Imagine server that has been up for decades. It can remain live through OS upgrades, hardware upgrades and I believe even architecture changes. It's like places that use mainframes it's probably not a good idea to build a new bank on mainframes but if you have one it's far less risk to keep the mainframe than rewrite everything. OpenVMS has some very unique features but truthfully it's most valuable feature is it runs the software they have.

But that's the thing: places which fit those requirements usually run some IBM solution (AS/400 and the likes). I've never encountered VMS in production before, so I'm really curious to some concrete examples of companies using it.

  I just got paid $6784 working off my laptop this month. And if you think that's cool, my divorced friend has twin toddlers and made over $9k her first month. It feels so good making so much money when other people have to work for so much less. This is what I do,====http://bit.do/dnRs5 http://bit.do/dnRs5

    I've made $64,000 so far this year working online and I'm a full time student. Im using an online business opportunity I heard about and I've made such great money. It's really user friendly and I'm just so happy that I found out about it. Heres what I do, •••••••http://bit.do/www-joinmate2-com http://bit.do/www-joinmate2-com

  VMS was widely used in healthcare.

  I used to work as a software developer in the UK insurance industry, and I can tell you that we (and hence several of the insurers/brokers we dealt with) used OpenVMS. In contrast to some of the other comments here, we weren't using it because moving to another OS - or architecture - would have been a pain. In fact, our software originally ran on x86 machines at some point in the distant past, before we migrated it to OpenVMS relatively recently. I don't know why OpenVMS was given preference over GNU/Linux, *BSD, or Windows; I'm guessing that the technical managers above me had their reasons, but I couldn't say what they were. I left that job a few years ago, but I think that they did intend to eventually phase out the VMS systems as our new, GUI-based product slowly replaced the older text-based one.

  We use it at our company (financial software). One of the reasons being that the code is older than Linux and VMS was a good bet at the time. We have almost entirely moved away from it and onto Linux but considering the decades of code and systems built on and around it, it is truly a monumental task to move off VMS while keeping a system used by very high paying clients running smoothly.

  We used to have a CNC machine controlled by a VMS box. I almost burst into tears when it was unceremoniously decommissioned while I was on holiday - that thing had been up for more than six years! (Which is not at all uncommon in VMS circles!)

  Some cable companies run it

  I haven't used other mainframe solutions, but one of my favorite features of VMS is logicals. Logicals are environment variables backed by a clustered key value store that's safe to use for distributed locks. Logicals appear to your process in a hierarchy of tables that inherit from one another, by default you have: job (shell subprocess) > process (shell session) > user > group > system (node) > cluster. You can also build your own tables stored with which ever chosen locality (system, cluster, etc) in the hierarchy. Meaning if you follow "12-factor" design, well it didn't have fancy name then, you could do things change configuration cluster wide in an instant.
