EC2 works for a lot of models, but one that it does not work for is small traffic apps that need to be available 24/7. If you have a small instance (AWS term) running full time with a fixed IP, it costs about $75 a month. If you turn it on for 2 hours a day, it costs about $15/month. A large instance is about $325. Now where it gets interesting is if your app needs a large instance, but only run a few hours a month, you might be able to run a micro instance that is set to start a large (or ???) instance on demand, and run the whole thing for peanuts.
