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.

And number of those has nowhere to go but down too. There is no growth in either of those, because everyone who will at some point try to get rid of them. Not all, not immediately, but the ultimate trajectory is down.

People are still setting up machines by hand, then leaving companies without documenting what they did. The whole "infrastructure as code" is a fantasy at most real companies.

Best of luck. Without revealing any commercially sensitive information it would be fun to know what the age of the oldest VM running is. Windows 2K? RHEL 4?

(As an end-user sort of person, I get a strong smell of Bladerunner from this kind of thing, where you can see old PCs in the background on top of decks with cables running out of them).

As I said in another thread, Win95 and RHEL 3 are the oldest we've come across recently. Guests of this sort are not converted, they're copied and run using emulated devices (IDE/SATA, e1000 network etc). We help customers as best we can but don't support these cases.

Usually the story is they're running something like CNC control which originally ran on baremetal, then got virtualized onto VMware when the hardware died (possibly using VDI to make it appear on a terminal close to the machien), and it's still doing the same thing effectively today.

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

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