Description: API gateway routing is a fundamental process in microservices architecture and API management, responsible for directing API requests to the appropriate backend services. This mechanism acts as an intermediary between clients and services, allowing requests to be processed efficiently and securely. Upon receiving a request, the API gateway router evaluates the requested route and determines the corresponding backend service to which the request should be redirected. This process not only optimizes communication between clients and services but also enables the implementation of additional features such as authentication, authorization, and rate limiting. Furthermore, API gateway routing facilitates service version management, allowing developers to make changes to the backend without affecting clients. In a cloud environment, this approach becomes even more relevant as it allows for centralized scaling and management of multiple services, enhancing application resilience and availability. In summary, API gateway routing is essential for building modern applications, providing an abstraction layer that simplifies interaction between users and backend services.
