The way the EC2
service is used is bascially linux boxes on demand. Typical appl architecture are web servers,
database servers, app servers—you would build up machines as you normally
would on a linux box and then we provide tools to allow you to shrink-wrap
your machine images, store them on S3.
The way Ec2 works is you can make a web service call and say I need 25
of those AMIs up and running—within 5-10 minutes you are up and running. Under heavy load allocate more, if load
drops off you can scale back. You
don’t pay for boxes sitting idle and you can handle any spike. |

It’s a medium weight
server (it’s an instance), hardware underneath are comodity servers. EC2 uses Xen for virtualation layer. Anythign that runs on Xen runs on EC2. |
