I'm trying to understand why people are spinning up so many k8s clusters that they need a tool to do it for them?
I have one. And it's managed. I don't think there's significant cost savings to going unmanaged, but maybe. Even so, why would I need a ton of them?
It's applied big brain memetics. k8s turned pet servers into cattle. People then do the next step and want to treat their clusters as cattle as well. Also it has a bit of the "can it run DOOM" vibe to treat whole k8s clusters like this.
You're cool if you manage your own K8S cluster.
