I think it's incentives. Working with AWS is good for your resume. It's also a responsibility thing. If AWS is down then it's Amazon's fault. If there's a problem with your physical server, then it's your problem.

A broader thing here is -- and you may also notice this trend in software -- employees are incentivized towards complex solutions, while business owners are incentivized towards simple solutions.
