SOA

Service-Oriented Architecture (SOA) is an architectural style for building software applications as a collection of loosely coupled, interoperable services. Each service encapsulates a specific business capability and communicates with others through well-defined interfaces, commonly using SOAP, REST, or messaging protocols. SOA enables enterprise integration, reusability, and flexibility across heterogeneous systems.

SOA publishes 1 API on the APIs.io network. Tagged areas include SOA, Service-Oriented Architecture, Enterprise Integration, Web Services, and SOAP.

The SOA catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

SOA’s developer surface includes code examples and 10 more developer resources.
