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
