SOA is an architecture, and thus fulfills requirements across the business. However, in many cases, it remains an unknown venture -- even across IT organizations. In the latest issue of SOA Magazine, Tyson Brooks, PMP, urges SOA proponents to proactively undertake the "communication, outreach, training, and preparation for SOA
in the IT and management community."
Brooks summarized the key aspects of SOA-based architecture into four key areas:
Services can include both business processes and IT services, and can exist at all levels of the architecture. "This is a deliberate expansion of the conventional understanding of SOA in the IT world and reflects the broader SOA purpose."
Service components are characterized by how well they meet the definition of a service component, and by their level of complexity. "Service components can be, and often are, hierarchical or networked, aggregating lower level components into complex, high-level services."
Services components must be traceable throughout the organization's enterprise architecture. Mapping services must map to business processes and applications is essential.
Services, service components, and service level agreements (SLAs) should be defined, cataloged, and published. This helps make their capabilities known to potential customers.
