I'm starting to see a pattern here. This describes a technology that rapidly deploys "VM" instances in the cloud which support things like Lambda and single-process containers. At what point do we scale this all back to a more rudimentary OS that provides security and process management across multiple physical machines? Or is there already a Linux distro that does this?

I ask because watching cloud providers like AWS slowly reinvent mainframes just seems like the painful way around.

We were working on this at CoreOS before Kubernetes came about – called fleet https://github.com/coreos/fleet. Distributed systemd units run across a cluster, typically running containers or golang binaries with a super minimal OS underneath. I always thought it was cool but it definitely had its challenges and Kubernetes is better in most ways, IMO.
