Maybe I don't fully understand DC/OS then. I was under the impression that DC/OS was simply a distro for Mesosphere. But your comment make me think that either my understanding is incorrect or else DC/OS has become something more than a Mesos distro. Could you elaborate? Thanks.
You're correct in that GCP runs k8s in VMs, DC/OS doesn't. What's similar is that there's a resource manager underneath - Borg for GCP, Mesos for DC/OS. They serve similar purposes like resource management, isolation, and operating the services on top.
