Thanks for this shot of nostalgia that is rushing through my brain. Yes, I remember IPL from z/OS, working with RACF (Resource Access Control Facility), LPAR (Logical Partitions), and the complexity of Parallel Sysplex (clustering) all leading up to running COBOL and PL/I applications mostly for banks. The TN3270 terminals, and the wild hacks of writing Assembler macros to translate those TN3270 inputs and outputs to a webservice :-) I have never worked with the Power systems personally, but heard a lot of good things about it. It always felt like IBM enterprise stuff that $$$$ heavy are in a world of its own completely disconnected from people who cant think in that much $$$s.

Licenses for even the most trivial of software cost literal fortunes. It's just that these systems process billions of software and run millions of lines written decades ago. The cost is a mere blip.
