Amazon has a number of Cloud offerings. The Amazon EC2 (Elastic Compute Cloud) is an offering that allows users to request "virtual machines" in the cloud. Once the request is met, the user can "provision"these virtual cloud servers to run any software they want. This is completely dynamic in the sense that the user has control over how many virtual instances he wants to provision and run at a particular point in time. The servers can run anything from OpenSolaris, Linux to Windows Server 2003.

Other services that Amazon has include S3 (Simple Storage Service) - a service that lets users or applications use unlimited storage for their files and SimpleDB, - a distributed database system that can be used in conjunction with S3 and EC2. All of these services are available through programming models to enable end users the ability to use them in their own applications as well.
