TheBeardedBearSAS API Gateway — Kong, Traefik, Patterns
API Gateway moderne pour routing, auth, rate limiting, observabilité.
Responsabilités
| Fonction | Outils |
|---|---|
| Routing (path, header, canary) | Kong, Traefik, Nginx |
| Auth (JWT, OAuth2, API keys) | Kong plugins, Traefik middleware |
| Rate Limiting (per-user/IP) | Redis-backed counters |
| Load Balancing | HAProxy, Traefik |
| Circuit Breaker | Resilience4j, Istio |
Stacks
Kong — Enterprise, plugins riches, K8s-native
Traefik — Cloud-native, auto-discovery
AWS API Gateway — Managed, serverless
Nginx — Performance max, self-hosted
Envoy — Service mesh (Istio), gRPC
Kong Config
services:
- name: payment-api
url: http://payment:8080
routes: [{ paths: ["/api/payments"] }]
plugins: [rate-limiting, jwt, prometheus]
Traefik Config
http:
routers:
payment:
rule: "PathPrefix(`/api/payments`)"
middlewares: [rate-limit, auth]
middlewares:
rate-limit:
rateLimit: { average: 100, burst: 50 }
Rate Limiting Algorithms
Fixed Window — Simple counter, bursty
Sliding Window — Rolling counter, lissé
Token Bucket — Flexible, burst toléré
Leaky Bucket — Output constant, strict
