Real-world SOA tends to grow organically. That is, we often see business units, functional groups or geographically separated divisions having local SOA implementations that include registry, repository, service inventory, ESB, portals, and security infrastructure which are all based on the needs and trends of that local domain.


More often than not this is because these different domains have made significant investments in proprietary, integrated SOA technologies from major software vendors. While the integrated stack provides SOA for the local domain, it creates middleware heterogeneity and simply repeats the silo problem at the next level.  What is needed is a true cross-domain view of service oriented architecture that bridges these islands of integration.

This resulting vendor lock-in creates islands of non-interoperable software that is difficult to scale. What is needed is a cross-domain integration platform to exchange and aggregate key enterprise services like employees, financials, orders, vendors and customers across the entire organization, not just within a local domain.  This situation, known as Federated SOA, is the predominant trend seen in today's enterprise-wide SOA projects.  A high performance software appliance like Intel® SOA Expressway is uniquely suited to connect these SOA domains the enterprise.

Intel SOA Expressway combines a high performance workflow engine, native XML acceleration, appliance manageability and codeless design for designing a high volume, high throughput federated SOA. The end goal is to simplify application development for SOA applications that cross domain boundaries in large scale, high value environments.
