So you’re recognizing that a bad command execution can exist in CDN or cloud provider, but where is your recognition of the tens of millions off bad command executions that happen in small IT shops every month?
I looks like you’re ignoring the practical realities that companies rarely ever:
hire enough support staff
hire enough skilled staff
invest in enough redundant infrastructure to survive hardware or connectivity failures
design applications with resiliency
have high enough rigor for audit, safe change control, rollback
shield the operations stupid decisions leads impose because business goals are more important that IT safety
All of these things lead to system impacts and downtime that can only come from running your own datacenters.
The cloud isn’t perfect, but for lots and lots of companies its a much better and cheaper option than “rolling your own”.
