It's not that evil. The first time used AWS, I really enjoyed the power and easy to set up the whole system from scratch everything (network, servers....) If it's on-premise, it'd cost a ton of effort of a lot of ppl. AWS is not that's hard, the console + UI is user friendly and they have a great document site so you don't really need to get these AWS's certs (I had one about 3-4 years and honestly the information in these tests are not helpful, rarely 1 people need to remember a lot of details in 20+ services of amazon, whenever you want to use one just start reading document about it). A new service from AWS - that's great. At least that is a new option for end user.
