This presentation was created for the SATURN conference series and does not necessarily reflect the positions and views of the Software Engineering Institute.

In this presentation, we demonstrate how reusable architectural decision models can support service-oriented architecture (SOA) and cloud design: We present an architectural decision modeling framework called SOA Decision Modeling (SOAD), which treats recurring architectural decisions as first-class architecture design artifacts. SOAD provides a technique to systematically identify such recurring decisions. We also present a reusable architectural decision model for SOA that was created with SOAD. This model separates long lasting platform-independent decisions from rapidly changing platform-specific ones; the alternatives in a conceptual model reference architectural patterns. SOAD has its roots in our industry projects conducted since 2001; it has been leveraged successfully by practitioners since 2006. SOAD is not only applicable to enterprise application, SOA, and cloud design, but also to other application genres and architectural styles. It supports use cases such as education, knowledge exchange, design method, review technique, governance instrument, and architecture change management.
