Mainframes have been declared dead more times than JavaScript frameworks have been invented—but here they are, still running the backbone of global finance, government, and enterprise computing. And now? They’re running Kubernetes too.

This talk dives into the why and how of running Kubernetes on mainframes, from containerization on z/OS to networking, workload orchestration, and real-world use cases. We’ll break down the challenges, the benefits, and whether this is a clever hack or a genuinely viable approach for modern infrastructure. If you think mainframes are relics, think again—because they’re running microservices now.
