API Gateway Concerns
API Gateway Concerns (Stub)
Gateway centralizes cross-cutting concerns (routing, auth, rate limiting, aggregation, observability injection).
To Be Expanded
- Edge vs internal gateway
- Caching & request collapsing
- Canary / A/B routing
- Security headers enforcement
Quick List
| Concern | Gateway Role |
|---|---|
| Auth | Verify tokens early |
| Rate limiting | Protect origins |
| Observability | Inject trace IDs |
| Transformation | Normalize headers/payloads |
Maintainers: Expand with example config (Envoy / NGINX / Kong).
