Praise for Service-Oriented Architecture
‘This book provides a superb overview of the SOA topic. Marksand Bell provide practical guidance across the entire SOA lifecycle-from business imperatives and motivations to thepost-deployment business and technical metrics to consider. Withthis book, Marks and Bell demonstrate a unique ability to take thecomplex dynamics of SOA, and through an eloquent set of metaphors, models, and principles, provide an understandable and insightfulhow-to manual for both technical and business executives. This willbecome a required handbook for any organization implementing SOA.’
–Dan Bertrand, Enterprise Technology Officer & EDSFellow, EDS Corporation
‘A fundamental breakthrough in the business and technologyperspectives of SOA-this book belongs in every software developer, architect, and IT executive library. Marks and Bell demonstrate acreative and practical approach to building complex, service-oriented systems. I especially liked the hands-onperspective brought to multiple aspects of SOA. A must-have guidein the technology turbulence of the future.’
–Ariel Aloni, Chief Technology Officer, Sun Gard Data Management Solutions
‘This outstanding text gets straight to the heart of the matter, cutting through the hyperbole and discussing how to drive realbusiness value through SOA. It will certainly impact my behavior, our governance models, and, subsequently, the successful businessoutcomes we derive as we continue to embrace SOA. A must-read forbattle-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 thetechnology’-standards, technology stacks, operational monitoring, and the like. In this book, Marks and Bell expand beyond thetechnology to provide a refreshing business-driven perspective to SOA, connecting the dots between business requirements, architecture, and development and operations, and overlaying theseperspectives with tried-and-true governance techniques to keep SOAinitiatives on track. A must-read for those leading the charge toadopt SOA within their enterprise.’
–Brent Carlson, Chief Technology Officer, Logic Library andcoauthor of San Francisco Design Patterns: Blueprints for Business Software
‘Marks and Bell have captured a wealth of practical experienceand lessons learned in what has become the hottest topic insoftware development. In this book, they explain in detail whatworks and what does not, from procedural issues to technicalchallenges. This book is an invaluable reference for organizationsseeking the benefits of SOAs.’
–Dr. Jeffrey S. Poulin, System Architect, Lockheed Martin andauthor of Measuring Software Reuse: Principles, Practices, and Economic Models
‘One of the last things companies often consider whenimplementing a business solution such as SOA is the impact onpeople. Marks and Bell provide an in-depth look at ‘what has tochange’ from a process standpoint to make any SOA implementation asuccess. A great read for those considering to embark on anenterprise SOA and looking for the right mix of people, process, and products.’
–Alan Himler, Vice President of Product Management and Marketing, Logic Library
