Cloud Computing, originated from the ideas of concurrent processing from Computer Cluster. It has enhanced the established architecture and standards of Grid Computing with the ideas of Utility and Service-oriented Computing. Computing through Cloud supplements a business model as a form of X-as-a-Service where X stands for Hardware, Software, Developing platform or some Storage media. End-users can consume any of these services from providers, pay-as-you-go basis without knowing the details of underlying architecture. Hence, Cloud offers layers of abstraction to end-users and a scope to modify the application demand for end-users, developers and providers.
