How to Implement Rate Limiting (Edge + App Level)
Rate limiting is one of the most underrated security controls in modern systems. In this video, I show how to properly apply rate limiting at two critical layers:
Edge / DNS Level (Cloudflare)
Block abusive IPs before they hit your server
Apply rate limits based on URL paths
Stop brute-force & bot traffic early
Application Level (Node.js)
Limit requests per IP
Block abusive users for a x-minute window
Protect APIs without affecting legitimate users
Why this matters
Prevent API abuse
Reduce server load & cloud costs
Improve reliability and uptime
Add a strong security layer with minimal effort
Best practice: Use Cloudflare + App-level rate limiting together
