Though for 80-90% og cases out there you seriously don’t need k8s, and when the small internal IT dept that used to “manage” a dozen virtual machines starts talking about “need to keep up with the times and use new tech” what they are really saying is “let’s gamble infrastructure stability on my personal self education in k8s for my next job” and it’s perfectly reasonable to give them a hard no.
Indeed, the problem of just saying "you don't need k8s" is you may accidentally invent an even worse in-house version of k8s.
