I suspect you ask random Joe on the street they would say they would rather be on a mainframe.
Also, I would much rather my bank didn't host on AWS, GCP, Azure, etc.
- samus 5y agoThe technological state of the art at the backend is a circle. You don't have to squint that hard to see the similarities between a hypervisor running hundreds of VMs and a mainframe running hundreds of batch jobs. The difference is just that the mainframe is usually (but not always) co-located with the bank. But small bank branches might completely lack mainframe systems on their own.
- mmis1000 5y agoMainframe nowadays do support modern language and modern tech stack. It's just no one willing to move on to the next stack.(or probably too expensive to) For example, IBM z runs linux. Backward compatibility is one of the biggest selling point mainframes provide, you can run code written 30 years ago with all limitation and bug preserved as is. And IBM z can also run many program write for original ibm/360 unmodified. Probably many ones decided to do so.
