I literally don't know of any large companies moving away from virtualization to bare metal. Where is that information coming from?

I know of some that are deploying some things back to "bare metal" if that's what you want to call containers, but even in those instances, it's a very, VERY small subset of the larger environment.

I do know a few companies are using tools like OpenStack Ironic to do "Metal as a Service" - basically using a full machine like a VM.

That said it is usually deployed beside a cloud like thing, and only used for select workloads.
