“API traffic control” usually means managing how much traffic your API accepts and how it behaves under load. Common controls include:
- Rate limiting: cap requests per user/IP/key per time window
- Throttling: slow down clients when they exceed limits
- Burst control: allow short spikes, but not sustained overload
- Quotas: monthly/daily usage limits
- Concurrency limits: cap simultaneous in-flight requests
- Load balancing: distribute traffic across instances
- Circuit breakers: stop sending traffic to failing dependencies
- Backpressure: signal clients or upstream systems to reduce load
- Caching: reduce repeated requests
- Autoscaling: add capacity as demand grows
Typical enforcement points:
- API gateway / reverse proxy: best place for rate limits and auth-based quotas
- Application layer: finer-grained per-endpoint or business-rule limits
- CDN/WAF: protect against abuse and DDoS-like traffic
- Service mesh: internal service-to-service traffic control
Example policies:
- 100 requests/minute per API key
- 10 concurrent requests per user
- 1,000 requests/day per tenant
- Higher limits for paid tiers
If you want, I can help with one of these specifically:
- Designing API traffic control
- Implementing rate limiting in a framework
- Choosing tools like NGINX, Kong, Envoy, AWS API Gateway
- Writing a policy for your API
