3. CICS, and COBOL, and Copybooks; Oh My!

In this illuminating presentation, veteran systems architect Boyd Hays takes viewers inside a real-world CICS modernization project from the mid-1990s to reveal timeless principles for integrating heritage systems with modern platforms. Drawing on decades of mainframe and distributed systems experience, Hays demonstrates how metadata-driven architectures enable seamless interoperability without sacrificing the proven reliability of mission-critical systems.

Through a detailed case study of a 3-week proof-of-concept that bridged CICS transactions with Smalltalk workstations, Hays explores the fundamental architecture of IBM's dominant transaction processing platform and shows how its design principles remain relevant for today's modernization challenges. Rather than treating legacy systems as obstacles to progress, this presentation reveals how understanding their underlying strengths can inform smarter platform decisions.

Key Topics:

• Deep dive into CICS, COBOL, and Copybook architecture
• Metadata-driven integration patterns that preserve system semantics
• Why heritage systems survive and what that teaches us
• Platform selection based on workload physics, not technology trends
• The hidden costs of distributed architectures
• Practical approaches to hybrid modernization
• Real implementation details from working code

Part three of the "Road to Modernization" series - essential viewing for organizations seeking to modernize thoughtfully rather than simply migrate to the latest platform.

Perfect for: Mainframe modernization teams, enterprise architects, CTOs evaluating platform strategies, and engineering leaders responsible for systems where "there's no such thing as a free distributed systems lunch."
