Thanks. I agree that lift and shift never happens easily in real life.

That being said, why would I not use the actual free upstream Kubernetes for my on-prem distribution ? (with the help of one of the thousands installer out there like kube-adm, kubespray, etc).

What I have seen working with Kubernetes for quite a while, is that the lowest common demominator is the YAML definitions for your workloads (what you want to run on your Kubernetes cluster). Those should be portable accross any Kubernetes distribution, on-prem or on the cloud. As far as I can tell, today this is already the case.

Is the benefit in this case that you can use the Google ecosystem for logs etc ?
