Though this comparison is really only relevant for a couple of machines. Beyond that, at this cost, if you pay AWS list prices "at scale" you're doing something very wrong. Don't get me wrong - I've frequently argued that AWS is price gouging and relying on peoples lack of understanding of how the devops costs of running your own works out, but it doesn't take a huge budget before this calculation will look very different (still cheaper to own your own, though).
