On the one hand more and more new technologies are arising, on the other hand business processes have to change because of mergers and acquisitions, new regularities, changing customer requirements and so forth. As business processes are supported by information technology, information technology has to cope with both types of changes. From a business perspective on-demand adaptation of information technology to business is required. Service-oriented architecture (SOA) is currently discussed as an opportunity to better adapt to those changes. According to Gartner's hype cycle for emerging technologies SOA already crossed the peak and is now in the trough of disillusionment. But SOA is far from being unfashionable as it would be expected during this phase. There is still high media coverage and a lot of SOA books have been published recently or will be published during the next months. What is true, however, is that the expectations are getting more realistic and people start to think about the real benefits. This is probably due to the fact that companies experienced, that implementing an SOA is not as fast and easy as the marketing hype might have given the impression. Although the hype surrounding SOA is immense, the concept is still in its early childhood with regards to concrete implementations. According to a survey conducted by Experton Group only three percent of 110 German enterprises, all with over 100 Employees, have a SOA based solution in place. Besides high costs expected from migration to SOA the lack of SOA know-how is identified as a main reason. As the survey reveals 45 percent of the interviewed enterprises have nearly no knowledge or no knowledge about SOA at all. Another 38 percent have only basic knowledge. The lack of knowledge is confirmed by a survey from the research company Quocirca, which found out, based on a sample size of 1500, that 30 percent of respondents have absolutely no knowledge about SOA and 25 percent have only minimal knowledge. Similar results are found among enterprises using SAP software. The results of an online survey conducted by the German speaking SAP User Group (DSAG) shows that 64 percent of 344 enterprises are just a little or not at all familiar with enterprise SOA and only every fifth enterprise has developed a platform strategy. Furthermore, enterprise SOA is still a topic of the IT department, although it would be [...]

Available in PDF, EPUB and Kindle. Book excerpt: "Service Oriented Architecture is a hot, but often misunderstood topic in IT today. Thomas articulately describes the concepts, specifications, and standards behind service orientation and Web Services. For enterprises adopting SOA, there is detailed advice for service-oriented analysis, planning, and design. This book is a must read!" --Alex Lynch, Principal Consultant, Microsoft Enterprise Services "One primary objective of applying SOA in design is to provide business value to the solutions we build. Understanding the right approach to analyzing, designing, and developing service-oriented solutions is critical. Thomas has done a great job of demystifying SOA in practical terms with his book." --Rick Weaver, IBM Senior Consulting Certified SW I/T Specialist "A pragmatic guide to SOA principles, strategy, and best practices that distills the hype into a general framework for approaching SOA adoption in complex enterprise environments." --Sameer Tyagi, Senior Staff Engineer, Sun Microsystems "A very timely and much needed contribution to a rapidly emerging field. Through clarifying the principles and nuances of this space, the author provides a comprehensive treatment of critical key aspects of SOA from analysis and planning to standards ranging from WS-specifications to BPEL. I''ll be recommending this book to both clients and peers who are planning on embracing SOA principles." --Ravi Palepu, Senior Field Architect, Rogue Wave Software "Finally, an SOA book based on real implementation experience in production environments. Too many SOA books get lost in the technical details of Web Services standards, or simply repeat vendor hype. This book covers the really hard parts: the complex process of planning, designing and implementing service-oriented architectures that meet organizational goals. It is an essential companion to any software developer, architect, or project manager implementing--or thinking about implementing--a service-oriented architecture." --Priscilla Walmsley, Managing Director of Datypic "Thomas Erl''s Service-Oriented Architecture: Concepts, Technology, and Design is as good an introduction to service-oriented architectures as one could wish for. In a single volume, it covers the entire topic, from theory to real-world use to technical details. The examples are superb and the writing is wonderfully clear." --Ronald Bourret, Author, "XML and Databases" "Finally an SOA book which gets to the point with real world answers and examples. Erl guides you on a real world SOA journey. From architecture design to industry standards, this book is well written and can be easily referenced for everyday use. When embarking on your own service orientated adventures, this is the book you want in your bag." --Clark Sell, Vice President, CSell Incorporated "Organizations struggling to evolve existing service-oriented solutions beyond simple Web Services now have an expert resource available. Leading the way to the true service-oriented enterprise, Thomas Erl demystifies the complexities of the open WS-I standards with detailed practical discussions and case studies. Erl''s depth and clarity makes this work a superb complement to his Field Guide." --Kevin P. Davis, PhD., Software Architect "This book is an excellent guide for architects, developers, and managers who are already working with or are considering developing Web Services or Service-Oriented Architecture solutions. The book is divided into four sections. In the first section the fundamental technologies of XML, Web Services and Service-Oriented Architectures are described in detail with attention given to emerging standards. The book is well written and very thorough in its coverage of the subject. I recommend this book highly to anyone interested in enterprise level service architectures." --Adam Hocek, President and CTO, Broadstrokes, Inc.
