a single cluster supports approx 5,000 nodes, 110 pods per node~

The estimated maximum single cluster is 300,000 containers.

That's pretty medium, I've ran more than a million processes before, and nomad has 1million containers as its challenge https://www.hashicorp.com/c1m

borg can handle this easily.

I don't know anyone running 5k node K8S clusters. That said, borg (as an end user) appears to just keep scaling, but it uses a different model and makes different assumptions than K8S.

Sure. Most people have more clusters before they hit 5k nodes on a single cluster.

But I’ve been in situations where it would have been worthwhile. I’ve been in situations with 30,000 machines that needed to be controlled. Splitting them out into very many clusters would be a lot of wasted overhead in configuration, administration and because you lose nodes to masters.
