Hybrid Approach for Cloud Computing Adoption
Concepts of private and public clouds came into existence when cloud computing was an emerging trend trying to lay its roots into the large scale enterprise’s IT environment. The multi-tenant model of public clouds succeeded in attracting numerous small-scale organizations, which found the CapEx savings and reduced development time as alluring.
But large-scale enterprises see the public nature of cloud as a potential issue for adoption. Moreover, the fact that the IT is out of the limits of their control further alleviates the threat to public cloud’s adoption.
With an aim to tackle the challenges of public cloud a concept of in-house private clouds caught pace. However though private clouds are supposed to emulate the public cloud functionalities, they introduce their own shortcomings of scalability and up-front costs.
Hybrid model combining best of both worlds can be a solution.
Hybrid be the way:
What can help enterprises is a hybrid approach that allows them to adopt the public clouds partially, deploying only those services which they see suitable. No doubt, the success of this hybrid approach is, defined by how seamlessly the underlying public and private clouds can interact and work together in unison.
One typical use case where the hybrid approach does sound beneficial is in making sure the performance is unaffected in case of sudden load spikes. Instances of same application can reside on both private and public cloud. A cloud integration manager directs the request to the public cloud the moment internal infrastructure underlying the private cloud fails to handle the increased load. This allows the limited usage of the massively scalable environment of public clouds. At the same time, it also allows enterprises to use their existing infrastructure.
Simple it may sound but..
Although this integration of public and private cloud looks alluring, it brings forth some of its implementation challenges. Moreover the basis for this integration is how close the private clouds can emulate the public clouds. As put forth by Google's
