Microservices is an architectural style that structures an application as a collection of small, loosely coupled services. Each service is designed to perform a specific business function and can be developed, deployed, and scaled independently. This approach enhances flexibility and allows teams to work on different services simultaneously, improving overall productivity. By breaking down applications into microservices, organizations can achieve greater resilience and easier maintenance. Each service communicates over well-defined APIs, often using protocols like HTTP or gRPC. This modularity not only simplifies updates and scaling but also enables the use of diverse technologies across services, fostering innovation.
