Ah, that explains why IBM bought RedHat. Or at least one reason for doing so.
replyI'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.
replyIs that in addition to mainframes or for completely replacing them?
replyProbably both, to respond to the risk tolerances of any given org.
replyBoth
replySome 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%).
