You're gonna get some "git gud scrub" responses, but really the high cost is just what everyone discovers; it's just your turn.

In both my jobs I went through the eager take-up of (pub) cloud and saas schemes, and then the eventual 90% repatriation of compute.

Turns out it's still cheaper to run your own team with your own priv-cloud gear in a DC. Like, usually by a good amount. Yes, Virginia, even if you're a black belt cloud master of saas (which is just sales and kool-aid).
