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.

Breakthrough approach, breakthrough techniques: the first comprehensive tutorial and reference for deploying RESTful services to support SOA • •SOA and REST have been viewed as radically different paradigms: this is the first book to show how they can be combined to solve crucial problems and deliver greater business value. •Presents comprehensive case studies of the highly successful integration of contemporary REST frameworks and SOA platforms. •Covers both the theory and practice of RESTful services in the SOA context. Every major development platform now supports the creation of SOA-based solutions. Increasingly, however, the traditional, SOAP-based method of building SOA services has been challenged by a simpler, lighter alternative: REST. The two paradigms have sometimes been viewed as competitive, and many developers are comfortable with one or the other, but not both. However, REST and SOA can be used together - and, as this start-to-finish tutorial demonstrates, organizations can achieve powerful benefits by combining them. Renowned SOA expert Thomas Erl and IBM Consulting IT Architect Raj Balasubramanian begin by explaining the theory and techniques underlying REST, and then introducing real-life implementations of RESTful services using multiple contemporary technologies. The authors compare REST and service-oriented principles, showing how traditional Web services and RESTful services differ, and dispelling common myths and misconceptions about REST and SOA. Next, they present a series of REST-inspired SOA design patterns, supported by case studies that demonstrate how REST and SOA can be converged using existing technologies and products, and what the benefits are of doing so. Thomas Erl (Richmond BC) founded SOA Systems Inc., a company specializing in vendor-agnostic SOA training, certification, and strategic consulting services. Erl speaks and instructs widely, and has delivered many workshops and keynote speeches. His work has been published in publications including The Wall Street Journal. Raj Balasubramanian (Cedar Creek TX), Consulting IT Architect for IBM Software Group, works on customer engagements delivering application and infrastructure-related projects. As co author of an upcoming SOA with Java book, he contributed chapters on portal technology and REST service design and development. He recently developed REST patterns for, SOA Design Patterns.
