API Gateway

An API Gateway is a server that acts as an intermediary between clients and a collection of backend services. It handles various tasks such as request routing, composition, and protocol translation, making it easier to manage multiple services. API Gateways are crucial in microservices architectures, where they provide a single entry point for client requests, simplifying the communication process and enhancing security. They also enable load balancing, caching, and rate limiting to improve performance and reliability.
