Review\\n"Modern Mainframe Development serves as a valuable overview of the platform's history and future while also thoroughly explaining its systems and processes." ―John McKenny, Senior vice president and general manager of Intelligent Z Optimization and Transformation at BMC\\n"This book is a comprehensive treatment of modern mainframe software development. It is masterfully written and thoroughly researched."—Cameron Seay, mainframe evangelist\\n"Every chapter speaks in practical terms on how to leverage the strengths of the mainframe platform."—Russ Teubner, cofounder and CEO of HostBridge Technology\\n"Tom's clearly done his homework on the current and future state of the mainframe. His conviction that hybrid cloud architectures will rule the future lays the foundation for an important and insightful breakdown of the exciting opportunities mainframe modernization presents for enterprise organizations."—Gil Peleg, CEO and founder of Model9\\n"This book is evidence that as the mainframe is modernizing, it will be critical for the next (and some of the current) generation of "mainframers" to level up faster and cover more ground. This book fast-tracks some of that ground that used to take years."—Paul Gamble, z/OS Systems Programmer—Automation, Shared Services Canada\\n"The term mainframe has had negative connotations for years. But Tom has done a great job in explaining the technology and how it is a solid option for businesses."—Lionel Dyck, z/OS enthusiast and cofounder of the Zigi open source project\\nEven as spending on digital transformation continues to skyrocket, mainframes nevertheless have major advantages for global enterprises. These systems still process huge amounts of information and allow for highly secure transactions. In this practical book, author Tom Taulli shows software developers how to pursue a hybrid approach by integrating traditional mainframes and applications with modern digital systems.\nBy the end of this book, you'll have a solid understanding of the mainframe architecture and ecosystem, including core concepts and technologies such as COBOL, REXX, JCL, Db2, VSAM, and CICS. You'll also learn how to blend in newer technologies such as the cloud, AI and machine learning, and microservices. This handbook is indispensable for enterprises looking to thrive in the new digital world. Learn strategies and approaches for mainframe DevOps Create, update, and maintain existing mainframe code, and analyze and resolve common errors Apply modern approaches to the mainframe, including microservices, APIs, cloud, and AI and machine learning Work with datasets and databases and put together effective reports Understand how to work with modern cloud systems, like AWS, for pursuing data migration
