"By delivering SAP's next-generation applications based on a Services-Oriented Architecture, SAP is at the forefront of making Web services work for the enterprise. The Enterprise Services Architecture enables unprecedented flexibility in business process deployment, allowing companies to execute and innovate end-to-end processes across departments and companies, with minimum disruption to other systems and existing IT investments. This strategy comes to life with SAP NetWeaver, which is the technological foundation of the Enterprise Services Architecture. It provides easy integration of people, information, and systems in heterogeneous IT environments and provides a future proof application platform. Enterprise SOA provides readers with the architectural blueprints and SOA-driven project management strategies that are required to successfully adopt SOA on an enterprise level."

—Dr. Peter Graf, SVP Product Marketing, SAP

The SOA principles outlined in this book enable enterprises to leverage robust and proven middleware platforms, including CORBA, to build flexible and business-oriented service architectures. The authors also clearly describe the right strategies for using Model Driven Architecture (MDA) to manage SOA Service Repositories in a platform-independent way, enabling enterprises to better address the problem of heterogeneity at many levels. The Object Management Group was created just to address this central problem of integration in the face of constantly changing heterogeneity and platform churn, so I strongly recommend this book for the bookshelf of every enterprise architect and developer.

—Richard Mark Soley, Ph.D. chairman and chief executive officer, Object Management Group, Inc.

Enterprise SOA provides strategies that help large enterprises to increase the agility of their IT systems—one of the most pressing issues of contemporary IT. Covering both a business and architectural view, these strategies aim to promote the implementation of an IT infrastructure that can serve as a base for the development of truly flexible business processes. This book covers its subject with great profoundness based on real world evidence. It is in the interest of everybody involved with software architecture—particularly for anybody who intends to establish a Service-Oriented Architecture—to read this book.

—Dr. Helge Heß, director Business Process Management, IDS Scheer AG

"...The SOA principles described in this book are the foundation on which enterprises can build an IT architecture that will satisfy today's most important IT requirements—agility and flexibility—at affordable costs..."

—Martin Frick, Head of IT, Winterthur Group

Providing the roadmap for delivering on the promise of Service-Oriented Architecture

Enterprise SOA presents a complete roadmap for leveraging the principles of Service-Oriented Architectures to reduce cost and risk, improve efficiency and agility, and liberate your organization from the vagaries of changing technology.

• Benefit from the lessons of four enterprise-level SOA case studies from Credit Suisse, Halifax Bank of Scotland, and other world-class enterprises

• Make your business technology independent and manage infrastructure heterogeneity by focusing on architecture, not specific implementation techniques

• Recognize the technical and nontechnical success factors for SOA in the enterprise

• Define and communicate the economic value proposition of an SOA

• Apply pragmatic design principles to solve the problems of data and process integrity in an SOA environment

Whether you're a manager, architect, analyst, or developer, if you must drive greater value from IT services, Enterprise SOA will show you how—from start to finish.

No nonsense, practical advice - 2006-11-02
Reviewer Rating:
Frankly, I thought SOA was just a bunch of marketing hype until I read this book. The authors begin by clearly explaining of the kinds of problems SOA is trying to solve, and how other architectures tried and failed (or partially succeeded) to solve these problems. In fact, you don't get a definition of SOA until chapter 4, which is a good thing. The advice and strategies are well-reasoned and practical. The organizational roadmap seems to be unique among SOA books, and is clearly derived from experience. The case studies highlight the kinds of tradeoffs each organization had to deal with, along with lessons learned. Finally, I found this book to be very readable and interesting.

Honest and insightfull - 2006-05-31
Reviewer Rating:
This is a great introduction to SOA. The authors focus on the fundamentals of SOA, displaying both wisdom and honesty as they discuss the structure of an SOA, its essential and optional elements, strategies for SOA introduction (from technical and organizational points of view), SOA oriented project management techniques, success (and failure stories), etc.

The book is refreshing in the way that it avoids the vendor induced hysteria associated with new technologies choosing instead to calmly and objectively discuss the fundamental forces driving SOA adoption: federation, heterogeneity, agility, reuse.

Additionally, the authors display a healthy dose of independence as they discuss the merits and lack thereof of over-hyped technologies such as Enterprise Service Buses and BEPL systems. This is clearly a book written by people who have actually built SOAs, as opposed to sit on WS-* committees or implement SOA related junkware.

Useful at an architectural level but not at a development level - 2007-01-09
Reviewer Rating:
May be I was expecting too much out of this book, it provides good categorization of different types of services and the roadmap - however I feel it lacks some details on the technical implementation part as to what tools/technologies/standards are ideal to implement this architecture.

Again, may be my expectation was not realistic.

Excellent book with excellent examples - 2007-06-22
Reviewer Rating:
You come across very few people in life
a) who know what they are doing
b) who can teach others with good examples
c) who do not have any vested interest in sharing the knowledge.

The authors of this book come under this category. Not only they seem to have worked on many best of breed SOA projects, they have a very good ability to impart this knowledge. They discuss the pros and cons of all the options and let reader choose what is best for his/her situation.

This book seems to have the right mix of technical, management and business knowledge about SOA. Like many business oriented books it does not limit itself to discussing the organizational challenges and project management aspects. Like technical books, it does not limit itself to web services. This book opens your mind to the real IT landscape in today's organizations, particularly its heterogeneity. It opens your mind to thinking how SOA can connect these heterogeneous systems and make them productive. I have really enjoyed reading this book after completing my architect certification.

Scattered, Out-of-Date, - 2008-10-10
Reviewer Rating:
The authors attempt an ambitious goal of covering many SOA topics - but their resulting text come across as scattered - vague - and lacking a coherent and practical application.

Thomas Erl's books are much better written - and have a coherent approch to buliding a solid body of knowledge.

For a manager / salesperson wanting a broad overview of SOA - they might be better served by reading Service Oriented Architecture For Dummies
