My apologies is I misread what you said, it looked like your reply was to "anyone running their own cluster is insane" in the previous comment. And as I said, to me that means "on their own bare metal servers".

I'm talking about getting a Kubernetes cluster (of any kind really, but specifically on-prem) _integrated_ and doing useful things with existing legacy workflows inside your company using an existing infrastructure is a larger task than I see it made out to be.
