Michael Havey

This book is of great value to SOA practitioners in the semi-technical domain. It also adds value in teaching you the state of the art techniques of process integration on top of your current development processes. I am getting addicted to the SOA books of Packt Publishing.

This book picks up after high level discussions on what SOA is and is a great tool for architects and developers who have to actually build and deliver SOA. I really enjoyed reading the book and I highly recommend it!
