Cloud computing is a paradigm in which dynamically scalable and often virtualized resources are provided as a service over the Internet. It is gaining popularity in a variety of domains such as web hosting, enterprise systems, and e-commerce sites. Each server can run one or more applications and application components may be distributed across multiple servers. In general, a cloud can contain several data centers in different geographical locations. Furthermore, each application sees dynamic workload affected by incremental growth, time of day, and flash crowds.
