Just wanted to chime in and hard agree on this. I remember the world where people were trying to build things like kubernetes before it existed. There was a period where enough people had left google post ipo to realize that they needed something like borg but nothing really existed like that outside of elgoog.

Twitter had Aurora, then elsewhere mesos and mesosphere popped up and it seemed like there were going to be about 100 different frameworks until Kubernetes dropped and basically ate the industry alive. K8s feels pretty stable from where I’m sitting.
