How Big Is VMS?

Is there any reason to use VMS today other than for existing applications that cannot be migrated? I've heard its reliability is legendary, but I've never tried it myself. The 1 year licensed VM seems excessively annoying. Is it just old and esoteric, or does it still have practical use? At least with Linux, multiple vendors release and support distros and it is mainstream, whereas with VMS, you'd be stuck with VSI.

I was actually surprised to see that there's been a release in the last 12 months - I had thought it was dead.

I used it extensively in the late 90's early 00's and really liked it. As a newb sysadmin at the time, the built-in versioning on the fs saved me from more than one self-inflicted fsck up.

I can't imagine there would be any green-field deployments in the last 10 years or so - I'm guessing it's just supporting legacy environments.

HP tried to kill it. Somewhere in the neighborhood of 10 years ago they announced the EOL. This company - VMS Software Inc (VSI) was formed specifically to buy the rights and maintain/port it. So you have an interesting situation.

Old VAX and Alpha systems are supported, supposedly indefinitely, but if you have an Itanium system it has to be newer than a certain age. HP didn’t sell the rights to support the older Itaniums, and no longer issues licenses for them. So there is a VMS hardware age gap. Really old is ok. Really new is ok.

It's now ported to x86 as well, so you can probably just order a Dell box and install OpenVMS on it.

HP box. It is a former HP product.

Version 9.x has been out for 5 years, stable for 3, and primarily targets and supports hypervisors. It knows about and directly supports VMware, Hyper-V and KVM.

So, yes, get a generic x86-64 box, bung one of the big 3 hypervisors on it, and bang, you are ready to run VMS 9.
