"By delivering SAP's next-generation applications based on a Services-Oriented Architecture, SAP is at the forefront of making Web services work for the enterprise. The Enterprise Services Architecture enables unprecedented flexibility in business process deployment, allowing companies to execute and innovate end-to-end processes across departments and companies, with minimum disruption to other systems and existing IT investments. This strategy comes to life with SAP NetWeaver, which is the technological foundation of the Enterprise Services Architecture. It provides easy integration of people, information, and systems in heterogeneous IT environments and provides a future proof application platform. Enterprise SOA
provides readers with the architectural blueprints and SOA-driven project management strategies that are required to successfully adopt SOA on an enterprise level."
Dr. Peter Graf, SVP Product Marketing, SAP
The SOA principles outlined in this book enable enterprises to leverage robust and proven middleware platforms, including CORBA, to build flexible and business-oriented service architectures. The authors also clearly describe the right strategies for using Model Driven Architecture (MDA) to manage SOA Service Repositories in a platform-independent way, enabling enterprises to better address the problem of heterogeneity at many levels. The Object Management Group was created just to address this central problem of integration in the face of constantly changing heterogeneity and platform churn, so I strongly recommend this book for the bookshelf of every enterprise architect and developer.

Enterprise SOA provides strategies that help large enterprises to increase the agility of their IT systemsone of the most pressing issues of contemporary IT. Covering both a business and architectural view, these strategies aim to promote the implementation of an IT infrastructure that can serve as a base for the development of truly flexible business processes. This book covers its subject with great profoundness based on real world evidence. It is in the interest of everybody involved with software architectureparticularly for anybody who intends to establish a Service-Oriented Architectureto read this book.

"...The SOA principles described in this book are the foundation on which enterprises can build an IT architecture that will satisfy today's most important IT requirementsagility and flexibilityat affordable costs..."

Providing the roadmap for delivering on the promise of Service-Oriented Architecture
Enterprise SOA presents a complete roadmap for leveraging the principles of Service-Oriented Architectures to reduce cost and risk, improve efficiency and agility, and liberate your organization from the vagaries of changing technology.
- Benefit from the lessons of four enterprise-level SOA case studies from Credit Suisse, Halifax Bank of Scotland, and other world-class enterprises
- Make your business technology independent and manage infrastructure heterogeneity by focusing on architecture, not specific implementation techniques
- Recognize the technical and nontechnical success factors for SOA in the enterprise
- Define and communicate the economic value proposition of an SOA
- Apply pragmatic design principles to solve the problems of data and process integrity in an SOA environment
Whether you're a manager, architect, analyst, or developer, if you must drive greater value from IT services, Enterprise SOA will show you howfrom start to finish. About the Authors
DIRK KRAFZIG, KARL BANKE, and DIRK SLAMA have many years of experience in enterprise IT, including project management and distributed system design for large-scale projects. This book subsumes the knowledge of Service-Oriented Architectures that they have acquired since 1998, when they made their first steps toward this new architecture paradigm. About the Web Site
Web site www.enterprise-soa.com, provides a variety of supplemental material, including: articles, examples, and additional case studies.

This volume identifies pragmatic architectural strategies and project management techniques for the entire SOA lifecycle: planning, design, implementation, testing, rollout, and maintenance. It presents a complete roadmap for using service-oriented architectures to reduce cost and risk while improving efficiency and agility.
About the Author
About the Authors Dirk Krafzig
Dirk has been dealing with the challenges of enterprise IT and distributed software architectures throughout his entire working life. He devoted himself to SOA in 2001 when he joined Shinka Technologies, a start-up company and platform vendor in the early days of XML-based Web services. Since then, Dirk has acquired a rich set of real world experience with this upcoming new paradigm both from the view point of a platform vendor and from the perspective of software projects in different industry verticals.
Writing this book was an issue of personal concern to him as it provided the opportunity to share his experiences and many insights into the nature of enterprise IT with his readers.
Today, Dirk is designing enterprise applications and managing projects, applying the guiding principles outlined in this book. Dirk has a Ph.D. in Natural Science and an MSc in Computer Science. He lives in Düsseldorf, Germany, and is 39 years old, married, and the father of two children. Karl Banke
Software architecture has been with Karl since he programmed his first TRON-like game on the then state-of-the art ZX81 in the early 1980s. After graduating as a Master of Physics, he gained his commercial experience in various consulting assignments, mostly in the financial and telecommunications sector.
He moved through stages of consultant, technical lead, software architect, and project manager using a variety of object-oriented technologies, programming languages, and distributed computing environments. Soon realizing that he was too constrained as an employee in doing what he thought necessary in software development, he co-founded the company iternum in 2000, where he currently acts as a principal consultant and general manager.
Karl permanently lives in Mainz, Germany when not temporarily relocated by a current project. Dirk Slama
Having spent the last ten years at the forefront of distributed computing technology, Dirk has developed an in-depth understanding of enterprise software architectures and their application in a variety of industry verticals. Dirk was a senior consultant with IONA Technologies, working with Fortune 500 customers in Europe, America, and Asia on large-scale software integration projects. After this, Dirk set up his own company, Shinka Technologies, which successfully developed one of the first XML-based Web services middleware products, starting as early as 1999.
Dirk holds an MSc in computer sciences from TU-Berlin and an MBA from IMD in Lausanne. He is a co-author of Enterprise CORBA (Prentice Hall, 1999), the leading book on CORBA-based system architectures. Dirk is currently working as a solution architect for Computer Sciences Corporation in Zurich, Switzerland.
