1. Cloud Computing is a general term for anything that involves delivering hosted services over the Internet.These services are broadly divided into three categories:Infrastructure-as-a-Service (SaaS),Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS).The name Cloud Computing was inspired by the cloud symbol that's often used to represent the Internet in flowcharts and diagrams.

2. A cloud service has three distinct characteristics that differentiate it from traditional service.It is sold on demand,typically by the minute or the hour;it is elastic—a user can have as much or as little of a service as they want at any given time;and the service is fully managed by the provider (the consumer needs nothing but a personal computer and Internet access).Significant innovations in virtualization and distributed computing,as well as improved access to High-Speed Internet and a weak economy,have increased interest in Cloud Computing.
