Not all data can be stored in public clouds for reasons of security, and private clouds are expensive. A via media is the hybrid cloud that allows you to categorize your information in order of importance and ensure that the most mission-critical information is stored in private repositories and public spaces are reserved for the “not so critical” information of your enterprise.
But, while the concept seems fairly simple, the actual implementation can be harrowing. Most organizations assume that hybrid clouds can be created by offloading some of the data and the applications to the public cloud and preserving the more important information and applications in private repositories. If you look at the process with a little more attention, you will understand that what you are really doing is creating a patchwork of technologies that may or may not work comfortably with each other! It is important to approach the issue of hybridizing your cloud with more sophistication.
Hybrid clouds span an entirely new universe of computing. Cloud bursts from private clouds to public clouds will not solve the problem of the enterprise looking for seamless integration of clouds. The boundaries have to be permeable and applications must have the capacity to shuffle seamlessly between the public and private areas of the computing universe without compromising security or creating compatibility glitches.
Hybrid clouds may take advantage of virtual machine probabilities, session management and other related computing developments to deliver data from public and private computing areas as part of the overall computing strategy. This is a complex technical problem that must be examined, evaluated and tailored to meet the needs of the specific enterprise.
To conclude: The roadmap to hybridization of your cloud must be well charted. That is your key to success. You must understand your IT architecture and application needs. The design of the applications and the deployment of workloads will be completely different in the hybrid situation. You must determine which of your applications are suitable for the public cloud or private cloud and take in to consideration factors like demand variability, high availability, response times and security or privacy requirements.
You must also take into consideration other relevant factors in the hybridization process such as integration of cloud APIs, the identification and installation of the management platform that will be used to monitoring and managing the environment and the deployment of highly specialized experts in virtualization and server management.
