Have you ever stopped to wonder why you take it for granted that your credit card transactions and bank balance will be timely, reliable, and accurate, and you assume that any information the federal government has about you is not modified by hackers or processing errors? When discussing the role of the systems of record in enterprise architectures, IBM’s mainframe systems and design patterns remain an immensely important part of the overall flow of data through processing systems, and play an outsized role in providing a reliable, scalable and well-tested engine for processing information.  

Introduction to Enterprise Systems describes the design of the IBM Z hardware and operating systems, with a deep dive into how the z/OS operating system and z/OS  application software combine for maximum reliability, serviceability, and availability for processing enterprise workloads. These systems are a critical part of a reliable enterprise computing architecture to deliver an important platform that runs the world economy. This book discusses the history, context, ecosystem, and technology of the IBM Z platform and its predecessors reaching back to the original System/360 announced on April 7, 1964 and the integration capabilities and resources provided by IBM systems and software. This book provides a key reference source for understanding the critical capabilities and components of these systems and their role in a modern enterprise architecture.

Reginald Harbeck

Reg Harbeck, MA, is the first IBM Z Champion in Canada since 2020, and is a and self-described “Enthusiastic Mainframe Nerd” who has been working in IT and mainframes for over three decades. During that time, he has worked with operating systems, networks, computing security, middleware, applications and platforms ranging from Apple ][+ and MS-DOS PCs to leading edge IBM Z Mainframes. Reg has written, presented, podcasted and consulted on mainframe-related matters around the world, visiting every continent but Antarctica (so far…), and is very involved in the mainframe culture and ecosystem, including with the SHARE Board and zNextGen and SECurity projects, as well as CMG, GSE, NaSPA, and various local user groups. In 2011, Reg also co-founded Mainframe Analytics ltd., where he is the Chief Strategist.

David Boyes

David Boyes is a 35+ year practicing VM systems programmer and researcher involved with adapting creative ideas to employ existing assets to preserve and augment the value of tools and processes in a changing computing landscape.

Karl-Erik Stenfors

Karl-Erik Stenfors is a retired IBM Systems Engineer. He has spent his entire career working on the Mainframe, beginning as a System Programmer on OS/360, MFT, MVT, HASP, CICS, VM, MVS, and OS/390 with JES2.

He has worked internationally, from Lagos, Nigeria to London, UK and Montpellier, France, for organizations that include Amdahl and IBM, on assignments that range from planning a DOS/VS transformation to MVS (where he helped develop an extensive set of modifications to the environments described above – much inspired by the SHARE-tape) to the introduction of the Amdahl 5860 with MDF, to the introduction of the IBM 3090E with PR/SM which included co-writing the first of many RedBooks.

From 2000 until his retirement in 2011, he was employed by IBM, France where his major roles included execution of Early Support Programs for Mainframe hardware and operating systems in Europe, Africa, and Asia.

Since his retirement he has studied political science and been teaching Linux, Virtualization, and Assembler at three private universities in France.

Cameron Seay

Cameron Seay is an Adjunct Professor at Tennessee State University and East Carolina University.  For 8 years, he was an Assistant Professor of Information Technology in the College of Science and Technology at North Carolina Agricultural and Technical State University in Greensboro, North Carolina.   He has taught, at the college level, courses in z/OS, z/VM, REXX, and JCL.  Dr. Seay’s research focus is on “enterprise systems,” or an enterprise-centric view of computing resources. cloud computing, Big Data Analytics, and information technology andragogy.  His most recent work involves mainframe-based virtualization of Linux, open source virtual desktops, using open source big data tools (like Hadoop), and using the Raspberry Pi as a thin client.  He is a founding member of the Enterprise Computing Community (, which is the leading academic entity with a focus on enterprise systems.  He holds a doctorate in educational psychology from Georgia State University, and Master’s degrees in business, information systems, and economics.
