My money’s on Conway’s law. There’s a hardware team that’s in charge of the hardware, and they need to orchestrate ask the nodes, then there’s the openstack team that’s their customer who’s in charge of providing a cloud-like environment to the rest of the company including windows VMs, then there’s an applications kube team that provides kube for services that run on kube, with finally kube-ized applications teams that run on the very top.
