Cloud computing is simply a set of pooled computing resources and services delivered over the web. When you diagram the relationships between all the elements it resembles a cloud. Cloud computing is often provided "as a service" over the Internet, typically in the form of infrastructure as a service (IaaS), platform as a service (PaaS), or software as a service (SaaS).
As a Cloud computing customer, you don't have to raise the capital to purchase, manage, maintain, and scale the physical infrastructure required for enterprise applications. You just pay according to actual use as opposed to conventional processes where you have to have a complete infrastructure whether you use it or not. Hosted processes are extremely cost effective.
