I've been meaning to write that blog post for a long time. In broad terms, EC2 is the perfect fit for a service like this, that needs to run something like 100 hours of computing each day, but needs that all to happen during a 3 hour window before Europe wakes up in the morning. It's even more fun when something breaks and I get to spin up 200 machines in one go. For like ten dollars. I use something like 8 different AWS services for various bits of the thing. Everything from computing to storage to queueing & mail. I even used them for payment at one point. I'll try to get that writeup out the door.
