> Most things don't need autoscaling
Correction - most things can't be autoscaled. I'll eat my hat if more than 25% of existing k8s clusters can even autoscale. Most will use PVC's and other stupid overengineered hoops to bind CPU to specific physical storage.
TLDR - k8s is just a painful enterprise thing to justify ops budgets for BigCorp. (Presumably, to counteract the fact that much of that budget went into "the cloud" lately.)
