It seems absolutely within amazon's technical ability to allow you to prepay for usage, and then evaluate your use on a per-hour basis. I have a side project that uses AWS at the moment, and while stuff like serverless RDS instances are really cool, it scares me that somehow amazon is going to have a bug which empties my checking account. I've read as much of the documentation as I can find and have done everything I seem to be able to to prevent this from happening according to AWSs documentation, but it sill worries me. In fact here is a banking feature I'd love to see: per merchant daily spending limits. I would love to be able to tell my bank that amazon is allowed access to up to $20/day or something of money until they get rate limited and I have to intervene. Uh oh I better stop before I start advocating for the blockchain, haha
