I was managing k8s cluster for a CDN, we had small clusters in each of our ~120 datacenters around the world, plus a number of larger clusters in our redundant back offices.

We couldn't use managed clusters because these were running on our own hardware, and they needed to run on the same infrastructure as the CDN itself.

The point of the local clusters was for workloads that needed to run in each data center, and then multiple clusters in the back office for both compliance and operational reasons.

I would not have used a tool like this, though. We used Rancher to manage our clusters.
