As XML becomes an increasingly significant part of the IT mainstream, expert guidance and common-sense strategies are required to avoid the many pitfalls of applying XML incorrectly or allowing it to be used in an uncontrolled manner. This book acts as a knowledge base for issues relating to integration, and provides clear, concise advice on how to best determine the manner and direction XML technology should be positioned and integrated. The book will be one of the first to provide documentation for second-generation Web services technologies (also known as WS-*). The importance of these specifications (which include BPEL, WS-Transaction, WS-Coordination, WS-Security, WS-Policy, and WS-Reliable Messaging) cannot be understated. Major standards organizations and vendors are supporting and developing these standards. ***David Keogh, Program Manager for Enterprise Frameworks and Tools, Microsoft, will provide a front cover quotation for the book.

SOA with REST
by Thomas Erl, Benjamin Carlyle, Cesare Pautasso, and Raj Balasubramanian
The Definitive Guide to Building Web-Centric SOA with REST
The World Wide Web is based on the most successful technology architecture in history. It has changed how we view, access, and exchange information and, with the advent of REST, it has also provided us with compelling ways to build and improve automation solutions. REST provides a great deal of guidance to ensure that an architecture and its automation logic are technically sound, though it is still your responsibility to build services that actually add value to your business.
SOA with REST is the first comprehensive tutorial and reference for designing and building RESTful services as part of service-oriented solutions and in conjunction with service-oriented architecture (SOA). This book demonstrates that REST is not only a suitable medium for building truly service-oriented solutions, but also that the service-oriented architectural model is a necessary foundation for REST technology architectures to realize their full business potential.
The authors provide thorough mapping of REST constraints and architectural goals with service-orientation principles and SOA characteristics. Using real-world examples, they show how to leverage REST’s simplicity, flexibility, and low overhead without compromising the power or manageability of service-oriented solutions and architectures.
This ebook will be valuable to IT architects, developers, and any practitioner seeking to use SOA and REST together.

Web Service Contract Design and Versioning for SOA
by Thomas Erl, Anish Karmarkar, Priscilla Walmsley, Hugo Haas, L Umit Yalcinalp, Kevin Liu, David Orchard, Andre Tost, and James Pasley
The Ultimate Guide for Designing and Governing Web Service Contracts
For Web services to succeed as part of SOA, they require balanced, effective technical contracts that enable services to be evolved and repeatedly reused for years to come. Now, a team of industry experts presents the first end-to-end guide to designing and governing Web service contracts. Writing for developers, architects, governance specialists, and other IT professionals, the authors cover the following areas:
Understanding Web Service Contract Technologies
Initial chapters and ongoing supplementary content help even the most inexperienced professional get up to speed on how all of the different technologies and design considerations relate to the creation of Web service contracts. For example, a visual anatomy of a Web service contract documented from logical and physical perspectives is provided, along with a chapter dedicated to describing namespaces in plain English. The book is further equipped with numerous case study examples and many illustrations.
Fundamental and Advanced WSDL
Tutorial coverage of WSDL 1.1 and 2.0 and detailed descriptions of their differences is followed by numerous advanced WSDL topics and design techniques, including extreme loose coupling, modularization options, use of extensibility elements, asynchrony, message dispatch, service instance identification, non-SOAP HTTP binding, and WS-BPEL extensions. Also explained is how WSDL definitions are shaped by key SOA design patterns.
Fundamental and Advanced XML Schema
XML Schema basics are covered within the context of Web services and SOA, after which advanced XML Schema chapters delve into a variety of specialized message design considerations and techniques, including the use of wildcards, reusability of schemas and schema fragments, type inheritance and composition, CRUD-style message design, and combining industry and custom schemas.
Fundamental and Advanced WS-Policy
Topics, such as Policy Expression Structure, Composite Policies, Operator Composition Rules, and Policy Attachment establish a foundation upon which more advanced topics, such as policy reusability and centralization, nested, parameterized, and ignorable assertions are covered, along with an exploration of creating concurrent policy-enabled contracts and designing custom policy assertions and vocabularies.
Fundamental Message Design with SOAP
A broad range of message design-related topics are covered, including SOAP message structures, SOAP nodes and roles, SOAP faults, designing custom SOAP headers and working with industry-standard SOAP headers.
Advanced Message Design with WS-Addressing
The art of message design is taken to a new level with in-depth descriptions of WS-Addressing endpoint references (EPRs) and MAP headers and an exploration of how they are applied via SOA design patterns. Also covered are WSDL binding considerations, related MEP rules, WS-Addressing policy assertions, and detailed coverage of how WS-Addressing relates to SOAP Action values.
Advanced Message Design with MTOM, and SwA
Developing SOAP messages capable of transporting large documents or binary content is explored with a documentation of the MTOM packaging and serialization framework (including MTOM-related policy assertions), together with the SOAP with Attachments (SwA) standard and the related WS-I Attachments Profile.
Versioning Techniques and Strategies
Fundamental versioning theory starts off a series of chapters that dive into a variety of versioning techniques based on proven SOA design patterns including backward and forward compatibility, version identification strategies, service termination, policy versioning, validation by projection, concurrency control, partial understanding, and versioning with and without wildcards.
Web Service Contracts and SOA
The constant focus of this book is on the design and versioning of Web service contracts in support of SOA and service-orientation. Relevant SOA design principles and design patterns are periodically discussed to demonstrate how specific Web service technologies can be applied and further optimized. Furthermore, several of the advanced chapters provide expert techniques for designing Web service contracts while taking SOA governance considerations into account.

SOA with REST
by Thomas Erl, Benjamin Carlyle, Cesare Pautasso, and Raj Balasubramanian
“This book illuminates the connection of the two domains--SOA and REST--in a manner that is concrete and practical, providing concise application to everyday architectural challenges. Fantastic!”
--Ryan Frazier, Technology Strategist, Microsoft
“...a tour de force that elegantly applies REST principles to the industry-standard SOA framework described in prior titles in this series.... This book is a must-read for anyone developing REST services.”
--Dave Slotnick, Enterprise Architect, Rackspace Hosting
“This book undoubtedly will help SOA to reap the benefits from the main value propositions of Web architecture....”
--Dr. Erik Wilde, Architect, EMC Corporation
“REST is so much more than just another type of interface implementation--SOA with REST shows how the ecosystem of service compositions changes as new opportunities arise for service composition architecture designs. A comprehensive guide and a must-read for any serious IT architect considering REST-style services for application architectures.”
--Roger Stoffers, Solution Architect, Hewlett Packard
“Service-orientation and REST both are architectural styles that are cornerstones of modern applications and cloud computing. Both aim to deliver scalable, interoperable solutions, but their different roots don’t always make them a natural fit. SOA with REST explains how the two styles can work together in enterprise environments. It discusses a design process for a services portfolio that meets the goals of SOA and at the same time designs services that comply with the established REST constraints. It also shows pragmatic approaches to meet enterprise-grade requirements with the REST programming style but relaxes constraints where necessary.”
--Christoph Schittko, Director of Cloud Strategy, Microsoft
“An excellent repertoire of service-oriented patterns that will prove handy when solving problems in the real world. The REST perspectives and principles will provide complete coverage of modern-day Web 2.0 style approaches. Highly recommended.”
--Sid Sanyal, IT Architect, Zurich Financial Services
“An inspirational book that provides deep insight into the design and development of next-generation service-oriented systems based on the use of REST. This book clarifies the convergence of SOA and REST with no-nonsense content that addresses common questions and issues head-on.

“REST and SOA are two of the most misunderstood terms in the software industry over the past decade. Yet the REST architectural style coupled with modern RESTful framework implementations provides a scalable and reliable approach to SOA. This book covers all you need to know about how to take the principles of REST and apply them in small and large SOA developments. If you are familiar with REST and thinking about SOA, then you need this book. If you have not considered REST in your SOA work, then this book is for you, too. Covering concepts of both REST and SOA, as well as design patterns and when to use them, the book is a wonderful companion and a good tool for architects and engineers.”
--Dr. Mark Little, CTO JBoss, Red Hat
“Unlike many other texts on the subject, SOA with REST is a well-rounded, easy-to-read narrative, including real-world case studies that appeal to both developers and analysts. This makes it an indispensable source for any SOA practitioner or any professional who is planning to initiate an SOA project.”
--Theodore T. Morrison, Certified SOA Analyst, CSM, Geocent, LLC
“SOA and REST are two very important architectural styles for distributed computing. SOA is successfully adopted by most enterprises, and the REST style is getting more attention from both researcher and industry users. The book SOA with REST introduces a new architectural style that is ingeniously combining both SOA and REST styles and clearly reveals how SOA and REST can work together to generate successful enterprise SOA strategies with REST, along with guidance for making architecture design decisions. This book is a bible of best practices for designing and implementing SOA architecture with REST. It is a must-have reference book for both IT practitioners and researchers.”

The Definitive Guide to Building Web-Centric SOA with REST
The World Wide Web is based on the most successful technology architecture in history. It has changed how we view, access, and exchange information and, with the advent of REST, it has also provided us with compelling ways to build and improve automation solutions. REST provides a great deal of guidance to ensure that an architecture and its automation logic are technically sound, though it is still your responsibility to build services that actually add value to your business.
SOA with REST is the first comprehensive tutorial and reference for designing and building RESTful services as part of service-oriented solutions and in conjunction with service-oriented architecture (SOA). This book demonstrates that REST is not only a suitable medium for building truly service-oriented solutions, but also that the service-oriented architectural model is a necessary foundation for REST technology architectures to realize their full business potential.
The authors provide thorough mapping of REST constraints and architectural goals with service-orientation principles and SOA characteristics. Using real-world examples, they show how to leverage REST’s simplicity, flexibility, and low overhead without compromising the power or manageability of service-oriented solutions and architectures.
This book will be valuable to IT architects, developers, and any practitioner seeking to use SOA and REST together.

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.

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

[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 SOA products are right for their specific needs.”
- Bryan Brew, SOA Consultant, Booz Allen Hamilton
“A must have for every SOA practitioner.”
- Richard Van Schelven, Principal Engineer, Ericsson
“This book is a long-expected successor to the books on object-oriented design patterns and integration patterns. It is a great reference book that clearly and thoroughly describes design patterns for SOA. A great read for architects who are facing the challenge of transforming their enterprise into a service-oriented enterprise.”
- Linda Terlouw, Solution Architect, Ordina
“The maturation of Service-Orientation has given the industry time to absorb the best practices of service development. Thomas Erl has amassed this collective wisdom in SOA Design Patterns, an absolutely indispensible addition to any Service Oriented bookshelf.”
- Kevin P. Davis, Ph.D
“The problem with most texts on SOA is one of specificity. Architects responsible for SOA implementation in most organizations have little time for abstract theories on the subject, but are hungry for concrete details that they can relate to the real problems they face in their environment. SOA Design Patterns is critical reading for anyone with service design responsibilities. Not only does the text provide the normal pattern templates, but each pattern is applied in detail against a background case study to provide exceptionally meaningful context to the information. The graphic visualizations of the problems and pattern solutions are excellent supplementary companions to the explanatory text. This book will greatly stretch the knowledge of the reader as much for raising and addressing issues that may have never occurred to the reader as it does in treating those problems that are in more common occurrence. The real beauty of this book is in its plain English prose. Unlike so many technical reference books, one does not find themselves re-reading sections multiple times trying to discern the intent of the author. This is also not a reference that will sit gathering dust on a shelf after one or two perusings. Practitioners will find themselves returning over and over to utilize the knowledge in their projects. This is as close as you’ll come to having a service design expert sitting over your shoulder.”
- James Kinneavy, Principal Software Architect, University of California
“As the industry converges on SOA patterns, Erl provides an outstanding reference guide to composition and integration–and yet another distinctive contribution to the SOA practice.”
- Steve Birkel, Chief IT Technical Architect, Intel Corp.
“With SOA Design Patterns, Thomas Erl adds an indispensable SOA reference volume to the technologist’s library. Replete with to-the-point examples, it will be a helpful aid to any IT organization.”
- Ed Dodds, Strategist, Systems Architect, Conmergence
“Again, Thomas Erl has written an indispensable guide to SOA. Building on his prior successes, his patterns go into even more detail. Therefore, this book is not only helpful to the SOA beginner, but also provides new insight and ideas to professionals.”
- Philipp Offermann, Research Scientist, Technische Universität Berlin, Germany
“SOA Design Patterns is an extraordinary contribution to SOA best practices! Once again, Thomas has created an indispensable resource for any person or organization interested in or actively engaged in the practice of Service Oriented Architecture. Using case studies based on three very different business models, Thomas guides the reader through the process of selecting appropriate implementation patterns to ensure a flexible, well-performing, and secure SOA ecosystem.”
- Victor Brown, Managing Partner and Principal Consultant,
Cypress Management Group Corporation
