To extend my comment: notice how the tech on the left side was/is usually backed up by companies or corporations while the tech on the right side usually is not. I think this is just a natural flow of software: some piece of software emerges for the benefit of a big corp disguised as open source… and suddenly everyone uses it. It takes some time to the “internet community” to come up with something better and less tied to any company in particular. It’s a win for everyone: Google is having his piece of cake with GKE now, the community thanks the effort and will use k8s as an inspiration to make something better.
