SOA

Soa is a term with multiple meanings, but it is most commonly associated with Service-oriented architecture (SOA) in computer science. SOA is a design approach for building distributed applications as a collection of interoperable services. Each service implements a specific business capability and exposes a well-defined interface, enabling other services and applications to interact over standardized protocols such as HTTP or messaging. Key principles of SOA include loose coupling, abstraction, reusability, and governance, which together support integration across heterogeneous platforms and systems. Common patterns include orchestration, where a central process coordinates multiple services to perform a workflow, and choreography, where services interact in a coordinated way without a single controlling component. Implementations often involve service registries, contract-first design, and security and transaction management to ensure reliability and compliance.

Beyond technology, Soa can also appear as an acronym for other organizations, or as a proper name or place in various languages, depending on regional usage. When encountered in non-technical contexts, its meaning is typically clarified by surrounding information or capitalization (for example, SOA for an organization’s name or a geographic designation). Because of these multiple meanings, context is essential to determine which sense of Soa is intended.
