SOA
Service-Oriented Architecture (SOA) is a software design approach where applications are built as a collection of loosely coupled, interoperable services that communicate over a network. Each service is a self-contained unit of functionality that can be accessed independently and reused across different systems. This architecture promotes modularity, flexibility, and integration in enterprise environments.
Developers should learn SOA when building large-scale, distributed systems that require integration of diverse applications, such as in enterprise settings where legacy systems need to connect with modern services. It is particularly useful for scenarios requiring scalability, reusability of business logic, and standardized communication protocols like SOAP or REST, enabling easier maintenance and evolution of complex software ecosystems.
