Description
"This book performs a valuable service for managers seeking to harness the business potential of Web services technology. Bringing a real practitioner's experience to the task, Anne carefully walks managers through the fundamentals of Web services technology. She does a superb job of helping managers understand this technology so that they can move with sure footing and avoid potentially harmful stumbles along the way." --From the Foreword by John Hagel III and John Seely Brown Written for business and technology managers, Web Services: A Manager's Guide illuminates the potential of Web services for application integration. It describes the essentials of supporting technologies and shows how they can be built into a Web services infrastructure that is high-performance, robust, and cost-effective. Realistic in approach, this book offers a readable definition of Web services and non-technical explanations of key technologies and standards. The author explores the scenarios and applications that would benefit most from Web services and offers guidelines for making an informed decision about which Web services products are right for your company's needs.
