A Cloud is a set of machines and web services that implement cloud computing. Users of a cloud request access from a set of web services that manage a pool of computing resources (i.e., machines, network, storage, operating systems, etc). It eliminates the need for organizations to build and maintain expensive data centers plus software costs, too. This paper gives the basic concept, defines the terms used in the industry, and outlines the general Architecture, SaaS, PaaS and IaaS of Cloud computing. It gives a summary of Cloud Computing and provides a good foundation for understanding. Cloud computing is a better way to run their business. Instead of running their apps on their data center, they run on a shared data center.
