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.

Praise for Enterprise SOA
"As we started with the development of the e-Platform at the Winterthur, we knew that
there were still many questions to be answered. Today, we can look back at a process,
which has created the corresponding architectural guidelines, processes, and infrastructure
components. In the meantime, we are reaping the benefits of our strategy and are
transferring, step by step, our traditional application landscape into a loosely coupled SOA.
This forms, as well, the basis for our next step in the direction of Business Process
Management. This book clearly describes the many concepts that we painstakingly
developed at that time and answers the most important questions that are encountered on
the way to an adaptable application landscape for large-scale enterprises. From my point of
view, this is a book that should be read by all those who are considering remodeling their
application landscape."
Daniele Lisetto, Head Technical and Application Platforms, Winterthur Group
"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."
Dr. Helge Heß, Director Business Process Management, IDS Scheer AG
"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."
Martin Frick, Head of IT, Winterthur Group
"By delivering SAP's next-generation applications based on a Service-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.
