That's great, good on you.
I joyfully anticipate your report on replacing banking and insurance mainframes with "non-mainframe strategies to zero-downtime, relative to the workload"
Or not. If banks, insurance companies, airlines, and others with a nine-nines uptime requirement could replace their mainframes with "non-mainframe strategies", I'd be happy to read about it.
Really? You don't think banks would have moved off the mainframe world if they had been able to find a replacement that was just as reliable for the same price or cheaper?
It's been decades, and it's never happened.
"The vast majority of no-downtime experiences in the modern era don't have mainframe involvement."
LOL. You have no idea.
