Welcome to Mainframe Mastery with DevOps: Integrating Legacy Systems with Agile Practices. Whether you are a seasoned mainframe professional or someone tasked with modernizing legacy systems in a rapidly evolving digital landscape, this book is designed to guide you through one of the most significant transformations happening in the world of technology: the integration of DevOps principles with mainframe operations.

Mainframes have long been the bedrock of many critical business systems, relied upon for their unmatched reliability, scalability, and processing power. But as the demand for faster development cycles, increased collaboration, and continuous delivery grows, organizations are finding that their traditional mainframe environments need to adapt. This is where DevOps—a practice that has revolutionized modern software development—comes into play. By bringing DevOps principles to mainframe environments, you can not only preserve the inherent strengths of mainframes but also unlock new efficiencies and agility.

You will explore a wide range of topics: from understanding the basics of DevOps, to automating testing and deployment, to scaling your DevOps practices and ensuring security and compliance. Whether you're tasked with breaking down operational silos, introducing continuous integration and continuous delivery, or optimizing performance across large-scale mainframe systems, this book is tailored to provide the insights, tools, and strategies you need.

The journey of modernizing mainframe systems with DevOps is not without its challenges. You may encounter resistance from teams used to traditional ways of operating, or technical hurdles in integrating new tools with legacy systems. But with the right approach, these challenges are surmountable. In fact, many organizations are already finding success by adopting DevOps practices in their mainframes—delivering faster
