Kubernetes has a fairly soft tenancy model, so in practice, multi-cluster is becoming a big deal, despite the cost in utilisation efficiency. Various attempts are being made to recover the utilisation efficiencies, such as Virtual Kubelet or Project Pacific. I think that the original sin of Kubernetes was the lack of a firm, first-class, top-down, mandatory access control model of tenancy. Disclosure: I work for VMware, which is responsible for Project Pacific.
