" summary

Claim that mainframes are alive and relevant with more mainframes sold in 2018 than 1990 and Linux on s390x since 1998. Modern z15-class boxes fit standard racks, offer hardware crypto co‑processors and HSM cards exposed to Linux via dm-crypt and OpenSSL, and rackmount flash arrays with multi‑petabyte capacity. KVM/libvirt/OpenStack integration and running Kubernetes and Go workloads (encryption faster on s390x) are demonstrated; IBM offers 120‑day VMs and ongoing training like Master the Mainframe.
