Web Services

Product Description
Like many other incipient technologies, Web services are still surrounded by a tremendous level of noise. This noise results from the always dangerous combination of wishful thinking on the part of research and industry and of a lack of clear understanding of how Web services came to be. On the one hand, multiple contradictory interpretations are created by the many attempts to realign existing technology and strategies with Web services. On the other hand, the emphasis on what could be done with Web services in the future often makes us lose track of what can be really done with Web services today and in the short term. These factors make it extremely difficult to get a coherent picture of what Web services are, what they contribute, and where they will be applied.
Alonso and his co-authors deliberately take a step back. Based on their academic and industrial experience with middleware and enterprise application integration systems, they describe the fundamental concepts behind the notion of Web services and present them as the natural evolution of conventional middleware, necessary to meet the challenges of the Web and of B2B application integration.
Rather than providing a reference guide or a “how to write your first Web service” kind of book, they discuss the main objectives of Web services, the challenges that must be faced to achieve them, and the opportunities that this novel technology provides. Established, as well as recently proposed, standards and techniques (e.g., WSDL, UDDI, SOAP, WS-Coordination, WS-Transactions, and BPEL), are then examined in the context of this discussion in order to emphasize their scope, benefits, and shortcomings. Thus, the book is ideally suited both for professionals considering the development of application integration solutions and for research and students interesting in understanding and contributing to the evolution of enterprise application technologies.
The quality of the Kindle version of this book is very poor. It looks as if one is reading a poor quality scan rather than rendered text. The type face is very light and jagged. Worse still, are the whitespace breaks between letters within words. It’s like reading code rather than prose. Unfortunately, I didn’t start reading the book until well after the seven day return policy and now I’m stuck with it but, don’t you get stuck with it. If you want this book, get the hard copy and avoid the Kindle version at all cost.

First part of the book while describing Distributed Systems, Middleware and EAI lays strong foundation for Web Services. Second part of the book provides an extensive reporting about Web Services Architecture, related standards, service composition and BPEL. Though at the outset this book looks like serving academic purpose but it also provides the great insight of the subject to the programming community.
This book is must have which draws detailed conceptual and architectural views on Distributed Systems, EAI and Web Services.
Rating: 5 / 5
A very nice introductory book on Web services, much different from all the others on this topic.
Excellent overview of the problematics of service oriented architectures on the Web and of their relationships with their EAI counterparts (corba,rpc,..).

I am using this book for a graduate level class about Web Services. I like the books approach on giving you enough background about middle-ware evolution that makes it easier to understand what Web Services are trying to accomplish. Given that the actual technology (implementation details) change so much in this area the books approach makes a lot of sense. I also found explanations to be concise and clear.
Advice: if you are looking for a hands-on how-to book about XML this is not the book to pick up. Otherwise, if you are looking for a good fundamentals book that will help you paint a big picture of Web Services this book is great!

If you want comprehensive high level overview of today’s enterprise software landscape, this is a must-read.
One of the best books which answers the question , Why Web Services?? Unique perspective on middlewares in general.
Do not expect any code examples or details of any particular middleware.
