Enterprise SOA
Designing IT for Business Innovation
Publisher: O'Reilly Media
Final Release Date: April 2006
Pages: 456

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.

SAPs SOA Blueprint

By melstrand

from Undisclosed

Comments about oreilly Enterprise SOA:

This book should be of special interest to SAP users, including developers, architects, business analysts, CEOs, and CIOs. It outlines SAPs roadmap for the future of SOA (Service Oriented Architecture). This is built around ESA (Enterprise Services Architecture), which is SAPs proposed means for building and linking services in a way that promotes maintainability and reuse. It relies heavily on model-driven development

(modeling is the "organizing principle" of ESA).

The authors include fairly extensive discussions of SAPs plans for the future. For

this reason, a better title might be _Enterprise SOA from SAPs Point of View_. However, the strategy outlined, and examples given, should also interest those not using SAP, in that it presents persuasive arguments for an architecture that could be used by organizations faced with extensive complexities in business operations and

therefore, supporting business software. It also brings out issues that such organizations will have to face, such as creating services that are maintainable and reusable. As the authors point out, flexibility in both business operations and

software will be especially necessary to be agile and adaptable in the future--in many

cases, multi-year projects are no longer practical.

Some readers might find the organization of the book a little frustrating if they try to read it from beginning to end without first skimming it, but it is a complex subject, and different ways of organizing the discussion will appeal to different

readers. One nice feature is a brief, high-level introduction to the basics of web services in an FAQ format (pp. 99ff.; pp 321 ff.). The latter reference includes a brief explanation of XML, schemas, and namespaces. Another nice feature is the examples (pp. 184ff., pp228ff., pp372ff., etc.).

A glossary of SAP terms and acronyms might enhance the appeal of the book to non-SAP users, although use of sites such as Google lessens this need somewhat.
