Understanding Enterprise SOA gives technologists and business people an invaluable and until now missing integrated picture of the issues and their interdependencies. You will learn how to think in a big way, moving confidently between technology- and business-level concerns. Written in a comfortable, mentoring style by two industry insiders, the book draws conclusions from actual experiences of real companies in diverse industries, from manufacturing to genome research. It cuts through vendor hype and shows you what it really takes to get SOA to work.
