A federated IT environment is one where resources and applications are united while maintaining their individual autonomy and self-governance. SOA aims to increase a federated perspective of an enterprise to whatever extent it is applied. It accomplishes this through the wide spread deployment of standardized and composable services each of which encapsulates a segment of the enterprise and expresses it in a consistent manner.
In support of increasing federation, standardization becomes part of the extra up-front attention each service receives at design time. Ultimately this leads to an environment where enterprise-wide solution logic becomes naturally harmonized, regardless of the nature of its underlying implementation.
Figure 1 – Three service contracts establishing a federated set of endpoints, each of which encapsulates a different implementation. When service-oriented solutions are built via the Web services technology platform, the level of attainable federation is further elevated because services can leverage the non-proprietary nature of the technologies themselves. However, even when using Web services the key success factor to achieving true unity and federation remains the application of design principles and standards.
