Cloud Computing: Myth or Legend??

Is cloud computing real? Is it just another name for the public internet? Is private cloud just another name for a data center. Or is there really more to it than that?

Cloud computing is real. It enables services on demand to a wide range of devices such as PCs, notebooks, tablets, smartphones, etc. These services are delivered via a shared and scalable pool of compute, storage, and networking infrastructure. Many common online applications such as email, search, and social networking are delivered via the "cloud".

Cloud computing is changing business and infrastructure paradigms within IT more than any other issue.
