Can you explain the role of API Gateways in microservices security?

Short answer: An API Gateway serves as a reverse proxy that routes requests from clients to backend microservices, providing an essential layer of security.

Real-world example (ShopNest)

ShopNest’s API Gateway routes /orders to the Order service and /payments to Payment—clients talk to one entry point.
