@krishnachaytanya: A reverse proxy is the only address the internet knows. Your real servers sit behind it on private IPs nobody outside can reach. Every request hits the proxy first. Anything it already has, it answers itself and your origin server never hears about it. Only the rest gets forwarded, over a private link. So a traffic flood hammers the proxy, not your app. And to the visitor it still looks like one server. This is what nginx, Cloudflare, HAProxy, Caddy and Envoy are doing. Reverse proxy vs forward proxy: a forward proxy hides the client from the server. A reverse proxy hides the server from the client.
