Yeah, but it you start out using too much of the AWS tools, you're far more likely to get trapped in the AWS infrastructure and end up paying significantly more in the long term (which is what they want!). I'm not saying that AWS doesn't have useful features, but you need to appreciate the costs of these things before starting. If you need to spend a bit more time on devops in the beginning, then so be it. If you're starting a company, there had better be some good reasons behind using AWS, aside from "because faster iteration, developer time!".

Specifically - what AWS features do you find to be useful at the beginning? You seem to have some specific use-cases in mind. I'm legitimately curious.
