Generally you're hitting the cheap part of your ops team. The rack and stack, and dc technicians. You start seeing the real savings when you move up to using higher services like managed databases, and analytics engines.
I think that's right. We tend to see fragmentation w/ our hybrid approach. Teams doing DevOps type stuff with VMware/vRA on internal hardware and also on AWS/Azure. "Customers" of each environment also tend to be different so priority conflicts arise.
Could be solved by more staffing, I suppose...
