Service-Oriented Architecture
Service-Oriented Architecture (SOA) is a software design approach where applications are built as a collection of loosely coupled, interoperable services. Each service is a self-contained unit of functionality that can be accessed over a network, typically using standard protocols like HTTP and messaging formats like XML or JSON. SOA enables modular development, reuse of services across different applications, and easier integration of disparate systems.
Developers should learn SOA when building large-scale, distributed systems that require flexibility, scalability, and integration with legacy or third-party systems. It is particularly useful in enterprise environments where business processes need to be automated across multiple applications, such as in e-commerce platforms, banking systems, or supply chain management. SOA helps reduce redundancy, improve maintainability, and support agile development by allowing services to be developed and deployed independently.
