Description
Praise for Service-Oriented Architecture
"This book provides a superb overview of the SOA topic. Marks and Bell
provide practical guidance across the entire SOA life cycle-from business
imperatives and motivations to the post-deployment business and technical
metrics to consider. With this book, Marks and Bell demonstrate a unique
ability to take the complex dynamics of SOA, and through an eloquent set of
metaphors, models, and principles, provide an understandable and insightful
how-to manual for both technical and business executives. This will become a
required handbook for any organization implementing SOA."—Dan Bertrand,
Enterprise Technology Officer & EDS Fellow, EDS Corporation
"A fundamental breakthrough in the business and technology perspectives of
SOA-this book belongs in every software developer, architect, and IT executive
library. Marks and Bell demonstrate a creative and practical approach to
building complex, service-oriented systems. I especially liked the hands-on
perspective brought to multiple aspects of SOA. A must-have guide in the
technology turbulence of the future."—Ariel Aloni, Chief Technology
Officer, SunGard Data Management Solutions
"This outstanding text gets straight to the heart of the matter, cutting
through the hyperbole and discussing how to drive real business value through
SOA. It will certainly impact my behavior, our governance models, and,
subsequently, the successful business outcomes we derive as we continue to
embrace SOA. A must-read for battle-scarred SOA veterans and fledgling
architects alike."—Christopher Crowhurst, Vice President and Chief
Architect, Thomson Learning
"Too often, SOA has been perceived as 'all about the technology'-standards,
technology stacks, operational monitoring, and the like. In this book, Marks
and Bell expand beyond the technology to provide a refreshing business-driven
perspective to SOA, connecting the dots between business requirements,
architecture, and development and operations, and overlaying these
perspectives with tried-and-true governance techniques to keep SOA initiatives
on track. A must-read for those leading the charge to adopt SOA within their
enterprise."—Brent Carlson, Chief Technology Officer, LogicLibrary and
coauthor of San Francisco Design Patterns: Blueprints for Business
Software
"Marks and Bell have captured a wealth of practical experience and lessons
learned in what has become the hottest topic in software development. In this
book, they explain in detail what works and what does not, from procedural
issues to technical challenges. This book is an invaluable reference for
organizations seeking the benefits of SOAs."—Dr. Jeffrey S. Poulin, System
Architect, Lockheed Martin and author of Measuring Software Reuse:
Principles, Practices, and Economic Models
"One of the last things companies often consider when implementing a
business solution such as SOA is the impact on people. Marks and Bell provide
an in-depth look at 'what has to change' from a process standpoint to make any
SOA implementation a success. A great read for those considering to embark on
an enterprise SOA and looking for the right mix of people, process, and
products."—Alan Himler, Vice President of Product Management and
Marketing, LogicLibrary
