alt Hacker News> AWS has people working 24x7 so that if something fails someone is there to take action..
The number of things that these 24x7 people from AWS will cover for you is small. If your application craps out for any number of reasons that doesn't have anything to do with AWS, that is on you. If your app needs to run 24x7 and it is critical, then you need your own 24x7 person anyway.
All the hardware and network issues are on them. I agree that you still need your own people to support you applications, but that is only part of the problem.
