Definitions of what constitutes a private Cloud are suspect; meanwhile public Cloud adoption though slow is picking up pace
When is a Cloud not a Cloud? Well, when you are talking about private Clouds, many experts feel that the deployment of private Clouds in India isn't all that it is cracked up to be. Basically, server virtualization has picked up in many pockets but a virtualized setup isn't a private Cloud unless and until you add orchestration and self-provisioning. Then there's the question of exactly how much control Indian CIOs and IT managers are willing to relinquish and the bigger question of if the business users really want that control.
Self-provisioning, from the vendor side, is being sold as the answer all of a business' woes. If the business unit heads are IT-savvy, then yes, it could be a powerful enabler but if they aren't, then it could be disastrous. Moreover, who will ensure that self-provisioned resources aren't wasted. The more I think about this, the more I feel that a strictly defined private Cloud makes sense mostly in a test & dev environment where developers need to provision and release resources rapidly. In a conventional business unit, IT provisioning probably doesn't need to be quite as rapid. More details here
