Exploring IBM SOA Technology & Practice (ISBN 978-0-9773569-2-8) is an e-book (a PDF) from Maximum Press written by Bobby Woolf (that's me). You can download a sample chapter (PDF) that contains the full table of contents and the first several pages of the e-book. It is also available as a printed paperback (ISBN 978-0-9773569-4-2) from these bookstores: Maximum Press (the publisher), Amazon, Barnes and Noble, and Borders. IBM employees can also order it from the IBM Bookstore (see my internal blog for details).
The e-book provides a concise and consistent overview of IBM SOA--the IBM approach to being successful with service-oriented architecture. While much of this material is available eslewhere--scattered around IBM's web site, conference presentations, sales materials, etc.--this e-book compiles it all together in one place in a consistent narrative that ties all of the pieces together.
The main topics in the e-book are:
Getting started with SOA – including goals, challenges, and how to select a good project
This will give you a broad overview of IBM's SOA approach in a compact format you can carry around on your disk drive. You can purchase the e-book from the publisher's web site.
