Kubernetes is kind of the intellectually honest, logical end point of this stuff.
Kubernetes is an incredibly useful tool, but it needs at least one layer of abstraction (possibly multiple) on top of it to make it useful for the typical company that isn't doing anything out of the ordinary.
However, Kubernetes is more a primitive for infrastructure rather than a tool to build automation workflows for software teams. Our focus is to complement teams that may or may not choose Kubernetes.
