Linux in the Cloud, on Prem, or... on a Mainframe?
summary
Modern mainframes run Linux natively and as VMs, with IBM shipping Linux One 3 and IFL chips that can reach 5.2 GHz across hundreds of processors and up to ~40 TB RAM; a DS8900F array offers 6 PB all‑flash storage. Crypto is offloaded to on‑chip engines and Crypto Express HSM cards so hardware crypto offload avoids consuming host CPU. Community ports date to Bigfoot (1998) and IBM patches (1999); there are 120-day free VMs, Travis CI support, and working Kubernetes/OpenShift integrations.
