> The optimizations are no doubt impressive The sad thing is that the things they discuss like monitoring and optimizing slow queries have always, until recently, been baseline competence. It's only recently that the universal answer to something being too slow is to simply spin up another dozen, or heck make it two dozen, cloud instances to compensate. > Even if their DB infra was only half as efficient as it is today, their costs would increase by a whopping $8000/yr. I think the interesting comparison is not so much the same team doing things slightly less efficiently, but comparing to the average status quo in the industry. So many companies are spending $100K+/month (month not year) on AWS costs to run very tiny minimal loads due to the attitude that efficiency never matters, just spin up more instances. Pretty soon you're talking real money. And by the time the CFO starts screaming, it's very difficult to go back to a more sane infrastructure.
