and for that reason zCX is very important for ISVs because it does offload to
Ziips, provides an open technology platform and for customers that do not have
vZM or IFLs we can deliver software easier using a familiar CI/CVD pipeline.
The elephant in the room is that almost all customers will have x86
platforms available and it's trivial to stand up VMs using automation
such as Red Hat Ansible. I suppose it comes down to politics again. The
mainframe folks at some sites may be determined to run everything on z.
That's not my experience with our customers who use our streaming
products. They all run Splunk, Elastic, Kafka stacks on x86 and there's
practically zero chance of them moving to z. I'm not knocking zCX. I
think it's a great solution and can see a lot of use cases where it
makes sense both technically and economically. I'm just highly dubious
that running medium/large distributed software stacks is one of them.

The z/OS version is not zIIP-eligible and is therefore running on knee-capped

fast (and SMT-threaded). The Linux for x86 version is also fast (and
hyper-threaded). Given this constraint, we try to put CPU-intensive activities
(such as code page conversion) on the faster-executing platforms.
