one step ahead of these hackers.

In terms of numbers, there has been more number of thwarted attacks than number of successful hacks. Security breach of iCloud is attributed to a weak password and not to susceptibility of security systems against hackers.

Cloud as an environment for data storage is not to be blamed for lack of data security. Rather the issue of security is related more to the point of connectivity during data download and upload. The transit period between the cloud source and the destination is vulnerable to attacks.

Hence we can safely confirm that the implementation of data on-site is far more secure while the data is being used within the seamless boundaries of the system itself. In essence, you can completely prevent chances of a hacking attempt by defining and controlling access to the internal database.

This means that the accountability of security of the data remains entirely with the internal IT teams leading to more complex and cost intensive security system upgrades.

Judgment- On-site solution are far more secure than cloud, provided the implementation of Hadoop is executed within a closed network rather than harnessing in-cloud environment for the implementation. Security cannot be assured if an open system is being leveraged for Hadoop implementation.

Cost factor

In-premise- Onsite implementation of Hadoop is clearly more cost intensive than in-cloud option. This is because of excessive allocation of resources for acquiring an array of servers for data storage. These servers need to have compatibility of processing power with prerequisites for effective handling of queries. Additional IT manpower may be needed for efficient management of complex servers.

Add to this the huge costs needed for purchasing high end equipment for system upgrades and cost for acquiring additional space for positioning that additional equipment and associated cost for implementation of security measures.

In-cloud- There are no additional costs for in-cloud implementation of Hadoop apart from the monthly subscription fees that depend upon usage needs. These are directly proportional to consumption of system resources.

The payment approach also facilitates ease of scalability since user needs to go on purchasing higher packages to add to the existing resources without need to make huge investments to accommodate growing needs. It is also possible to down scale by opting out of the higher plans.

Judgment- Cloud based Hadoop implementation is not only cheaper but also more scalable than on-site approach.

Practicality of implantation

Ease of access from any location is one of the most important features of in-cloud Hadoop implementation. Companies can operate data from any location via Internet connectivity for accessing progress, checking reports, or assessing work. This option also supersedes on-site implementation of Hadoop in terms of flexibility of operations.

If you are looking forward to remotely administer databases, then there is no option to cloud based implementation of Hadoop. On-site use of Hadoop does not permit remote access due to rigid measures of security and an attempt to achieve capability of remote access in on-site environment would not only be irrational but would also compromise security to significant extent.

Judgment- Cloud based systems offer freedom to work from any location

In conclude

Cloud has an edge over on-site Hadoop implementation. Use of Hadoop is clearly a better choice, although the other option has its own place in terms of implementation of robust security measures. It should be noted that on-premise Hadoop is an expensive proposition due to high costs of system upgrades and maintenance.

On-premise implementation continues to emerge as an ideal choice for organizations that need to implement serious security measures due to presence of classified data that is highly prone to cyber attacks.

Benefits of Colocation Server

Set up & maintenance cost for building an in-house space to keep your company server may not be affordable by every company. It requires a separate section in your company premises equipped with the necessary facilities. You need to hire skilled IT personnel, buy hardware and bandwidth to keep the computer system up & running. You could avail the same amount of bandwidth through colocation at a lesser price. You get the provision to keep your server at someone else's rack.

Your server would reside in a secured data center saving your capital expenditure. The power is supplied by the service provider and requirements could be scaled-up on demand basis. You could meet your fluctuating and seasonal demands with the colocation service provider beside you.

Let's discuss what a colocation service offers to you:
Improved Connectivity : Fully redundant network connections making sure customers business critical applications run smooth without any hiccups.
Enhanced Network Security :Latest firewalls and IDS systems for detection & prevention of unauthorized access.
Redundant Power Supply : This is done through a combination of multiple power grids.
Bursting Capacity :Option of bursting to higher bandwidth levels as per website traffic. Capital investment is avoided. You get bandwidth at a lesser price because of Economies of Scale advantage for the service provider.
Room for growth : The infrastructure in terms of space, CPU utilization, RAM, bandwidth, processor power could be expanded to fit the requirement of your company's growth.

Colocation server could be your first big step towards cloud hosting, and small firms seeking to avail cloud computing services in future could begin their journey with colocation service.

Dedicated Server – Easing Out Your Traffic

If you are a small firm, or a start-up company aiming to establish your name as a brand in the market, shared server will work just fine for you. Shared server hosting offers a low-cost solution to organizations, as the server is shared by a number of websites. But as you start receiving high traffic on your site, switching to a dedicated server is a sensible idea. Despite its high-cost, it's profitable to the companies as it offers a wide range of benefits

Reliability It's reliable as your server isn't shared by any other site. There is no service degradation reported and downtime is zero to minimal

Administrative Access You get the root access to install applications or software. You can perform all sorts of modifications or customizations as per the requirement

Safe Storage It is challenging to maintain a server in your company premises. Server has to be kept in a temperature controlled environment and away from moisture. It also takes up a lot of space, hence demanding a separate room. This might not be affordable to small organizations. Going for dedicated server hosting, solves this issue

In a nutshell, dedicated servers are suitable for high-end users getting high-traffic on their sites

Cloud Hosting – A Silver Bullet Solution

"Have your cake, and eat it too".

This is the provision that cloud hosting offers -control of a dedicated server at the affordable price of a shared server. Cloud computing depicts a cluster of servers that do load balancing for websites. It offers various facilities like scalability, isolation, better control at a lesser cost than a dedicated server.

Isolation  Sometimes the neighboring site that shares a common server with your website eats up all the resources leaving your website in a resource crunch situation. There isn’t enough RAM, Processing power, CPU utilization left to serve your site. This risk is mitigated in cloud hosting.

Scalability Pay for what you use. If you need more resources at the time of high traffic, cloud will provide it.
