SOA Principles of Service Design ReviewWhere do I start?On the positive side. It is the only computer book I have read in years that is completely free of typing and grammatical errors.
On the negative:
Thomas Erls' previous book contains lots of valuable information about services. This book does not.
A good design book would have contained more.
Every time he starts to discuss something of depth, it is always beyond the scope of the book, contained in the companion Design Patterns book or in a book that he has yet to write, or he references another chapter containing a paragraph of clarification. The OOAD section is great, but that's not the topic of the book.
You know those articles where the text is great, but the diagrams confusing and innane. Well in this book, the diagrams are inane and so is their description. Take for example, page 327. There is a drawing of a stationary car and a moving car. The text reads "State refers to the general condition of something. A car that is moving is in a state of motion, whereas a car that is not moving is in a stationary state." What enlightenment. Another figure, Figure 8.10 ( I know it well ), is repeated 4 times on two pages, and at various other places, with only changes to the text. I can't help but feeling, that if I read all of the following books that this one promotes, I may get one book's worth of content.
I know that my review differs from the others. I have extensive experience in design ( although not SOA design ), and found most of what was discussed repetetive and obvious. Also I can't help but notice when I look at other reviewers' profiles, they have only ever reviewed one book, or at most two.
I will probably buy, or at least checkout the SOA patterns book ( referenced extensively in this one as published, but lost in book desert ). I hope it contains the content that this book should have contained.
SOA Principles of Service Design Overview"This book could be described as an encyclopedia of service design–Erl leaves nothing to chance. Indispensable."–Steve Birkel, Chief IT Technical Architect, Intel Corp."An absolute pleasure to read…the best SOA book I've read.A book I would recommend to all of my colleagues; it provides much insight to the topics often overlooked by most books in this genre…the visuals were fantastic."–Brandon Bohling, SOA Architecture and Strategy, Intel Corporation"This book is a milestone in SOA literature. For the first time we are provided with a practical guide on defining service characteristics and service design principles for SOA from a vendor-agnostic viewpoint. It's a great reference for SOA discovery, adoptions, and implementation projects."–Canyang Kevin Liu, Principal Enterprise Architect, SAP Americas, Inc."I liked this book. It contains extremely important material for those who need to design services."–Farzin Yashar, IBM SOA Advanced Technologies"This book does a great job laying out benefits, key ideas and design principles behind successfully adopting service-oriented computing. At the same time, the book openly addresses challenges, risks and trade-offs that are in the way of adopting SOA in the real-world today. It moves away from ivory-tower views of service orientation, but still lays out a strong vision for SOA and outlines the changes necessary to realize the full potential."–Christoph Schittko, Senior Architect, Microsoft"I recommend this book to any SOA practitioner who wishes to empower themselves in making service design real…gives readers the 360º view into service design [and] gives SOA practitioners the depth and understanding needed into the principles of SOA to assist in the design of a mature and successful SOA program."–Stephen G. Bennett, Americas SOA Practice Lead, BEA Systems"SOA projects are most successful when they are based on a solid technical foundation. Well accepted and established design principles are part of this foundation. This book takes a very structured approach at defining the core design principles for SOA, thus allowing the reader to immediately applying them to a project. Each principle is formally introduced and explained, and examples are given for how to apply it to a real design problem. A 'must read' for any architect, designer or developer of service oriented solutions".–Andre Tost, Senior Technical Staff Member, IBM Software Group"There are few references for SOA that give you the nuts and bolts and this one is at the top of the list. Well written and valuable as a reference book to any SOA practitioner."–Dr. Mohamad Afshar, Director of Product Management, Oracle Fusion Middleware, Oracle Corporation"A thorough examination of the considerations of service design. Both seasoned SOA practitioners and those endeavoring to realize services can benefit from reading this book."–Bill Draven, Enterprise Architect, Intel Corporation"There are very few who understand SOA like Thomas Erl does! The principle centric description of service orientation from Thomas canonizes the underpinnings of this important paradigm shift in creating agile and reusable software capabilities. The principles, so eloquently explained, leave little room for any ambiguity attached to the greater purpose of SOA. Most organizations today are creating services in a bottoms-up approach, realizing composition and reuse organically. The time is ripe for a book like this that prepares architects for a principle centric approach to SOA."–Hanu Kommalapati, Architect, Microsoft Corporation"Outstanding SOA literature uniquely focused on the fundamental services design with thorough and in-depth study on all practical aspects from design principles to methodologies. This book provides a systematic approach for SOA adoption essential for both IT management and professionals."–Robin Chen, PhD, Google, Inc."Thomas Erl's books are always densely filled with information that's well structured. This book is especially insightful for Enterprise Architects because it provide s great context and practical examples. Part 1 of the book alone is worth getting the book for."–Markus Zirn, Senior Director, Product Management, Oracle Fusion Middleware, Oracle Corporation"A very clear discussion of the subject matter. Provides a good structure that facilitates understanding and readily highlights key points."–Kareem Yusuf, Director of SOA Strategy and Planning, IBM Software Group"I am very impressed. Comprehensive. Educative. This book helped me to step back and look at the SOA principles from broader perspective. I'd say this is a must-read book for SOA stakeholders."–Radovan Janecek, Director R&D, SOA Center, Hewlett-Packard"Very valuable guidance for understanding and applying SOA service design principles with concrete examples. A must read for the practitioner of SOA service design."–Umit Yalcinalp, PhD, Standards Architect, SAP"This book really does an excellent job of explaining the principles underpinning the value of SOA…Erl goes to great length to explain and give examples of each of the 8 principles that will significantly increase the readers ability to drive an SOA service design that benefits both business and IT."–Robert Laird, IT Architect, IBM EAI/SOA Advanced Technologies Group"This book strikes a healthy balance between theory and practice. It is a perfect complement to the SOA series by the author."–Prakash Narayan, Sun Microsystems"If you are going to be designing, developing, or implementing SOA, this is a must have book."–Jason "AJ" Comfort Sr., Booz Allen Hamilton"An excellent book for anyone who wants to understand service-orientation and the principles involved in designing services…a clear, concise and articulate exploration of the eight design principles involved in analyzing, designing, implementing, and maintaining services…"–Anish Karmarkar, Oracle Corporation"Very well written, succinct, and easy to understand."–Raj Balasubramanian, IBM Software Group"Acomprehensive exploration of the issues of service design which has the potential to become the definitive work in this area."–James Pasley, Chief Technology Officer, Cape Clear Software"An excellent addition to any SOA library; it covers a wide range of issues in enough detail to be a valuable asset to anyone considering designing or using SOA based technologies."–Mark Little, Director of Standards, Red Hat"This book communicates complex concepts in a clear and concise manner. Examples and illustrations are used very effectively."–Darryl Hogan, Senior Architect, Microsoft"A work of genius…Offers the most comprehensive and thorough explanation on the principles of service design and what it means to be 'service oriented.'"Erl's treatment of the complex world of service oriented architecture is pragmatic, inclusive of real world situations and offers readers ways to communicate these ideas through illustrations and well formulated processes."–David Michalowicz, MITRE Corporation"This is the book for the large organization trying to rationalize its IT assets and establish an agile platform for the future.
