Clearly, there is a need for a baseline definition and a discussion of the many aspects comprising cloud computing.I believes that a detailed characterization of cloud computing must include three things:
1. The consumption model. Cloud computing offers a unique way to consume compute, network, and storage resources.
2. The services model. Cloud computing can be used as a platform for different activities up and down the technology stack.
3. The deployment model. Cloud computing is not a one-size-fits-all platform. Rather, there arenumerous ways to deploy and utilize clouds.
