To use Amazon EC2, you simply:

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.
Use Amazon EC2 web service to start, terminate, and monitor as many instances of your AMI as needed.
Pay for the instance hours and bandwidth that you actually consume.
