“Amazon EC2 allows you to set up and configure everything about your instances from your operating system up to your applications.”“provides the equivalent of a system with a 1.7Ghz Xeon CPU, 1.75GB of RAM, 160GB of local disk, and 250Mb/s of network bandwidth”
You basically create your own Amazon Virtual Machine Image and upload it configured the way you want.
