Synopsis

“SOA Design Patterns is an important contribution to the literature and practice
of building and delivering quality software-intensive systems.”

- Grady Booch, IBM Fellow

“With the continued explosion of services and the increased rate of adoption of SOA through the market, there is a critical need for comprehensive, actionable guidance that provides the fastest possible time to results. Microsoft is honored to contribute to the SOA Design Patterns book, and to continue working with the community to realize the value of Real World SOA.”

- Steven Martin, Senior Director, Developer Platform Product Management, Microsoft

 

“SOA Design Patterns provides the proper guidance with the right level of abstraction to be adapted to each organization’s needs, and Oracle is pleased to have contributed to the patterns contained in this book.”

- Dr. Mohamad Afshar, Director of Product Management, Oracle Fusion Middleware, Oracle

 

“Red Hat is pleased to be involved in the SOA Design Patterns book and contribute important SOA design patterns to the community that we and our customers have used within our own SOA platforms. I am sure this will be a great resource for future SOA practitioners.”

- Pierre Fricke Director, Product Line Management, JBoss SOA Platform, Red Hat

 

“A wealth of proven, reusable SOA design patterns, clearly explained and illustrated with examples. An invaluable resource for all those involved in the design of service-oriented solutions.”

- Phil Thomas, Consulting IT Specialist, IBM Software Group

 

“This obligatory almanac of SOA design patterns will become the foundation on which many organizations will build their successful SOA solutions. It will allow organizations to build their own focused SOA design patterns catalog in an expedited fashion knowing that it contains the wealth and expertise of proven SOA best practices.”

- Stephen Bennett, Director, Technology Business Unit, Oracle Corporation

 

“The technical differences between service orientation and object orientation are subtle

enough to confuse even the most advanced developers. Thomas Erl’s book provides a great service by clearly articulating SOA design patterns and differentiating them from similar OO design patterns.”

- Anne Thomas Manes, VP & Research Director, Burton Group

 

“SOA Design Patterns does an excellent job of laying out and discussing the areas of SOA design that a competent SOA practitioner should understand and employ.”

- Robert Laird, SOA Architect, IBM

 

“As always, Thomas delivers again. In a well-structured and easy-to-understand way, this book provides a wonderful collection of patterns each addressing a typical set of SOA design problems with well articulated solutions. The plain language and hundreds of diagrams included in the book help make the complicated subjects of SOA design comprehensible even to those who are new to the SOA design world. It’s a must-have reference book for all SOA practitioners, especially for enterprise architects, solution architects, developers, managers, and business process experts.”

- Canyang Kevin Liu, Solution Architecture Manager, SAP

 

“The concept of service oriented architecture has long promised visions of agile organizations being able to swap out interfaces and applications as business needs change. SOA also promises incredible developer and IT productivity, with the idea that key services would be candidates for cross-enterprise sharing or reuse. But many organizations’ efforts to move to SOA have been mired–by organizational issues, by conflicting vendor messages, and by architectures that may amount to little more than Just a Bunch of Web Services. There’s been a lot of confusion in the SOA marketplace about exactly what SOA is, what it’s supposed to accomplish, and how an enterprise goes about in making it work.

 

SOA Design Patterns is a definitive work that offers clarity on the purpose and functioning of service oriented architecture. SOA Design Patterns not only helps the IT practitioner lay the groundwork for a well-functioning SOA effort across the enterprise, but also connects the dots between SOA and the business requirements in a very concrete way. Plus, this book is completely technology agnostic—SOA Design Patterns rightly focuses on infrastructure and architecture, and it doesn’t matter whether you’re using components of one kind or another, or Java, or .NET, or Web services, or REST-style interfaces.

 

While no two SOA implementations are alike, Thomas Erl and his team of contributors have effectively identified the similarities in composition services need to have at a sub-atomic level in order to interact with each other as we hope they will. The book identifies 85 SOA design patterns which have been developed and thoroughly vetted to ensure that a service-oriented architecture does achieve the flexibility and loose coupling promised. The book is also compelling in that it is a living document, if you will, inviting participation in an open process to identify and formulate new patterns to this growing body of knowledge.”

- Joe McKendrick, Independent Analyst, Author of ZDNet’s SOA Blog

 

“If you want to truly educate yourself on SOA, read this book.”

- Sona Srinivasan, Global Client Services & Operations, CISCO

 

“An impressive decomposition of the process and architectural elements that support serviceoriented analysis, design, and delivery. Right-sized and terminologically consistent.

 

Overall, the book represents a patient separation of concerns in respect of the process and architectural parts that underpin any serious SOA undertaking. Two things stand out. First, the pattern relationship diagrams provide rich views into the systemic relationships that structure a service-oriented architecture: these patterns are not discrete, isolated templates to be applied mechanically to the problem space; rather, they form a network of forces and constraints that guide the practitioner to consider the task at hand in the context of its inter-dependencies. Second, the pattern sequence diagrams and accompanying notes provide a useful framework for planning and executing the many activities that comprise an SOA engagement.”

- Ian Robinson, Principal Technology Consultant, ThoughtWorks

 

“Successful implementation of SOA principles requires a shift in focus from software system means, or the way capabilities are developed, to the desired end results, or real-world effects required to satisfy organizational business processes. In SOA Design Patterns, Thomas Erl provides service architects with a broad palette of reusable service patterns that describe service capabilities that can cut across many SOA applications. Service architects taking advantage of these patterns will save a great deal of time describing and assembling services to deliver the real world effects they need to meet their organization’s specific business objectives.”

- Chuck Georgo, Public Safety and National Security Architect

 

“In IT, we have increasingly come to see the value of having catalogs of good solution patterns in programming and systems design. With this book, Thomas Erl brings a comprehensive set of patterns to bear on the world of SOA. These patterns enable easily communicated, reusable, and effective solutions, allowing us to more rapidly design and build out the large, complicated and interoperable enterprise SOAs into which our IT environments are evolving.”

- Al Gough, Business Systems Solutions CTO, CACI International Inc.

 

“This book provides a comprehensive and pragmatic review of design issues in service-centric design, development, and evolution. The Web site related to this book [SOAPatterns.org] is a wonderful platform and gives the opportunity for the software community to maintain this catalogue....”

- Veronica Gacitua Decar, Dublin City University

 

“Erl’s SOA Design Patterns is for the IT decision maker determined to make smart architecture design choices, smart investments, and long term enterprise impact. For those IT professionals committed to service-orientation as a value-added design and implementation option, Patterns offers a credible, repeatable approach to engineering an adaptable business enterprise. This is a must read for all IT architect professionals.”

- Larry Gloss, VP and General Manager, Information Manufacturing, LLC

 

“These SOA patterns define, encompass, and comprise a complete repertoire of best practices for developing a world-class IT SOA portfolio for the enterprise and its organizational units through to service and schema analysis and design. After many years as an architect on many SOA projects, I strongly recommend this book be on the shelf of every analyst and technical member of any SOA effort, right next to the SOA standards and guidelines it outlines and elucidates the need for. Our SOA governance standards draw heavily from this work and others from this series.”

- Robert John Hathaway III, Enterprise Software Architect, SOA Object Systems

 

“A wise man once told me that wisdom isn’t all about knowledge and intelligence, it is just as much about asking questions. Asking questions is the true mark of wisdom and during the writing of the SOA Design Patterns book Thomas Erl has shown his real qualities. The community effort behind this book is huge meaning that Thomas has had access to the knowledge and experience of a large group of accomplished practitioners. The result speaks for itself. This book is packed with proven solutions to recurring problems, and the documented pros and cons of each solution have been verified by persons with true experience. This book could give SOA initiatives of any scale a real boost.”

- Herbjörn Wilhelmsen, Architect and Senior Consultant, Objectware

 

“This book is an absolute milestone in SOA literature. For the first time we are provided with a practical guide on how the principle centric description of service orientation from a vendor-agnostic viewpoint is actually made to work in a language based on patterns. This book makes you talk SOA! There are very few who understand SOA like Thomas Erl does, he actually put’s it all together!”

- Brian Lokhorst, Solution Architect, Dutch Tax Office

 

“Service oriented architecture is all about best practices we have learned since IT’s existence. This book takes all those best practices and bundles them into a nice pattern catalogue. [It provides] a really excellent approach as patterns are not just documented but are provided with application scenarios through case studies [which] fills the gap between theory and practice.”

- Shakti Sharma, Senior Enterprise Architect, Sysco Corp

 

“An excellent and important book on solving problems in SOA [with a] solid structure. Has the potential of being among the major influential books.”

- Peter Chang, Lawrence Technical University

 

“SOA Design Patterns presents a vast amount of knowledge about how to successfully implement SOA within an organization. The information is clear, concise, and most importantly, legitimate.”

- Peter B. Woodhull, President and Principal Architect, Modus21

 

“SOA Design Patterns offers real insights into everyday problems that one will encounter when investing in services oriented architecture. [It] provides a number of problem descriptions and offers strategies for dealing with these problems. SOA design patterns highlights more than just the technical problems and solutions. Common organizational issues that can hinder progress towards achieving SOA migration are explained along with potential approaches for dealing with these real world challenges. Once again Thomas Erl provides in-depth coverage of SOA terminology and helps the reader better understand and appreciate the complexities of migrating to an SOA environment.”

- David Michalowicz, Air and Space Operations Center Modernization Team Lead,

MITRE Corporation

 

“This is a long overdue, serious, comprehensive, and well-presented catalog of SOA design patterns. This will be required reading and reference for all our SOA engineers and architects. The best of the series so far!

 

[The book] works in two ways: as a primer in SOA design and architecture it can easily be read front-to-back to get an overview of most of the key design issues you will encounter, and as a reference catalog of design techniques that can be referred to again and again...”

- Wendell Ocasio, Architecture Consultant, DoD Military Health Systems, Agilex Technologies

 

“Thomas has once again provided the SOA practitioner with a phenomenal collection of

knowledge. This is a reference that I will come back to time and time again as I move forward in SOA design efforts.

 

What I liked most about this book is its vendor agnostic approach to SOA design patterns. This approach really presents the reader with an understanding of why or why not to implement a pattern, group patterns, or use compound patterns rather than giving them a marketing spiel on why one implementation of a pattern is better than another (for example, why one ESB is better than another). I think as SOA adoption continues to advance, the ability for architects to understand when and why to apply specific patterns will be a driving factor in the overall success and evolution of SOA. Additionally, I believe that this book provides the consumer with the understanding required to chose which vendor’s S...

Foreword

Foreword

The entire history of software engineering can be characterized as one of rising levels of abstraction. We see this in our languages, our tools, our platforms, and our methods. Indeed, abstraction is the primary way that we as humans attend to complexity—and software-intensive systems are among the most complex artifacts ever created.

I would also observe that one of the most important advances in software engineering over the past two decades has been the practice of patterns. Patterns are yet another example of this rise in abstraction: A pattern specifies a common solution to a common problem in the form of a society of components that collaborate with one another. Influenced by the writings of Christopher Alexander, Kent Beck and Ward Cunningham began to codify various design patterns from their experience with Smalltalk. Growing slowly but steadily, these concepts began to gain traction among other developers. The publication of the seminal book Design Patterns by Erich Gamma, John Vlissides, Ralph Johnson, and Richard Helm marked the introduction of these ideas to the mainstream. The subsequent activities of the Hillside Group provided a forum for this growing community, yielding a very vibrant literature and practice. Now the practice of patterns is very much mainstream: Every well-structured software-intensive system tends to be full of patterns (whether their architects name them intentionally or not).

The emerging dominant architectural style for many enterprise systems is that of a service-oriented architecture, a style that at its core is essentially a message passing architecture. However, therein are many patterns that work (and anti-patterns that should be avoided).

Thomas’ work is therefore the right book at the right time. He really groks the nature of SOA systems: There are many hard design decisions to be made, ranging from data-orientation to the problems of legacy integration and even security. Thomas offers wise counsel on each of these issues and many more, all in the language of design patterns. There are many things I like about this work. It’s comprehensive. It’s written in a very accessible pattern language. It offers patterns that play well with one another. Finally, Thomas covers not just the technical details, but also sets these patterns in the context of economic and other considerations.

SOA Design Patterns is an important contribution to the literature and practice of building and delivering quality software-intensive systems.
