I know what Sysplex is, and it is decades older than z16.
Sysplex is a software construct, not hardware, although certain hardware is

How could you not find official references when so many people are infuriated.

Kevin’s note is a great summary. FWIW, years ago when I worked for IBM (early
2000’s) we met with RedHat. During the introductions someone from IBM referred
to them as an Open Source company. One of the RedHat execs corrected them and
said, “We are a commercial software company that uses

z\OS containers being crucial? Absolutely. Some z\OS, DB/2, etc. upgrades
require applications, subsystems, LPARs, Sysplexes, etc. At a certain stage
before proceeding to the next stage. Hopefully these requirements can be
limited to one or a small subset of containers.
On Wed, Jul 19, 2023,
Has anyone considered that z/OS is knee-capped so it only runs on GPs? Are we
suggesting that people will buy GPs at 10 times the price rather than IFLs or
zIIPs just so they can run z/OS under Linux?

I feel like I’m arguing with the same people who thought the mainframe was
going to be obsolete by Y2K. Very poor fit NOW. In 10 years, perhaps not.

Just lifting and shifting distributed tech onto mainframe, with no
consideration of the extreme complexities is very wasteful.

Bill, Bill, Bill. Stick to stuff you know something about. IF quantum
computers ever become realistically powerful, they will have VERY specific
uses. They are not suited for general-purpose computing. Nobody even

research
Here's a dumb and bold prediction - the guts of RHEL (CoreOS) will be laid bare
within zOS.
USS becomes LSS. zOS native containers are actually normal containers that you
see in the linux world.
DSFS and zCX end up helping to blur the boundaries between zOS and LSS.
zOS is not going away. But we
