Create an Amazon Machine Image (AMI) containing your applications, libraries, data and associated configuration settings. Or use our pre-configured, templated images to get up and running immediately.

Upload the AMI into Amazon S3. Amazon EC2 provides tools that make storing the AMI simple. Amazon S3 provides a safe, reliable and fast repository to store your images.

Use Amazon EC2 web service to configure security and network access.

Choose the type(s) of instance you want to run. Start, terminate, and monitor as many instances of your

AMI as needed, using the web service APIs. Pay for the instance-hours and bandwidth that you

actually consume.

data ,software and service on demand the vision -- reduce the cost of computing,

increase reliability, and increase flexibility by transforming computers from something that we buy and operate ourselves to something that is operated by a third party.
