Dedicated to preserving and sharing mainframe knowledge for the next generation of technologists.
Mainframe Learning Hub exists to bridge the knowledge gap in mainframe technologies. As experienced mainframe professionals retire, critical knowledge and skills are at risk of being lost. We aim to preserve this knowledge and make it accessible to newcomers entering the field.
Through comprehensive tutorials, practical examples, and community resources, we help maintain the continuity of mainframe expertise that powers many of the world's most critical systems in banking, insurance, healthcare, government, and other industries.
Detailed, step-by-step guides covering mainframe technologies like JCL, COBOL, CICS, DB2, and z/OS concepts. Each tutorial is designed to build practical skills with real-world examples.
Progress tracking, exercises, and practical challenges to help reinforce concepts and build confidence in applying mainframe technologies.
Understanding the evolution of mainframe technologies helps appreciate their design decisions and continued relevance in modern computing environments.
Guidance on integrating mainframe systems with modern technologies like cloud, APIs, and DevOps practices to maintain relevance in today's digital landscape.
We are a learning platform for mainframe enthusiasts. We believe that mainframe technologies continue to offer unmatched reliability, security, and performance for mission-critical applications. By educating the next generation of mainframe professionals, we help ensure these systems continue to serve their vital role in the global technology infrastructure.
