Modernizing the Mainframe
Mainframes are the engine of modern business growth. And from the integration of generative AI into developer workflows to the expansion of enterprise DevOps, the mainframe ecosystem has been diligently at work to ensure the long-term vitality of mainframe applications.
Here’s the latest:
In the latest episode of Big Iron Bits, we tackle mainframe misunderstandings head-on. A stressed-out Chaz fears he will fall behind if he uses the mainframe, but Broadcom’s Greg Lotko provides a mind-blowing masterclass on the economics of scale–and a convertible joyride.
AI isn't just for rewriting code; it’s a powerful tool for application analysis, debugging, and testing. With tools like GitHub Copilot and Code4z, developers are reducing code understanding time—often a three-day hurdle—to just hours.
The days of "waterfall-only" mainframe cycles are ending. Organizations are now successfully bridging modern CI/CD tools like Jenkins and Git with the mainframe using Zowe CLI and Endevor Bridge for Git. This allows developers to use modern workflows while maintaining the legendary reliability of the platform.
Breaking into the mainframe industry can seem daunting for new professionals. Nathan Thomas shares his journey of transitioning from a general programming background into a specialized mainframe career through the Broadcom Vitality Program.

It’s great to see Broadcom continuing the legacy of ADR and others. As a veteran of those systems, I can't stress enough how important it is to keep the 'Business Logic' intact while moving to the cloud. Syntax is easy for AI; original architectural intent is hard. That’s the gap we need to bridge in 2026.
