Disclosure: I work at IBM.

Mainframes are not my area, but what I've learned makes me salivate. The next time I launch a startup, one of these Z systems is going to be on the CapEx plan.

The lowest end tier of these systems is something that could be easily afforded post series-A, and the stunning computational power is almost the least important benefit. These systems provide incredible redundancy, reliability, fault tolerance, and transaction processing speed. Decades of engineering experience have gone into building these.

You could hire engineers to figure out to make systems run reliably on a cloud provider, but unless you are one of a tiny handful of unicorns that specialize in this, you are going to do a second-rate job of it. And hiring the staff with the skill set to do that is incredibly expensive and doesn't create differentiating value.
