Over the past two weeks I’ve spent some time with friends who are investigating Amazon’s EC2 service.  I must say that I’m very impressed.  Essentially the service allows you to run a virtual computer.  You can then add and remove horsepower via web service calls, and all you pay for is the uptime per hour, and bandwidth.

I believe the service is either running Xen or is based off of it. Either way, what they have done with it is truely amazing.
