I take it that ec2 is simply too complex for you? (Their payment system is almost impossible to calculate beforehand). If you need something much more simple you can get a vps, cheaper than a dedicated server. If your after a service that's simple and great or amazing to use, heroku provides that. They take away the pain of having to deal with any servers, you upload your code and specify how much computing power you will need by ramping up the "dynos" on your project. 1 dyno = ~512mb vps. They let you use 1 dyno per project free in the free tier. Only bad thing about them is they don't support a wide range of languages/programs, and their routing is bit a questionable but not too bad. I use them for loads a project, specifically node.js projects.
Nope, not complex. I have an automated setup to kick-off processes on 50-500 instances simultaneously. What I'm looking for is something that is less expensive than EC2. It might be they are as cheap as it comes, but I figured I'd ask the community on this and see where it goes.
