Achieving Service-Oriented Architecture: Applying an Enterprise Architecture Approach 1st Edition: “If you are considering moving to SOA or wondering whether SOA is the right direction for your company, then this book is for you. Unlike other SOA books that dive into the technical aspects of SOA, Rick takes an architectural and business approach to SOA. He describes why architecture is so important to a business and how SOA can transform your business to help reduce cost, increase efficiency, and become more profitable. In addition to describing what SOA really is, he goes the extra mile by describing in detail how to do it. Let this book serve as your guide through the relatively complex world of SOA and avoid the costly mistakes often associated with trying to figure it out on your own.”—Mark Richards, SOA and Enterprise Architect, author of Java Message Service, Second Edition

It’s a fact: no other architectural approach to business applications provides the capability to maximize efficiency and flexibility that service-oriented architecture (SOA) can offer.

Designed for CIOs, CTOs, and chief corporate architects, Achieving Service-Oriented Architecture shows you how your business can set up an SOA architecture practice, defining the policies, procedures, and standards that apply not just to IT developers, but to your entire corporation.

Defining how an enterprise architecture practice can transform itself and your corporation to maximize the benefits of the SOA approach, Achieving Service-Oriented Architecture reveals a revolutionary enterprise architecture approach and framework for implementing and managing SOA from a business organization and business practices perspective.

Presenting an architectural approach to the cultural, organizational, and operational changes that must be made across the corporate landscape to successfully achieve service-oriented architecture (SOA), Achieving Service-Oriented Architecture: Applying an Enterprise Architecture Approach strategically combines the perspectives of enterprise architecture (EA) business organization with management practice, both critical to realizing SOA’s full value.

This book reveals how you can set up your It business organizations and practices to successfully implement and run your application development life cycle under an architecturally driven SOA paradigm. Author and SOA expert Rick Sweeney shows how you can transform your EA practice so that SOA is the predominant strategic approach for applications utilized in the company.

Spelling out all the definitions and documentation needed to implement the approach, this how-to manual lets you see the entire architectural approach to SOA and what makes all the pieces of the approach fit and complement each other, explaining:

SOA has changed the entire landscape for planning, designing, implementing, and supporting business applications. While Achieving Service-Oriented Architecture is not an introduction to EA or SOA nor the technical capabilities needed to build an SOA application, this book will prepare you to challenge every aspect of your corporate culture toward an It transformation that impacts every aspect of your company.
