Service-Oriented Architecture (SOA) is a design approach where software components, or services, communicate with each other over a network. In SOA, services are designed to perform specific functions and can be accessed and used independently by other services or applications. This architecture promotes modularity, reusability, and interoperability by breaking down complex systems into smaller, manageable services.

Each service in an SOA is loosely coupled, meaning they are independent of each other and can be updated or replaced without affecting the entire system. This flexibility enables organizations to adapt quickly to changing business requirements and technology advancements.

SOA facilitates the creation of distributed systems that are scalable, flexible, and resilient. By decoupling components and promoting service reuse, SOA simplifies integration, enhances agility, and fosters innovation in software development.
