I generally agree with the assertion below that the value in the mainframe is the investment in intellectual property by businesses to develop their core logic that supports their business goals. The mainframe has had, and continues to support, superior technology that quite honestly has been replicated on distributed over the year (VMware and virtualization to containers and now schedulers like K8S). It has value and it has its shortcomings.
We need to focus on the continued value and not the “success” of the past. We’re on legacy version 4 by my counting. The original mainframes, then distributed technologies (lots of applications written there that are standalone), then client server and now cloud as a methodology; not a location, not a noun. The key lesson historically is we never shift everything to the next big thing, we blend them, tend them and continue the business on successive “strata” of computing evolutions. If the mainframe is chest pounding of past success it’s relevancy to the current and future technologies is diminished.
