Amazon goes to the extreme of putting its own custom firmware on switchgear because the choices that vendor makes in theirs doesn’t align with their objectives.
I don’t think AWS is blowing up a vendors phone when something goes wrong in one of their facilities.
That's some magical thinking, thinking that you don't need hardware people because you wrote some software.
All the same gear is still there, its control functions are just ceded to Amazon panels. And integrated to the point of even removing some PLC like devices.
