Event-Driven Architecture: How SOA Enables the Real-Time Enterprise

Improving Business Agility with EDA   Going beyond SOA, enterprises can gain even greater agility by implementing event-driven architectures (EDAs) that automatically detect and react to significant business events. However, EDA planning and deployment is complex, and even experienced SOA architects and developers need expert guidance. In Event-Driven Architecture, four leading IT innovators present both the theory of EDA and practical, step-by-step guidance to implementing it successfully.   The authors first establish a thorough and workable definition of EDA and explore how EDA can help solve many of today’s most difficult business and IT challenges. You’ll learn how EDAs work, what they can do today, and what they might be able to do as they mature. You’ll learn how to determine whether an EDA approach makes sense in your environment and how to overcome the difficult interoperability and integration issues associated with successful deployment. Finally, the authors present chapter-length case studies demonstrating how both full and partial EDA implementations can deliver exceptional business value. Coverage includes   How SOA and Web services can power event-driven architectures The role of SOA infrastructure, governance, and security in EDA environments EDA core components: event consumers and producers, message backbones, Web service transport, and more EDA patterns, including simple event processing, event stream processing, and complex event processing Designing flexible stateless events that can respond to unpredictable customers, suppliers, and business partners Addressing technical and business challenges such as project management and communication EDA at work: real-world applications across multiple verticals   Hugh Taylor is a social software evangelist for IBM Lotus Software. He coauthored Understanding Enterprise SOA and has written extensively on Web services and SOA. He holds an MBA from Harvard Business School. Angela Yochem is an executive in a multinational technology company and is a recognized thought leader in architecture and large-scale technology management. Les Phillips, VP, enterprise architecture, at SunTrust Banks Inc., is responsible for defining the strategic and business IT foundation for many areas of the enterprise. Frank Martinez, EVP, product strategy, at SOA Software, is a recognized expert on distributed, enterprise application, and infrastructure platforms. He has served as senior operating executive for several venture-backed firms and helped build Intershop Communications into a multibillion-dollar public company.   Foreword     xi Preface     xii Introduction      1 Event-Driven Architecture: A Working Definition     1 The “New” Era of Interoperability Dawns     6 The ETA for Your EDA     9 Endnotes     9   PART I THE THEORY OF EDA Chapter 1 EDA: Opportunities and Obstacles     13 The Vortex     13 EDA: A Working Systemic Definition     14 The (Not So Smooth) Path to EDA     24 Defining Interoperability     26 Drivers of Interoperability     28 Application Integration: A Means to Interoperate     29 Interoperation and Business Process Management     31 Is There a Diet for All This Spaghetti?      35 How Architecture Promotes Integration     37 Management and Governance     39 Chapter Summary     43 Endnote     45   Chapter 2 SOA: The Building Blocks of EDA     47 Making You an Offer You Can’t Understand     47 SOA: The Big Picture     48 Defining Service     49 Service-Based Integration     50 Web Services     51 What Is SOA?      59 Loose Coupling in the SOA     60 Chapter Summary     61   Chapter 3 Characteristics of EDA     63 Firing Up the Corporate Neurons     63 Revisiting the Enterprise Nervous System     63 The Ideal EDA     78 BAM--A Related Concept     86 Chapter Summary     87 Endnotes     89   Chapter 4 The Potential of EDA     91 Introduction     91 EDA’s Potential in Enterprise Computing     91 EDA and Enterprise Agility     100 EDA and Society’s Computing Needs     102 EDA and Compliance     107 Chapter Summary     108   Chapter 5 The SOA-EDA Connection     111 Getting Real     111 Event Services     112 The Service Network     114 Implementing the SOA and Service Network     116 How to Design an SOA     122 The Real “Bottom Line”      134 Chapter Summary     137   PART II EDA IN PRACTICE Chapter 6 Thinking EDA     141 A Novel Mind-Set     141 Reducing Central Control     142 Thinking about EDA Implementation     148 When EDA Is Not the Answer     151 An EDA Product Examined     153 Chapter Summary     157 Endnotes     158   Chapter 7 Case Study: Airline Flight Control     159 Learning Objectives     160 Business Context: Airline Crunch Time     160 The Ideal Airline Flight Control EDA     167 What FEDA Might Look Like in Real Life     176 Program Success     197 Chapter Summary     206 Endnotes     207   Chapter 8 Case Study: Anti-Money Laundering     209 Learning Objectives     210 Cracking a Trillion Dollar, Global Crime Wave     210 IT Aspects of Anti-Money Laundering     216 EDA as a Weapon in the War on Money Laundering     221 Chapter Summary     259 Endnotes     260   Chapter 9 Case Study: Event-Driven Productivity Infrastructure     261 Learning Objectives     262 The Often Inadequate Human Link in the EDA     262 Overview of Productivity Infrastructure     264 The Potential Benefits of EDA-PI Integration     267 ProdCo, an EDA-PI Integration Scenario     273 Chapter Summary     293 Endnotes     294
