Both sides need to be doing this. So many un-cited "AWS is cheaper overall" estimations, with hand-wavey "but you have to hire more IT staff" as their justification. Plus, articles which do the TCO calcuations (there was one recently that pointed out a 200% premium for AWS) are still derided because people really prefer to argue with their feelings on this topic. We get it, you don't want to run your own infrastructure. How much is that distaste worth to your company?
