Monitor and Alert + +Set up monitoring and alerts for: +- High rate limit hit rate (> 10%) +- Suspicious IPs with many rejections +- Redis connection failures + +### 4. Document Rate Limits + +Inform API consumers about rate limits: +- Include in API documentation +- Return rate limit info in response headers (custom implementation) +- Provide clear error messages + +### 5. Combine with Authentication + +Apply rate limiting after authentication for better control: + +```go +// Good: Authenticate first, then rate limit +app.Use(authMiddleware) +app.Use(rateLimitMiddleware) +``` + +### 6. Test Before Deploying + +Always test rate limits in staging before production: +```bash +# Load test with rate limiting enabled +ab -n 1000 -c 50 http://staging-api/endpoint +``` + +### 7. Plan for Failures + +Ensure rate limiter fails gracefully if Redis is unavailable (already implemented): +- Falls back to memory storage +- Logs errors but continues serving requests + +--- + +##
