I’d like to express my sincere thanks to Thomas Erl for giving me the
opportunity to work on this book. It has been a privilege to be associated
with him and along the way, I have learned a lot about service-orientation.
I’d also like to thank Mark Taub at Pearson for supplying technical
books supporting my work.

To my wife, Sarah, for her tireless support.
