From the Back Cover
Complex Event Processing (CEP) is a defined set of tools and techniques for analyzing and controlling the complex series of interrelated events that drive modern distributed information systems. This emerging technology helps IS and IT professionals understand what is happening within the system, quickly identify and solve problems, and more effectively utilize events for enhanced operation, performance, and security. CEP can be applied to a broad spectrum of information system challenges, including business process automation, schedule and control processes, network monitoring and performance prediction, and intrusion detection.
The Power of Events introduces CEP and shows specifically how this innovative technology can be utilized to enhance the quality of large-scale, distributed enterprise systems. The book describes the challenges faced by today's information systems, explains fundamental CEP concepts, and highlights CEP's role within a complex and evolving contemporary context. After thoroughly introducing the concept, the book moves on to a more detailed, technical explanation of CEP, featuring the Rapide™ event pattern language, reactive event pattern rules, event pattern constraints, and event processing agents. It offers practical advice on building CEP-based solutions that solve real world IS/IT problems.
Readers will learn about such essential topics as:
- Managing the open electronic enterprise in the "global event cloud"
- Process architectures and on-the-fly process evolution
- Events, timing, causality, and aggregation
- Event patterns and event abstraction hierarchies
- Causal event tracking and information gaps
- Multiple views and hierarchical viewing
- Dynamic process architectures
- The Rapide event pattern language
- Event pattern rules, constraints, and agents
- Event processing networks (EPNs)
- Causal models and event pattern maps
- Implementing event abstraction hierarchies
Several comprehensive case studies illustrate the benefits of CEP, as well as key strategies for applying the technology. Examples include the real-time monitoring of events flowing between the business processes of collaborating enterprises, and a hierarchically organized set of event-driven views of a financial trading system. One of the case studies shows how to apply CEP to network viewing and intrusion detection.
The book concludes with a look at building an infrastructure for CEP, showing how the technology can provide a significant competitive advantage amidst the myriad of event-driven, Internet-based applications now coming onto the market.
About the Author
David Luckham is Professor Emeritus at Stanford University, where he directs the Program Analysis and Verification Project. He played a significant role in the founding of Rational Software in 1981, supplying both the Ada compiler from which the company's first products were developed and serving as a member of the initial software development team. Dr. Luckham is an acknowledged leader in high-level, multiprocessing programming languages; annotation languages; and event-based simulation systems for both hardware and software architectures. He has published more than one hundred technical articles, two of them winning ACM/IEEE Best Paper Awards, as well as three books on the design of Specification Languages and their application to software testing and verification, and hardware simulation.

The book provides no real insight and as another reviewer points out reads more like an advertisement. It's useful to read to get an overall view, but much better books exist on the subject and it seems to be catered primarily to the non-technical. The book uses a lot of buzz words, wraps the topics in "wouldn't it be nice" scenarios, etc. but provides no real meat or content.
All-in-all, decent to read, but provides no insight for business and/or technical decision making.
The first two chapters give reasons why complex event processing (CEP)is essential to the distributed systems that characterize supply chain, e-commerce and internet-enabled applications. They also sort out the key issues and present a paradigm for a global event cloud that is decomposed in subsequent chapters. Instead of providing an in-depth analysis of each chapter, which would make for a lengthly and boring review I'll give the highlights of what I liked:
- Architecture is an important theme throughout the book. In particular the Rapide architecture description language adds formality and structure. The key elements of Rapide are causal event modeling, event patterns/pattern matching and event pattern maps and constraints.
- Events, timing and causality, and their interrelationships, are thoroughly explained. These are the key to understanding the treatment of patterns, rules and constraints that follow, and for tackling the subsequent discussion of complex events and event hierarchies. This is slow reading, but the essence of the book.
- Event processing networks, which are a practical use of the knowledge imparted by this book. Moreover, the two case studies showed real world application of the concepts instead of abstract theory. They reinforced all of the key points made earlier in the book.
CEP is particularly applicable to enterprise application integration projects that depend on business events and network and systems management instrumentation (especially developers who write Tivoli software adapters, develop network monitoring solutions or similar endeavors).
