API Gateway

Definition & Overview

An API Gateway serves as a single entry point for clients to access various microservices or backend systems. It acts as a reverse proxy, routing requests from clients to the appropriate services and aggregating their responses. API Gateways offer functionalities like authentication, authorization, rate limiting, and request transformation, enhancing security.

Additionally, they facilitate API versioning, monitoring, and analytics, enabling organizations to track usage patterns and diagnose issues effectively. By centralizing access control and enforcing consistent policies, API Gateways streamline API management and governance.

Furthermore, API Gateways support protocol translation, allowing clients to communicate with backend services using different protocols. This versatility ensures compatibility across diverse client environments and simplifies integration efforts. Overall, API Gateways play a crucial role in orchestrating interactions between clients and backend services.
