Product Description
This is a comprehensive tutorial that teaches fundamental and advanced SOA design principles, supplemented with detailed case studies and technologies used to implement SOAs in the real world. ***We'll have cover endorsements from Tom Glover, who leads IBM's Web Services Standards initiatives; Dave Keogh, Program Manager for Visual Studio Enterprise Tools at Microsoft, and Sameer Tyagi, Senior Staff Engineer, Sun Microsystems. All major software manufacturers and vendors are promoting support for SOA. As a result, every major development platform now officially supports the creation of service-oriented solutions. Parts I, II, and III cover basic and advanced SOA concepts and theory that prepare you for Parts IV and V, which provide a series of step-by-step "how to" instructions for building an SOA. Part V further contains coverage of WS-* technologies and SOA platform support provided by J2EE and .NET.

This book is superb. I have read every SOA book available (up until Apr/06) because it's part of my job as a technology research analyst and all-around techno-geek. From those that I have read and studied, this is the only one I feel compelled to write a review about. AND - because I did have to go through it in such detail I'm going to raid my research notes and share with you a detailed review of not just the book, but each of its chapters.
Chapter 1 - Introduction
Nothing special here, this is just a chapter that introduces the rest of the book. Call it a glorified table of contents if you will. At first I felt like skipping it altogether, but then I did what I'm supposed to do for my job and that is read each and every part. In the end, I'm glad I took the time for two reasons: By reading a summary of each of the chapters I got a good feel for what this book was going to cover and what it wasn't going to cover. Secondly, I liked the author's intro stuff about ideal and not so ideal (real) SOA. Kind of insightful and stinging at the same time. Still, though, this is still just a description of other chapters. It's also a chapter you can get for free at the book's web site.
Chapter 2 - Case Studies
Here the author provides background information for the two companies he uses as case studies. If you're into case studies, then you'll definitely want to read through this. But - I found the subsequent samples pretty easy to follow and I think you could get away with skipping this chapter if you really wanted to.
Chapter 3 - Introducing SOA
Here's where I started getting into the meat of the book. If you think you don't understand what soa is or what the industry's made of it or turned it into then you need to read this chapter. It breaks it all down and builds it all up again in a very systematic manner. Make sure you leave this chapter with an understanding of how primitive and contemporary variations of soa are different because the author uses these terms later.
Chapter4 - The Evolution of SOA
Finally someone who makes a distinction between specification and standard and gets it right. This chapter talks about the soa industry and how vendors are responsible for soa but are also causing problems at the same time. How standards organizations are working for soa but also competing at the same time. Pretty interesting stuff and even though this was the least technical chapter, not once was I bored. It ends by comparing Ssoa with older architectures. I especially like how the author differentiates between soa and "traditional" distributed architecture that uses web services. (hint: rpc has a lot to do with it)
Chapter 5 - Web services and primitive soa
I read the author's first soa book last year and this chapter seemed to repeat a few sections from that. But if I remember correctly it goes into more detail and provides case study examples that the first book didn't have. If you're a web services veteran you can probably skip this one.
Chapter 6 -Web Services and Contemporary SOA (Part I: Activity Management and Composition)
Here he goes up a gear and dives right into that scary thing we've been calling ws-* Everything from transactions to context mgmt to orchestration and so on is covered. I really felt the author did a brilliant job building this chapter up by starting with simple meps and building up to activity management and bpel and so on. He really showed how each adds a layer over the other and how all add layers to soa.
Chapter 7 - Web Services and Contemporary SOA (Part II: Advanced Messaging, Metadata, and Security)
Yup, the rollercoast ride continues here as he gets into addressing, reliable messaging, security and other ws-* specs. All of these are specs I had already heard about and I think this type of coverage is appropriate forwhere soa is going. I forgot to mention that in this chapter and 6 he introduces 'in plain english' sections that are hilarious. They are humorous analogies that compare these complex technologies to analogies he writes about a car wash. Good, fresh writing in the usual dull and dry techno world.
Chapter 8 - Principles of Service-Orientation
Essentially a whole bunch of theory about designing services and then eight specific 'principles' (dos and don'ts) about how to design services the right way for soa. I had to go back and reread this chapter after I finished the book. I sort of glanced thru it at first but then found out that later chapters really use these principles. When I went through it again I actually thought this was pretty important stuff. This really is the next oo. You can get this chapter for free at the book web site too.
Chapter 9 - Service Layers
STudy this if you're a application architect or enterprise architect. It shows what you canh do with services built with service-orientation. The diagrams showing different types of layers combined together are pretty cool.
Chapter 10 - SOA Delivery Strategies
If you're a PM you'll love this chapter. It gets into the different phases in a soa project and how you can reorganize them using 'delivery strategies' depending on your budgets and priorities. I'd pay extra close attention to the pros and cons parts where, after documenting these strategies in abstract, the author points out their true colors.
Chapter 11 + 12 - Service-Oriented Analysis I + II
Don't know where to start when it comes to figuring out your services? Well, the author lays it all out here. He provides a process for systemtically breaking down your business logic and divying it up into services. Chapter 12 is like an instruction manual about service model. Being froma web services background this was all new to me.
Chapter 13 - 16 - Service-Oriented Design I, II, III, IV
Roll up your sleeves man, because here is where you get into the real muck of building web services for an soa. There are a bunch of processes that hash out the nitty gritty of wsdl, xsd, and bpel and show you how to build services for the types of layers set up in ch.9. Tons of code and case study samples and tips for design. This is probably the most valuable part of the book for developers and architects.
Chapter 17- Fundamental WS-* Extensions
I forgot tomention that in chapters 6 and 7 no code samples are given. He only covered ws-* specs conceptually. All of the corresponding code is placed in this chapter. A bit inconvenient if you're a developer who wants to see the code while learning about the spec, but not tragic. The neat thing is he ties the code samples into the case studies. This was my first experience with ws-* in real world tyhpe scenarios.
Chapte r18 - SOA Platforms
The author documents j2ee and .net frameworks here first in total abstract and then about how they support the different parts of soa. This was very interesting because it related a lot of the concepts stuff to actual technology and the let you compare different technologies in how they support soa.
I recommend this book to colleagures and clients and I'm recommending it here. If you have questions about SOA then this book probably has the answers you're looking for. I say that because by the time I finished reading it I ran out of questions myself.
An Important Book August 19, 2005

I have not in my long career in IT encountered anything quite as complex and confusing as what is being called service-oriented architecture or service-oriented computing. It's still distributed the way technology architectures have been for several years now. It still seems to use the same kind of technologies that internet apps have been using for the past half decade. So what exactly is a *service-oriented* system? And, more importantly, what makes it better? I looked to this book to answer these and many more questions and to address a great deal of skepticism I had regarding this whole SOA trend.
Erl's book provided me with an education in SOA and everything that surrounds it. The book systematically breaks down content into an intelligent sequence of sections and chapters that gradually and smoothly transition through basic to intermediate to advanced topics. It's a superbly written tutorial that blends coverage of technologies and theory with case studies and code examples. I honestly couldn't remember the last time I read such an organized and informative book.
I think this book will be important because SOA is becoming the next big thing (yes, I am a believer now) and because there is nothing out there even close to providing this level of insight and guidance. A classic in the making and highly recommended.
Real Insight and Value January 25, 2006

Finally got through this book (it's a biggie). I think many who give this text just a look-over will miss the importance of its depth. The important thing to realize is that this book doesn't just talk about SOA, IT ACTUALLY SHOWS YOU how to build it. This is important because you actually get real world advice and approaches for the analysis and design of services - two of the hardest parts of building SOA apps.
The first half teaches you all of the background stuff you need to know to get you to a point where you can apply thru a series of structured processes (in the second half of the book). There are already eight copies of this guide floating around my company and we have used many parts of it (although some required customization).
If you don't know or understand SOA then this book will get you up to speed. If you think you know SOA I recommend it anyway because its clarity and - most importantly - its pure definition of SOA (not clouded with vendor jargon) establishes an extremely important target model that allows you to create service-oriented apps without tie-down to any particular proprietary platform.
You often hear how this or that book is a "must read". If you are interested in SOA then this one truly is.
Great Book May 4, 2006

Very good book on SOA..
I also have to comment on one of the other reviews... by Jack Herrington. He faults the book for not covering AJAX. I would be quite surprised to see coverage of AJAX in a book on SOA. Perhaps Jack doesn't understand what SOA is? Also, he faults the book for little coverage of RSS/REST/XML-RPC. These protocols are all used in consumer web services, but SOAP is certainly the hands-down winner when it comes to Enterprise SOA. I think this book clearly has an Enterprise leaning to it, and thus its coverage of technologies is very appropriate.
Best book on Service Orientation available. August 26, 2005

Thomas Erl has done it again. This follow-up to his Field Guide is at the same time a companion volume and an extension to that work, taking the reader in new directions (service oriented analysis and design) and extensions of familiar ones (WS-* specifications).
In a service oriented enterprise, getting buy-in and beginning an analysis is critical to success. Erl uses easy-to-understand case studies to describe how to decompose business problems into manageable pieces and shows how to build the pieces up into a service-oriented backbone.
To extend the work established in the Field Guide, Erl provides practical usages of the WS-* extensions, including code snippets and examples that go beyond any previous work on the subject.
The text of this book is very easy to read, but still very detailed and techical, communicating years of practical experience in terse and accessible prose. This is a book for the true enterprise architect, but can (and should) be read and understood by anyone from technology management and software development.
