I was wading through the confusion in this thread looking for this answer. The big benefit for me is that it is not virtualized. I can repurpose physical machines in my cluster quickly, by spinning up a different container. I don't want to run three VMs on one box, I want to run the same kind of node on thirty boxes. With Docker + Kubernetes (or Mesos), I can then switch these to another node type incredibly quickly. I can run the same container on AWS, VMWare, GCE, or Azure.

I guess most people don't need to do this...

[hosh]

I haven't needed that yet (not at the scale I am using), but that is exactly the use-case I am looking forward to.

I have a lot of interest in seeing our current devops tooling converging with AI/MI. I don't see that happening without something like Docker.
