Information Technology professionals can use this book to move beyond the excitement of web services and service oriented architecture (SOA) and begin the process of finding actionable ideas to innovate and create business value. In Enterprise SOA: Designing IT for Business Innovation, SAP's blueprint for putting SOA to work is analyzed from top to bottom. In addition to design, development, and architecture, vital contextual issues such as governance, security, change management, and culture are also explored. This comprehensive perspective reduces risk as IT departments implement ESA, a sound, flexible architecture for adapting business processes in response to changing market conditions.

This book answers the following questions:

• What forces created the need for Enterprise Services Architecture?

• How does ESA enable business process innovation?

• How is model-driven development used at all levels of design, configuration, and deployment?

• How do all the layers of technology that support ESA work together?

• How will composite applications extend business process automation?

• How does ESA create new models for IT governance?

• How can companies manage disruptive change?

• How can enterprise services be discovered and designed?

• How will the process of adapting applications be simplified?

Based on extensive research with experts from the German software company SAP, this definitive book is ideal for architects, developers, and other IT professionals who want to understand the technology and business relevance of ESA in a detailed way--especially those who want to move on the technology now, rather than in the next year or two.

Very Helpful Book on SOA - 2006-07-11
Reviewer Rating:
This is a very helpful book on SOA because it provides the business case for SOA, an excellent technical overview, and real-life examples of how to use it.

While it is written from an SAP perspective, any IT group that is investigating SOA will find value in this book -- as it describes how SOA impacts different layers of the IT stack (from persistence to business objects, to process orchestration, and uesr interfaces). It also provides actual case studies.

SOA - reality today! - 2006-07-02
Reviewer Rating:
Being a student of business and information management, I had heard about SOA before, both from a technical perspective (XML, Web services) and from a business standpoint (shiny visions of flexible processes). This book is like the missing link between the two areas! It does not only tell you that SOA will change organizations but it also shows *how* exactly this is going to happen. The authors describe all relevenat aspects, starting from organizational change down to the SAP tools that can be used to model processes and to create your own service-oriented applications.
What surprised me most was that ESA - SAP's flavour of SOA - is business-ready today! This is illustrated with numerous real-world examples from a wide range of corporations. The case studies give a good idea of useful ESA applications and show how the transition to a service-oriented infrastructure could take place.
"Enterprise SOA" is suited for everybody interested in information management, even without any previous knowledge in the SOA field. After reading through the book, you'll finally know how SOA is changing the business environment and how SAP is bringing the concepts to life based on open standards. Although you won't know every technical detail, you'll have learned enough to plan your organization's future in a service-oriented world.
