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've been cycling around that wheel for a while.

If there's any difference now versus the past, it is that I think right now pretty much every point on the wheel is available quite readily now. If you want a more "rudimentary OS" you don't need to wait for the next turning of the wheel, it's here now. Need full VMs? Still a practical technology. Containers enough? Actively in development and use. Mix & match? Around any sensible combination you can do it now. And so on.
