Understanding Reverse Proxies

Never expose a backend Node.js, Python, or Go application directly to the internet on port 80 or 443.

• A reverse proxy acts as an intermediary, sitting at the edge of your network to intercept user requests before they hit your application logic.
• It handles heavy lifting like SSL termination, gzip compression, and static file serving, freeing up your application to focus purely on executing business logic.
• Tools like Nginx and Traefik are built in C and Go to handle thousands of concurrent connections efficiently, providing a critical layer of defense against malicious traffic.
