Overview of the SOA Design & Architecture Exam
S90.03 mandates that SOA architects and systems engineers master the design of service-oriented enterprise solutions through the implementation of standardized service models. Candidates must demonstrate proficiency in modeling service contracts, applying WS-* specifications, and integrating RESTful architectures within legacy and modern infrastructures. The syllabus requires expertise in designing enterprise service buses, managing service autonomy, and orchestrating complex workflows using WS-BPEL. Technical focus areas include service composition, state management, discovery mechanisms, and security policy enforcement. Practitioners must articulate the integration of XML schemas, SOAP messaging, and WSDL definitions while ensuring interoperability, scalability, and loose coupling across distributed cloud-based or on-premises heterogeneous environments.
