SESSION DESCRIPTION After years of hype and seemingly few deployments, this session highlights several real-world examples from today's leading enterprises implementing transaction-based Web services. The session answers critical questions for enterprises investigating Web services of their own, including: What are the major players really doing? What standards are considered practical for use? What architectural and infrastructure considerations are critical for success? Focusing on four detailed, real-world organizational examples from planning, development, testing, deployment, and finally from operational management, this session is a practical field guide to today's non-trivial Web service deployments and those steps taken to ensure their success.
