And a lot of companies understand that #RedHat is where you get the help to run that #OpenSource stack in a way that lets you focus on the things you run on top of it. https://www.redhat.com/en/blog/red-hat-leading-enterprise-linux-server-market
@jwildeboer Christ, the Enterprise Server market's changed a smidge since, say, 2004.
Proprietary Unix is gone.
Likewise Anyone Else (DEC, VMS, Acorn, etc.).
Linux and Windows. Mostly Linux....
@dredmorbius Yes, 15 years ago the world was a different place. But I already said back then (I got hired by Red Hat in 2005) that soon(tm) the fight in the Datacenter will be between Linux and Windows. And that Linux will win. And that was before cloud, microservices, containers even were a concept. It’s all about #Open. Open will win.
@jwildeboer Oh, I (or a past me) was saying much the same thing. It's just seeing the actual instance-share that's pretty stunning.
One lesson I've learned that Past Me might have found useful: arguing against naysayers is almost entirely useless. Truth will out. Stating your own piece, or far better, simply, effectively, and inexpensively demonstrating capability, is far more useful.
@mathew That should still show up in server sales, though, and there's not much room within the chart Jan showed for that.
I also have a *really* hard time believing that all the government, insurance, healthcare, and banking mainframe systems have been ported over.
Though I would not be entirely unpleased were this to be true.
(I could spell "ISPF" and "JCL" at one point in my life. Also EVE and DCL....)
Many banks and airlines still run their old systems. SABRE is still around, apparently AA's 2009 attempt to get HP to write a replacement failed? I gather about 60% of SABRE has been migrated to cloud servers, but there are still mainframes. I believe the Federal Reserve still uses IMS, as I'm sure many banks do, and that dates back to 1966.
(I have no inside info about any of this.)
