SOA-Based Enterprise Integration: A Step-by-Step Guide to Services-based Application ReviewWhen I first looked at this book (after opening the package from Amazon), I thought it would be perfect... it's not a hefty 1000-page cookbook... and seemed like it would be just the perfect level of detail to rein in the broad topics into something coherent. In fact, the book does a decent job with the overall picture, but has some major flaws in style, presentation, and bias that renders it a groggy, often un-informing, experience. I stuck with it, because I had no alternative at hand, and a tight timeframe, so I can speak as a reviewer that has actually read the book.
The Good: This book contains a decent overview of SOA components and does tie them together in a good overall picture.
The Bad (part I): This book was written by an IBM Senior Architect. The technical editor for the book is an IBM Architect. The forward was written by an IBM Fellow. The back cover contains endorsements from two IBMers, one of which is the VP for WebSphere Marketing. Much of the book contains unbiased information on industry standards. However, much of the rest of the book is an over-the-top promotion of IBM products. For example, the capstone of this work is the chapter on Enterprise Service Bus. This chapter reads like glossy marketing literature for IBM products at best and like an informertial at worst. That chapter is only 30 pages long, but uses the word "WebSphere" 24 times by my count. Conversely, the non-IBM Weblogic is mentioned exactly 0 times in the same chapter, and rarely throughout the rest of the book. This book calls IBM's WESB "the prime example" of an application server based ESB and goes on to list, in bulletized form, its "features and advantages". In another section, the author states, "IBM offers the most complete product lines in this area."
The Bad (part II): This book is poorly presented. It can't decide if it is a 40,000 ft overview or a detailed description of various technologies. For example, SOAP is covered in 22 short pages. That's obviously not enough for anything more than an explanation of what it is, how it is used, why it's good, and a few examples. Yet the author tries to dive into the structure of a SOAP message to the point of who-cares detail for a book like this. In the 22 pages covering SOAP, for example, the author states FIVE TIMES that if the header element is present, it must precede the body element.
In addition, the author uses a highly verbose and repetitive style. It often seems that about 20% of the book is either telling you what it's going to tell you or telling you what it's already told you. The book could have contained the same amount of useful information in about 200 pages. This overly verbose and repetitive style gives the book a sense that the author, a PhD, does not know how to communicate effectively with lesser intellects and frequently overshoots his simplification. The result is that the work often, but inconsistently, reads a bit like a "for dummies" type of book.SOA-Based Enterprise Integration: A Step-by-Step Guide to Services-based Application Overview
Foreword by Ray Harishankar, IBM Fellow
"There are many books on the market on the topic of SOA and SOA's business and technology value.This book focuses on one of the key technical values of SOA and does an excellent job of describing SOA-based application integration by clarifying the relationship and patterns of SOA with other integration technologies in a distributed computing environment." Sandra Carter, IBM Vice President for SOA, BPM, and WebSphere Marketing
"Services Oriented Architectures present many challenges today in the integration of existing systems and new systems, along with many times, old legacy mainframe applications.This book successfully addresses many of the complexities we see in the integration of SOA and mainframe legacy applications, presenting options and approaches to integrate the applications with the rest of the enterprise.The author takes a clearly defined pattern-based approach discussing the advantages, tools and methods.Readers will benefit from the insights in this book whether they play the architect role or a developer role on a SOA project."Sue Miller-Sylvia, IBM Fellow and Application Development Service Area Leader

Service-Oriented Modeling (SOA): Service Analysis, Design, and Architecture ReviewI have purchased and read many SOA books and they have all fallen into one of 2 camps. They are usually either "HOW-TO" implement a SOAP/XML/WSDL based request response guides with the standard buzzwords of SOA Governance, WS-*Everything and the Kitchen Sink*, and of course a vague description of how an Enterprise Service Bus magically does away with years a poorly implemented legacy systems. This is the first SOA book that I have read that did not waste my time with page after page trivial XML examples but actually presented an entire working formal language(extended or inspired by the UML component model I believe) to describe your existing environment("As-Is") and future-state architecture in everday terms understandable by business users and application developers. I'll admit when I read that the approach is both 'Holistic' and 'Anthropomorphic' I felt like I was being marketed some Ginko-Biloba pseudo mysticism but as I read through I understood that this is an approach to SOA, probably the first, to actually make the the underlying services and consolidation of services visible and tanglible in the way an architect builds a scale model of a proposed structure to provide an in depth understanding of the project to those who are unable to turn equations into 3D structures in there heads(which is most of us). The authors crowning achievement, in my opinon, is the realization that everything (Legacy System, Schedule Batch Job, Business Apporval Process, Business Rules, Storage) must be treated as 'Services' is a quantum leap for SOA that moves the concept of SOA from a vague buzzword to a concrete deliverable, tangible item.Service-Oriented Modeling (SOA): Service Analysis, Design, and Architecture OverviewAnswers to your most pressing SOA development questionsHow do we start with service modeling? How do we analyze services for better reusability? Who should be involved? How do we create the best architecture model for our organization? This must-read for all enterprise leaders gives you all the answers and tools needed to develop a sound service-oriented architecture in your organization.Praise for Service-Oriented ModelingService Analysis, Design, and Architecture"Michael Bell has done it again with a book that will be remembered as a key facilitator of the global shift to Service-Oriented Architecture. . . . With this book, Michael Bell provides that foundation and more-an essential bible for the next generation of enterprise IT."-Eric Pulier, Executive Chairman, SOA Software"Michael Bell's insightful book provides common language and techniques for business and technology organizations to take advantage of the SOA paradigm. By focusing modeling techniques on the business problem, Bell provides a way for professionals to work throughout the life cycle to create reusable and enduring services."-Mike Zbranak, CIO, Chase Card Services"This book will become an imperative business and technology service-oriented modeling recipe for any manager, architect, modeler, analyst, and developer in today's software development industry."-Jeff Schneider, CEO, MomentumSI"'Innovative' and 'groundbreaking' are words that best describe Michael Bell's Service-Oriented Modeling. It depicts a true service modeling approach that elegantly closes a clear and critical service modeling gap in the SOA industry. This holistic book ties these concepts together using real-world examples across a service life cycle that transitions services from ideas and concepts into production assets that deliver business value. A must-read for business and technical SOA practitioners."-Eric A. Marks, CEO, AgilePath Corporation"As hot as SOA is today, many business and technology professionals still find it challenging to mind the gap between their disparate methodologies and objectives. Herein Michael Bell speaks clearly to both camps in straightforward language, outlining disciplines each can use to communicate effectively and advance the realization of corporate aims. This book is a bible for all who seek to drive business/technology into the future."-Mark Edward Goodrich, Director, Investing Product Management, Reuters Media"This book takes senior IT architects and systems designers into the depths of modeling for SOA, with a fresh new perspective on tools, terminology, and how to turn the theory into practice. His full life-cycle approach balances process, control, and accountability to align all the participants in the delivery pipeline-clearing the road for successful SOA business solutions."-Phil Gilligan, Chief Technology Officer, EBS
