Integration Appliance Enterprise Service Bus

Enterprise Service Bus Background

Most Enterprises have deployed an enterprise service bus for service mediation within a specific domain, especially when they have invested in a stack vendor suite for mainframe data integration, enterprise data integration or long-running transactions. As services attempt to be shared in a scalable way across domains, a SOA ESB tends to have security and performance feature gaps. The typical work-around leads to overly-complex deployment of multiple stack vendor products that are not interoperable with other best-of-breed infrastructure.

A Service Gateway enables services to be composed for sets of ESBs deployed across different domains adding cross-domain service mediation, threat prevention, security policy enforcement, AAA functions and are generally used for shorter-running transactions.

Intel Solution

The Intel^® Expressway Service Gateway simplifies deployment of sophisticated cross-domain integration scenarios using a soft-appliance form factor that makes development, deployment and management easier. The unique solution combines a sophisticated BPEL based visual workflow designer (not found in ESBs) with an appliance run-time security enforcement framework. Due to its appliance like management, ground-up security oriented design, stateless processing and very high performance; Intel Expressway Service Gateway is often used as a cross-domain ESB or as a Gateway co-processor in front of an ESB.

Typical ESB capabilities addressed

• Data routing
• Data transformation
• Protocol transformation
• Service naming mapping
• Synchronous & Asynchronous Message processing
• Transaction management
• Coordination of implementation services (“services orchestration”)
• Security management
