The emergence of service-oriented architecture (SOA) as an approach for
integrating applications that expose services presents many new
challenges to organizations resulting in significant risks to their
business. Particularly important among those risks are failures to
effectively address quality attribute requirements such as performance,
availability, security, and modifiability. Because the risk and impact
of SOA are distributed and pervasive across applications, it is
critical to perform an architecture evaluation early in the software
life cycle. This report contains technical information about SOA design
considerations and tradeoffs that can help the architecture evaluator
to identify and mitigate risks in a timely and effective manner. The
report provides an overview of SOA, outlines key architecture
approaches and their effect on quality attributes, establishes an
organized collection of design-related questions that an architecture
evaluator may use to analyze the ability of the architecture to meet
quality requirements, and provides a brief sample evaluation.
