IBM has never stopped selling mainframes. One of the big reasons why finance transactions are still COBOL is IBM consultants insisting that a centralized mainframe is better than a private cloud.
I can search it, but do you have a description of what type of finance transaction are being processed this way still?

In our case, everything ‘core’: checking and savings accounts, loans and credits, credit and debit cards… anything requiring a sub-second response time while being bombarded with tens of thousands of transactions per second AND requiring strict ACID transactions end to end AND 24x7 availability with quick recovery in case of disaster.
Secondary stuff is being moved to other architectures. And new core stuff is being written in Java… and ran on the mainframe.

It's a niche market, but if someone wants total control, then you get a mainframe even if it costs more and is an inferior service to the cloud providers.
Cloud is proving itself more costly and error prone by the day. I’d opt for on-prem, fuck all that noise giving someone else the power
I mean... Everything is, really. I don't think it's a problem with cloud, I think corporations are slashing their workforce so hard they can't keep up the quality
Cloud's cute until there's a network outage.
…that nobody will buy because of retaliatory tariffs
