a while ago there was a bit of fuss about Windows having introduced something very similar to containers... in the sense that you could spawn small windows "instances" (I don't remember the correct name) and run applications in there. similar to "containers" (as a bunch of namespaces) rather than jails rather than zones.

IIRC Kubernetes could have windows node as well?

EDIT: yep... https://kubernetes.io/docs/concepts/windows/intro/
