Decoupled services refer to a software architecture design principle that emphasizes reducing dependencies between different components of a system. This approach allows individual services to operate independently, enhancing scalability, maintainability, and flexibility. By decoupling services, developers can update or modify one service without affecting others, leading to more efficient development processes and easier troubleshooting. This concept is particularly relevant in microservices architecture, where applications are built as a collection of loosely connected services. Decoupled services can improve collaboration among teams and facilitate the adoption of modern technologies and practices, ultimately resulting in a more robust software ecosystem.
