Companies spend an eye watering amount of money on AWS relative the underlying hardware cost. There's definitely a market for something like a mainframe that runs K8s, Postgres, Redis, and the like where you buy once and then run forever.

I don't know if it's true or not but it seems like our AWS bill is something like paying the full purchase price of the underlying hardware every month.

AWS supplies a significant portion (was it something like 50%?) of Amazon's overall profits.
