He’s been remarkably transparent with changes he’s made to make running it more cost-efficient—and since he’s running this in a personal account, this is real money rather than AWS Credits (motto: “Like Bitcoin but less obnoxious”). The entire system is open-sourced and, after a bit of bargaining, he let me into his account to take a look at the bill. In this post, we tear down what he’s running, how it could be optimized, and what it takes to get there.
This is a microcosm of what I do; my actual clients have bills many times this size but they’re understandably reticent about letting me dissect their bills in public.
