Yeah I mean sunk cost fallacy, right? If you’ve already hit critical mass in AWS of course you’re going continue investing in it.
If I were to be CTO of a brand new company today, I’d probably just colocate my own servers with K8S. Much cheaper and much lower latency. 2x 1TB RAM servers with 3x 8TB high speed U.2/U.3 drives each would last years.
(1) They will usually notify a few minutes (or hours) in advance, and (2) it would take a few minutes to spin up and set up a new VM to replace the old, without leaving your terminal.
