Google, Amazon, and Beyond: Creating and Consuming Web Services

From the reviews:

"In contrast to a great many other books on web services, this book is structured firmly around what is out there and what works. … A number of extended examples are used in the book … . This extended example brings together many of the topics that are covered separately. … the book also provides much useful additional, but essential, material. … Overall then, this is a useful book … . the reader can very quickly get up to speed and start experimenting."
