Ever hear of the ODTUG Kaleidoscope? It's the yearly conference that's organized by the Oracle Developers Technical User Group (ODTUG). This year there will be a number of symposiums at the day before ODTUG starts.
Service-Oriented Architecture (SOA) is not about technology, although technology is used to implement it. The principles of reliability and accommodating unexpected changes at a manageable cost can be applied equally in any programming language. However, as with most things in life, not just software development, it is easiest to use a model that is supported by tools and inter-operable (the ability of two or more systems or components to exchange information and to use the information that has been exchanged).
In an enterprise application integration scenario, SOA Governance is about visibility and control during the entire service lifecycle; including design time, where this boils down to maximizing the investments made in building the service portfolio to ensure that it provides for interoperability, reusability and extensibility.
How to obtain high autonomy and low mutual dependencies of the functional entities in an organization with regard to message interaction and service exposure of SOA? In this pattern I'll describe a model for a federated multi-bus SOA-platform that satisfies the desired autonomies and low mutual dependencies in complex organizations.
