Your mainframe isn’t the problem. The uncertainty is.
Whether you’re an executive making strategic decisions or an IT professional building your expertise — clear, vendor-neutral guidance on the mainframe is hard to find. Most information comes with a vendor agenda, or assumes knowledge you simply don’t have yet.
This book fills that gap.
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”, and how to modernise it
- 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.
