A funny thing happened on the way to the future (...)
summary
Mainframes still run the back end of banking and airlines, survived the COBOL staffing crisis in 2020, and now host Linux-based stacks: modern z systems pack 190 processors and up to 40 TB RAM, expose s390x cores and 85 LPARs, and LinuxONE can serve about 3,000 Linux instances. The Open Mainframe Project and community ports bring containers, Git and Hyperledger into the platform; several real migrations and a student-facing “Masked Mainframe” exercise show the tech adapts and actually works at scale.
