A Handbook for Mainframe z/OS Enterprise Architects - Architecture and Design of Large-Scale Environments

While extensive documentation exists for individual infrastructure components and architectural domains, a single, cohesive reference that comprehensively defines mainframe z/OS enterprise architecture remains largely absent. Although such works may exist, they have not come to the author's attention. This book is an effort to bridge that gap by organizing practical experience, architectural insight, and industry best practices into a unified and structured model. It reflects a synthesis of real-world expertise and disciplined thinking, aimed at providing clarity, direction, and value to enterprise architects operating in complex z/OS environments. Whether you are modernizing legacy systems, scaling mission-critical workloads, or aligning IT with evolving business demands, this handbook equips you with the clarity and confidence to make strategic architectural decisions. It is the author's sincere hope that this book serves as a trusted reference-offering both guidance and perspective to professionals involved in designing, managing, and evolving large-scale mainframe z/OS enterprise architectures.
