The Role of XML Gateways in SOA

Adopt “application networking” functionality to complete critical SOA tasks without programming

XML gateways manage message-level security, SLAs and performance for SOA. In contrast to conventional networking devices, XML gateways specialize in the application-level protocols rendered within XML or Web services messages. An XML gateway can rapidly inspect and process XML messages to efficiently perform a range of processes vital to SOA, including:

• Content routing
• Protocol switching and data transformation
• Identity authentication and privacy enforcement
• Schema validation

This white paper explains how, by delivering “application networking” functionality, XML gateways make it possible for SOA architects to complete mission-critical tasks without programming. Key tasks discussed include:

• Implementing security
• Optimizing performance
• Enabling advanced policy operations
