Flow Architectures: The Future of Streaming and Event-Driven Integration

Description

Software development today is embracing events and streaming data, which optimizes not only how technology interacts but also how businesses integrate with one another to meet customer needs. This phenomenon, called flow, consists of patterns and standards that determine which activity and related data is communicated between parties over the internet. This book explores critical implications of that evolution: What happens when events and data streams help you discover new activity sources to enhance existing businesses or drive new markets? What technologies and architectural patterns can position your company for opportunities enabled by flow? James Urquhart, global field CTO at VMware, guides enterprise architects, software developers, and product managers through the process. Learn the benefits of flow dynamics when businesses, governments, and other institutions integrate via events and data streamsUnderstand the value chain for flow integration through Wardley mapping visualization and promise theory modelingWalk through basic concepts behind today's event-driven systems marketplaceLearn how today's integration patterns will influence the real-time events flow in the futureExplore why companies should architect and build software today to take advantage of flow in coming years Copyright Table of Contents Foreword Preface Conventions Used in This Book O’Reilly Online Learning How to Contact Us Acknowledgments The 10-Year Impact of the World Wide Flow The WWF in Finance The WWF in Retail The WWF in Transportation The WWF in Health Care The WWF in Data Services It Hasn’t All Been Good… The Future of the WWF Chapter 1.
