The cloud market continues to grow in 2016. Companies are now more willing to adopt the cloud technology. But security being one of the biggest concern, it is often difficult to choose which cloud style to choose- Public cloud or on premise cloud. Public clouds have a very nice structure and security mechanism which helps the user use the platform economically and securely. On premise setup will require a large investment. But then there are some data which can't be moved to the public cloud. For regulatory, compliance or customer demand reasons, a company can't expose data to public clouds. So the company must invest in the security of their applications and let the public cloud giants secure the infrastructure.

Public cloud has many advantages. They provide flexible and affordable virtual machine deployments and can boost an organization's data backup and workload-scaling capabilities. But, there are some drawbacks of public cloud. One of the biggest disadvantages is its multi-tenant environment. Another disadvantage is that public cloud providers own the hardware and control the software associated with it, so that they can make some changes at will. Running virtuak machines in the cloud make them costlier is another disadvantage and last but not the least disadvantage is how public clouds can complicate backup processes.

According to a recent finding by Technology Business Research (TBR) it was found that business decision makers are seeking cloud professional service guidance at twice the rate of private and public cloud vendors. It was also found that public, private and hybrid cloud integration guidance demand will follow basic cloud professional services growth in coming years and private cloud adoption rate are expected to reach 85 percent by 2018. TBR also believes that there has been an evolution in the type of private clouds adopted -- with 65 percent of third-party-delivered private clouds, compared to 35 percent of self-built private clouds and they also forecasted the growth of the private cloud market to grow at a 15 percent CAGR to $72 billion in 2018.

Organizations who have sensitive data and are required to put their sensitive data in the cloud opt for hybrid cloud. Companies looking to expand their presence into the cloud also opt for hybrid cloud. According to a report, the growth rates of both hybrid and private clouds come in the range of 40% to 45%. This article by Sharon Gaudin (Computerworld UK) describes some basics that every IT manager should consider if enterprises are looking to use a hybrid of public and private cloud set-ups.

Cloud Computing connects large pool of resources through private or public network and this technology makes infrastructure planning easier. Cloud Computing provides dynamically scalable infrastructure for cloud based applications, data, and file storage. Businesses can choose to deploy applications on Public, Private, Hybrid clouds or the newer Community Cloud. Public clouds are provided to the public by a service provider who hosts the cloud infrastructure. Public cloud providers like Amazon AWS, Microsoft and Google own and operate the infrastructure and offer access over the Internet. With this model, customers have no visibility or control over where the infrastructure is located.All customers on public clouds share the same infrastructure pool with limited configuration, security protections and availability variances. Private cloud is cloud infrastructure dedicated to a particular organization. Private clouds allow businesses to host applications in the cloud, ensuring data security and control, which is not ensured inn a public cloud environment. Hybrid Clouds are a composition of two or more clouds (private, community or public) that remain unique entities but are bound together offering the advantages of multiple deployment models. A community cloud is a multi-tenant cloud service model that is shared among several organizations and governed, managed and secured commonly by all the participating organizations or a third party managed service provider.

Cloud computing enables companies to get agile, leverage infrastructure on demand, and run it like a utility. The cloud environment provides flexibility, scalability and continuous availability with expert services. Rapid prototyping and to solve business process through analysis can be easily done by having access to a cloud environment. While the benefits are many but, the public cloud does not fulfill the needs of individual organizations which need better privacy and data security. In public cloud, many clients can access virtualized services from the same pool of servers and resources, but in private cloud clients mainly access services from a distinct pool of physical computers. Nowadays many organizations opt for a middle way i.e. hybrid cloud solution to avoid disadvantages of private cloud.

AWS has been authorized to operate under FedRAMP(U.S. government-wide general security standard) since May of 2013. Under FedRAMP, AWS has already made contracts with U.S. Military, Air-force & Navy. With the recent authorization from United States Defence Department’s cloud security standards, AWS can work with all agencies within the U.S Defence Department from now on. It’s like a new feather added to the AWS hat! Teresa Carlson, AWS’s vice president for the public sector, said the new certification could mean more than just new Defence Department business. This would let AWS work with more defence agencies to host several sensitive projects.

For many enterprises, the most recognizable model of cloud computing is the public cloud model, which provides ultimate scalability, flexibility, location independent access and is of course cost effective. But workload evaluation is important before an organization moves to the public cloud. There can be situations wherepublic cloud such as AWS costs may far exceed on-premise infrastructure costs. According to research firm Gartner, the evaluation every organization must undergo before moving into a public cloud consists of taking into account few major things. These are: number of machines an organization will run, number of hours per day or per week they'll run and the amount of storage these machines will generate. The evaluation should also include the licenses that need to be paid for on a recurring basis; how many times and how often snapshots occur; the rate of change in the data; and how much new data they are going to generate. Mike Ryan, consultant, Epitech, said that “You're paying for the elasticity of Amazon, and if you're not using that, it makes sense to bring things into your own data centre”. The scaling flexibility of public cloud is great during the growth phase, but which solution is the best from an enterprise long term perspective?
