k8s is an industry standard currently, but it is not great. The lack of available free/open tooling to set up and manage them (the cluster) properly seems to indicate that it is also a way of selling it (cloud). Meaning that if you want to use k8s you have to go with the large cloud providers, otherwise your life will be painful.

I for one am patiently waiting for more innovation in this area and seeing that there are companies that try to disrupt/improve it makes me hopeful and I appreciate it.
