"Paul Brown has done a favor for the TIBCO community and anyone wanting to get into this product set. Architecting TIBCO solutions without knowing the TIBCO architecture fundamentals and having insight to the topics discussed in this book is risky to any organization. I fully recommend this book to anyone involved in designing solutions using the TIBCO ActiveMatrix products." -Nikky Sooriakumar, TIBCO Architect, PruHealth "An effective primer for building composite services using TIBCO, this book provides a holistic approach to strategy integrated with implementation details. I find it tremendously useful in moving recursively from business solutions to design patterns to architecture. Tangible examples are provided that build to composite services. And advanced topics are explored that add another valuable implementation dimension. I recommend this book to software architects who need to quickly build an effective business- services-oriented environment." -Abby H. Brown, Ph.D., Enterprise Architect, Intel Corp. The architecture series from TIBCO (R) Press comprises a coordinated set of titles for software architects and developers, showing how to combine TIBCO components to design and build real-world solutions. TIBCO's product suite comprises components with functionality ranging from messaging through services, service orchestration, business process management, master data management, and complex event processing. In composite applications and services, multiple components collaborate to provide the required functionality. There are many possible architectures for these distributed solutions: Some will serve the enterprise well, while others will lead to dead-end projects. Architecting Composite Applications and Services with TIBCO (R) shows how to create successful architectures with TIBCO products for both overall solutions and individual services. This guide builds on the basic design patterns and product information presented in the first title in the series, TIBCO (R) Architecture Fundamentals (Addison-Wesley, 2011). After reading this title, you will be able to Create architectures for solutions, service specifications, and service implementations Understand the intended TIBCO product roles in composite applications and services Define manageable approaches to service versioning and naming Conduct and interpret performance benchmarks Identify and select appropriate design patterns for a variety of tasks Architecting Composite Applications and Services with TIBCO (R) is intended primarily for project architects defining overall solutions and specifying the supporting components and services. TIBCO developers, enterprise architects, and technical managers will also find material of interest. No specific prior knowledge of architecture is assumed.
Dr. Paul C. Brown, a Principal Software Architect at TIBCO Software Inc., is the author of Succeeding with SOA (Addison-Wesley, 2007), Implementing SOA (Addison-Wesley, 2008), and TIBCO (R) Architecture Fundamentals (Addison-Wesley, 2011), and is a coauthor of the SOA Manifesto (soa-manifesto.org). Dr. Brown's extensive design work on enterprise-scale information systems led him to develop the concept of total architecture, which explains how business processes and information systems are so intertwined that they must be architected together.
