Cloud Computing is more than just a utility cost reduction exercise of your IT storage and computing assets through subscribing or purchasing to an on-demand, pay-as-you-go model. Cloud Computing is evolving into an ecosystem of services from storage, computing and network infrastructure to impacting the integration and application software to transform the business processes and market service models.
