But that comes at the expense of complicated software. Sure, once you've gone through the effort of procuring all that hardware, configuring it to run Kubernetes, reconfiguring your software to run in containers... you're good to go.
Mainframes allow you to easily scale your software vertically (but at the expense of complicated hardware). That might seem silly in today's world, but a lot of the software running on Z was written decades ago and the risk of rewriting it is extremely high.
