Presentation
Seven Steps to a Service-Oriented Evolution

The service-oriented paradigm supports modularized exposure of existing applications functionality to other applications as services. Such architectures are particularly applicable when multiple applications running on varied technologies and platforms have to communicate with each other. Adopting the paradigm is an evolutionary process where enterprises must embrace the architectural concepts and steadily incorporate them into existing applications, then take appropriate steps in upcoming implementations. The presentation describes the seven key steps involved in architecting solutions that can expedite evolution to the SOA paradigm.
