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.

There was a multi-machine single-Linux-kernel-instance distro many years ago called Kerrighed. The company behind it died unfortunately so it hasn't kept up with Linux kernel patch rebasing. It offered a "view of a unique SMP machine on top of a cluster of standard PCs".
