Linux in the Cloud, on Prem, or on a Mainframe?

Explore the evolution and potential of Linux on mainframe systems in this 44-minute conference talk from linux.conf.au 2020. Delve into the history of time-sharing and Virtual Machine technology, tracing its roots from the 1970s mainframes to modern Linux implementations. Discover how Linux found its way onto mainframes through hobbyist efforts and IBM's subsequent development. Learn about the current landscape of Linux-exclusive mainframes, their security features including built-in encryption, and the advantages they offer over traditional x86 servers. Consider the future implications of hardware-driven encryption technologies and power-efficient alternative architectures in light of increasing data protection needs and processing demands. Gain insights into the Open Mainframe Project and tools like Zowe that are making mainframes more accessible to new developers.
