This level abstraction seems unnecessary. We need to just let-go of the concept of physical or virtual hosts. A machine should boot and join a cluster, advertising its capabilities (ssd drives, gpu's, enhanced networking, it's availability zone or region, etc...) and you should never need to think about that stuff, period.

I don't care how many devices/segments/nodes/slices/dynos/widgets are in my cluster. I care that I have X GB of total memory and Y cpu's. I want to check a box to make an app or service highly available (on more than one node, and in more than one zone) and Ronco™ set it and forget it.

Everything else is just noise.

I love the ideas behind Kubernetes and Fleet/CoreOS (and this) but everyone is SO excited about these low level technologies that have yet to be composed into beautiful experiences.

A tweet from Kelsey Hightower sums it up perfectly:

    It's going to be nearly impossible for people
    to evaluate and chose a container management platform
    during the gold rush.
