Don’t Be Afraid of the Mainframe
The Missing Introduction for IT Leaders and Professionals
Your mainframe isn’t the problem. The uncertainty is.
Every year, CIOs and IT executives face the same impossible question: What do we do with the mainframe? Keep it? Replace it? Modernize it?
The stakes are enormous — billions in IT spend, decades of business logic, and systems that cannot fail — yet clear, vendor‑neutral guidance is almost impossible to find.
This book finally changes that.

What This Book Gives You
Don’t Be Afraid of the Mainframe cuts through the noise with 30+ years of hands‑on expertise. Whether you’re deciding the platform’s future or defending its present, this book gives you the clarity and confidence to make the right strategic decisions.
You’ll discover:
- Why the mainframe processes 70% of global transactions — and why “legacy” doesn’t mean “obsolete”
- The real economics: where costs hide, how licensing works, and what you can actually control
- Modern capabilities you didn’t know existed: AI, containers, REST APIs, DevOps, and cloud integration
- Practical frameworks for assessing your platform, applications, and transformation options
- Honest comparisons: when mainframe makes sense, when cloud is better, and how to integrate both
No sales pitch. No vendor bias. Just clear explanations, real‑world case studies, and decision frameworks you can use immediately.
