What on earth does it do that requires a mainframe?
- nradov 1y agoIt doesn't require a mainframe but that was the cheapest path to keep things running without rewriting the software. The IBM Z platform is very good at maintaining backward compatibility. If you don't constantly keep your applications software up to date with support for new platforms then eventually you find yourself with very limited platform options.
- Aloha 1y agoThey're highly resilient - as in the hardware/OS itself is, so the applications dont have to be. That and IOPS are the primary advantage of mainframe systems.
- kelnos 1y agoNothing, but rewriting a train system from scratch and testing it is incredibly expensive and disruptive. Eventually you do have to do it, and we might not agree with their trade offs here, but it's not unreasonable.
