One thing I learned when I started learning Kubernetes is that it is two disciplines that overlap, but are distinct none the less:

- Platform build and management - App build and management

Getting a stable K8s cluster up and running is quite different to building and running apps on it. Obviously there is overlap in the knowledge required, but there is a world of difference between using a cloud based cluster over your own home made one.

We are a very small team and opted for cloud managed clusters, which really freed me up to concentrate on how to build and manage applications running on it.
