None of this is difficult to do or automate, and we've done it for years. Kubernetes simply makes it more complex by adding additional abstractions in the pursuit of pretending hardware doesn't exist.

There are, maybe, a dozen companies in the world with a large enough physical footprint where Kubernetes might make sense. Everyone else is either engaged in resume-driven development, or has gone down some profoundly wrong path with their application architecture to where it is somehow the lesser evil.
