No one's going away from VMs any time soon (if ever). More than half of the workloads we see being migrated are Windows. Many more are odd/ancient RHEL versions running some very specific software where the manufacturer won't offer a newer version / went out of business / the guy who set it up left and no one knows how it's configured / it works and we never want to touch it again.

IBM’s mainframe business is also large and highly profitable.

It’s not growing in any meaningful way relative to other technology businesses.
