Many companies have looked at their choice in cloud computing as a decision between a public and private cloud. This is no longer the case. The decision does not need to be either one or the other; it can also include both types of cloud as a valid option.
The hybrid cloud, as defined by the National Institute of Standards and Technology (NIST) is, “a combination of public and private clouds bound together by either standardization or proprietary technology that enables data and application portability,” and a hybrid cloud can provide the best of both private and public clouds for many users.
Although it is by no means an exhaustive list, below are five benefits of the hybrid cloud model that may not have been recognised by companies exploring cloud computing for their business.
1. Hybrid clouds do not require complete replacement of existing IT infrastructure. The building of a private cloud can require months of effort from a company’s IT department with a significant investment of both time and money. In contrast, the hybrid option allows the use of public clouds immediately for any increases in capacity and scalability that are required while you accomplish any needed changes to your infrastructure.
2. Hybrid clouds offer the advantage of added security over a public cloud, by allowing sensitive IT resources to remain outside of the public cloud, safe and sound behind your own firewall and on-premises gateway. Plus, should you eventually decide to migrate your data from your private cloud to the public cloud, that data movement is much easier than it is from a traditional server based environment.
3. Improved scalability and provisioning at decreased cost are another benefit of the hybrid cloud. Resources can be allocated to the cloud for short term projects at much lower cost when compared to the need for additional resources that would otherwise require immediate capital expenditure on local IT infrastructure in order to complete a resource intensive project.
4. The hybrid cloud can be used to buttress an argument for cloud computing when faced with reluctance from management. It can help raise the comfort level of those individuals with little or no experience with the cloud. Application stretching, for example, can allow the company to store data locally while utilizing analytical processing in the cloud.
5. For some industries, migration to a full public cloud is not an option due to regulatory compliance issues. In these situations a hybrid cloud may be the only option that will provide the cost and flexibility offered by the cloud while retaining compliance data behind a company’s firewall.
Businesses that connect to our VMware vCloud infrastructure and extend the capacity and increase the scalability of their existing VMware estate is really the perfect example of the hybrid cloud model in action and it helps address concerns some companies have about moving fully to a public cloud model, while at the same time providing a path to cloud computing that does not require a massive commitment of resources or a complete surrender of control over one’s data to an outside entity.
