I whole heartedly agree. But I think, somehow, IBM is still gun
shy because of DOJ anti-trust actions they've had to deal with.
Anyhow, having done capacity planning with z/VM and linux
images.... I look at this going off to cloud differently. It is a
big cost that only gets larger.
So we all retire and the new kids get to figure out all this code
we wrote where companies allowed documentation to get trashed,
not realizing that they needed to capture it... I say this
because I'm being contacted now to help companies document all
their obsolete COBOL code, and missing source... You would have
thought they would have learned from the Y2K problems.
Hey Steve Beaver, what do you think someone is worth that can
read all that code and run book doc and explain all the
interfaces that DON'T exist outside of z/OS?--

This is a marketing opportunity. IBM should contact Google. IBM should
suggest a parallel test with returned hardware (z16, z15, z14). Convert
their stack to run in a Linux on z image, then duplicate a portion of
workload to the z?15? with limited processors and see how they run.
Gradually increase the workload until the z has delays the up the number of
z processors. Do workload balancing, shifting between images when workload
changes, etc, all while documenting workload, power use, costs on newer
models, etc.

Well, I got connected to AI, and got into a bit of a chat.
Bottom line, all things considered, cloud will cost more over
time than using mainframes and merging linux workloads under z/VM.
But sales people revenue off of modernization off to a cloud and
not getting all the speed and processing a z/Arch machine can do
on the MVS side and the Unix System Services side.
Things go in cycles. Wonder if I will live long enough to migrate
back to z/Arch or whatever it will be called with the next
generation...

I don't have pilot.... What answer would one get to a question
of which is faster (second question more efficient) a 4 CORE
(pick the CPU CHIP) or a z/1x with 4 CPs?
I just wonder what answer one would get....

If AI correct answers was a standard, "I'm sorry Dave" would
be the most common answer. Better an incorrect answer than no
answer at all.
I asked copilot "which cpu has the fastest single core
speed?". It did not answer IBM TELUM where the instruction set
and IBM boasts each performs 10X better than any other CPU
core while running Linux.
I asked copilot "is el capitan supercomputer a server farm?"
and it replied, "not exactly". Copiliot ignores that el
capitan is built using 5,000 blade servers, each running Linux
that boasts a network speed of 12tb/sec. "server" is literally
in the name.
