Service-Oriented Architecture (SOA) is a software architecture where functionality is grouped around business processes and packaged as interoperable services. SOA also describes IT infrastructure which allows different applications to exchange data with one another as they participate in business processes. The aim is a loose coupling of services with operating systems, programming languages and other technologies which underlie applications. SOA separates functions into distinct units, or services, which are made accessible over a network in order that they can be combined and reused in the production of business applications. These services communicate with each other by passing data from one service to another, or by coordinating an activity between two or more services. SOA concepts are often seen as built upon, and evolving from older concepts of distributed computing and modular programming.
Fred Cummins, an EDS Fellow, presents IT as a key enabler of the agile enterprise. He demonstrates how the convergence of key technologies--including SOA, BPM and emerging enterprise and data models--can be harnessed to transform the enterprise. Cummins mines his 25 years experience to provide IT leaders, as well as enterprise architects and management consultants, with the critical information, skills, and insights they need to partner with management and redesign the enterprise for continuous change. No other book puts IT at the center of this transformation, nor integrates these technologies for this purpose.
The book first provides an overview of critical SOA and service design principles of loose coupling, interoperability, extensibility, reuse, and discoverability. Each successive chapter then offers explicit, real-world techniques for ensuring compliance with these principles. Using a focused, tutorial-based approach, the book provides working syntactical examples developed using the Altova XML Spy™ tooling and described by Web services standards such as XML, XML Schemas, WSDL and SOAP. Moreover, these examples and techniques can be used to directly implement interface design procedures, allowing you to immediately generate value from your efforts. There is simply no other volume that provides as deep, concise, and practical sets of design techniques and patterns.

This book follows up where the authors' best-selling Service-Oriented Architecture Compass left off, showing how to overcome key obstacles to successful SOA implementation and identifying best practices for all facets of execution-technical, organizational, and human. Among the issues it addresses: introducing a services discipline that supports collaboration and information process sharing; integrating services with preexisting technology assets and strategies; choosing the right roles for new tools; shifting culture, governance, and architecture; and bringing greater agility to the entire organizational lifecycle, not just isolated projects.
This book addresses IT professionals interested in the design and realization of modern security-critical applications. It presents a synthesis of various best practices, standards and technologies from model-driven software development, security engineering, and SOAs. As a reader, you will learn how to design and realize SOA security using the framework of an extensible domain architecture for model-driven security.
Service-Oriented Architecture Field Guide for Executives provides the practical guidance necessary to lay out a strategic SOA adoption plan. This practical book equips executives as well as business and technology leaders with the essential information to understand SOA, determine its relative applicability to their enterprises, and pull together a realistic plan for enterprise adoption.
This book demonstrates service-oriented architecture (SOA) as a concrete discipline rather than a hopeful collection of cloud charts. Built upon the author's firsthand experience rolling out a SOA at a major corporation, SOA in Practice explains how SOA can simplify the creation and maintenance of large-scale applications. Whether your project involves a large set of Web Services-based components, or connects legacy applications to modern business processes, this book clarifies how -- and whether -- SOA fits your needs. SOA has been a vision for years.
The key to succeeding with service-oriented architecture (SOA) is in comprehending the meaning and significance of its most fundamental building block: the service. It is through an understanding of service design that truly "service-oriented" solutions logic can be created in support of achieving the strategic goal associated with SOA and service-oriented computing. Bestselling SOA author Thomas Erl guides you through a comprehensive, insightful, and visually rich exploration of the service-orientation design paradigm, revealing exactly how services should and should not be designed for real-world SOA.
