What is an API Gateway, and how does it fit into microservices

rchitecture?

n API Gateway is a server that acts as an entry point for all client requests to the backend

services in a microservices architecture. It acts as a reverse proxy, routing requests from

clients to the appropriate microservice, handling common concerns such as security,

logging, monitoring, and rate-limiting.

How it fits into microservices architecture:

• It abstracts the complexity of interacting with multiple services and provides a unified

interface to clients.

• It helps with centralized control of common concerns, improving scalability and

maintainability.

• It simplifies the client-side by consolidating multiple service endpoints into a single

entry point.
