Contemporary SOA fosters intrinsic interoperability
Further leveraging and supporting the required usage of open standards, a vendor diverse environment, and the availability of a discovery mechanism, is the concept of intrinsic interoperability. Regardless of whether an application actually has immediate integration requirements, design principles can be applied to outfit services with characteristics that naturally promote interoperability.
When building an SOA application from the ground up, services with intrinsic interoperability become potential integration endpoints (Figure 3.8). When properly standardized, this leads to service-oriented integration architectures wherein solutions themselves achieve a level of intrinsic interoperability. Fostering this characteristic can significantly alleviate the cost and effort of fulfilling future cross-application integration requirements.
