The definitive guide to using Service-Oriented Architecture (SOA) and Web services technologies to simplify IT infrastructure and improve business agility. Renowned experts Eric Newcomer and Greg Lomow offer practical strategies and proven best practices for every facet of SOA planning and implementation. Newcomer and Lomow pick up where Newcomer's widely read Understanding Web Services left off, showing how to fully leverage today's latest Web services standards for metadata management, security, reliable messaging, transactions, and orchestration.

Along the way, they present specific approaches and solutions for a wide range of enterprise integration and development challenges, including the largest and most complex.

Coverage includes:

• Why SOA has emerged as the dominant approach to enterprise integration
• How and why Web services provide the ideal foundation for SOA
• Underlying concepts shared by all SOAs: governance, service contracts, Web services platforms, service-oriented development, and more
• Implementing service-level communications, discovery, security, data handling, transaction management, and system management
• Using SOA to deliver application interoperability, multichannel client access, and business process management
• Practical tutorials on WS-Security, WS-Reliable Messaging, WS-AtomicTransactions, WS-Composite Application Framework, WS-Addressing, WS-Policy, and WS-BPEL

Whether you're an architect, developer, or IT manager, Understanding SOA with Web Services will help you get SOA right—and achieve both the business and technical goals you've set for it.
