Service-Oriented Architecture: A Planning and Implementation Guide for Business and Technology

by Eric A. Marks, Michael Bell

Overview

Service-oriented architecture (SOA) is the most important—and most misunderstood—influence on information technology (IT) strategy and enterprise architecture, a critical discipline to make Web services, and services in the general sense, work together to help organizations plan, implement, and achieve SOA value. Service-Oriented Architecture: A Planning and Implementation Guide for Business and Technology clarifies and simplifies this complex topic—and complex organizational goal—unlike any other book, with extensive treatment that equips managers to proactively realize the business goals they are seeking from SOA.

Service-Oriented Architecture: A Planning and Implementation Guide for Business and Technology is applicable to all industries, technology platforms, and operating environments. It fills a need with excellent guidance from authors Eric Marks and Michael Bell, whose complementary SOA perspectives—Marks with a business and strategic perspective and Bell with a technical and architecture perspective—create a unified language of business that reconciles the semantic and linguistic barriers between the business and IT communities.

With case studies based on the authors' experiences, this logically organized and well-written field guide is packed with real-world implementation advice for newcomer or veteran business managers and IT executives, including how to:Conceptualize and understand services in an SOA context, with an SOA vision, strategy, and road mapIdentify major business challenges that SOA resolvesFocus your SOA effortsIdentify, model, and implement servicesEstablish your SOA technology and services integration modelDefine SOA governance, organization, and behavioral modelsDevelop an architecture organization modelAchieve SOA business value

Service-Oriented Architecture: A Planning and Implementation Guide for Business and Technology is the lasting SOA reference guide that IT executives, architects, team leaders, and developers will turn to for its enduring relevance and pragmatic approach to the organizational and cultural issues of SOA.

What People are Saying About This

From the Publisher

"This book provides a superb overview of the SOA topic. Marks and Bell provide practical guidance across the entire SOA life cycle—from business imperatives and motivations to the post-deployment business and technical metrics to consider. With this book, Marks and Bell demonstrate a unique ability to take the complex dynamics of SOA, and through an eloquent set of metaphors, models, and principles, provide an understandable and insightful how-to manual for both technical and business executives. This will become a required handbook for any organization implementing SOA."
—Dan Bertrand, Enterprise Technology Officer & EDS Fellow, EDS Corporation

"A fundamental breakthrough in the business and technology perspectives of SOA—this book belongs in every software developer, architect, and IT executive library. Marks and Bell demonstrate a creative and practical approach to building complex, service-oriented systems. I especially liked the hands-on perspective brought to multiple aspects of SOA. A must-have guide in the technology turbulence of the future."
—Ariel Aloni, Chief Technology Officer, SunGard Data Management Solutions

"This outstanding text gets straight to the heart of the matter, cutting through the hyperbole and discussing how to drive real business value through SOA. It will certainly impact my behavior, our governance models, and, subsequently, the successful business outcomes we derive as we continue to embrace SOA. A must-read for battle-scarred SOA veterans and fledgling architects alike."
—Christopher Crowhurst, Vice President and Chief Architect, Thomson Learning

"Too often, SOA has been perceived as 'all about the technology'—standards, technology stacks, operational monitoring, and the like. In this book, Marks and Bell expand beyond the technology to provide a refreshing business-driven perspective to SOA, connecting the dots between business requirements, architecture, and development and operations, and overlaying these perspectives with tried-and-true governance techniques to keep SOA initiatives on track. A must-read for those leading the charge to adopt SOA within their enterprise."
—Brent Carlson, Chief Technology Officer, LogicLibrary and coauthor of SanFrancisco Design Patterns: Blueprints for Business Software

"Marks and Bell have captured a wealth of practical experience and lessons learned in what has become the hottest topic in software development. In this book, they explain in detail what works and what does not, from procedural issues to technical challenges. This book is an invaluable reference for organizations seeking the benefits of SOAs."
—Dr. Jeffrey S. Poulin, System Architect, Lockheed Martin and author of Measuring Software Reuse: Principles, Practices, and Economic Models

"One of the last things companies often consider when implementing a business solution such as SOA is the impact on people. Marks and Bell provide an in-depth look at 'what has to change' from a process standpoint to make any SOA implementation a success. A great read for those considering to embark on an enterprise SOA and looking for the right mix of people, process, and products."
—Alan Himler, Vice President of Product Management and Marketing, LogicLibrary

Editorial Reviews

"In the end, SOA, delivers what is the first and perhaps most comprehensive road map yet for IT executives, team leaders and developers, whether they are in the business field or government." (Public CIO, October 2006)
