Red Hat OpenShift (IBM) is what a lot of banks have settled on. Red Hat went all in maybe 5+ years ago in capturing those institutions.

Ah, that explains why IBM bought RedHat. Or at least one reason for doing so.

I'd imagine close to 95% in the US, if they're running important workloads on prem on Linux, it's on RHEL. A staggering number of VMs and bare metal.

[esseph]

(Clarification: I'm not saying 95% of all US company Linux workloads are RHEL, not even close.

I'm saying a huge percentage of high criticality (risk of loss of life / high financial risk) are, simply because of support and the name.)

Exactly. The exact opposite of the people flogging internet widgets running on a bunch of AWS instances running Arch/Ubuntu/Cheap distro of the week. Unfortunately that contingent is massively over-represented here on HN.

[Bigpet]

Is that in addition to mainframes or for completely replacing them?

[esseph]

Both

Some stayed at on prem, some pushed code to mainframe VMs in the cloud, some went to OpenShift (mostly on prem from what Ive seen, probably 80-85%).

Probably both, to respond to the risk tolerances of any given org.
