Stephen Foskett sits down with Steven Dickens, CEO of HyperFRAME Research, at SHARE Cleveland 2025, the world’s longest-running tech conference. Dickens shares his unique perspective bridging mainframes and open systems, discussing IBM’s new Z17 with AI acceleration, the rapid growth of LinuxONE, and the role of cloud vendors like AWS in the mainframe ecosystem. He explains how enterprises are modernizing workloads, why mission-critical industries such as banking, airlines, and payments still rely on mainframes, and how open source technologies like Kubernetes, OpenShift, and OpenTelemetry are transforming the platform. With his deep technical background from IBM and leadership in the Open Mainframe Project, Dickens shows why the mainframe remains a vital part of enterprise IT.
