Enterprise Open Source Software (OSS) Infrastructure
Nginx vs. Caddy vs. Traefik
All three proxies terminate TLS and route HTTP traffic, but they optimize for different operating models. Nginx favors raw performance and explicit configuration, Caddy automates certificates with sensible defaults, and Traefik discovers services dynamically in container environments. HTTP/3 support and TLS lifecycle handling vary.
Points clés
- Benchmark with your own payload sizes and connection reuse patterns.
- Evaluate certificate automation against your DNS and ACME constraints.
- Check HTTP/3 and TLS termination behavior on the versions you will run.
- Measure configuration reload behavior under load, since some proxies drop connections.
- Test dynamic service discovery if you run containers at scale.
- Review observability hooks: access logs, metrics, and tracing support.
- Plan for configuration drift if routes are generated rather than hand-written.
- Keep a simple fallback proxy configuration for emergency rollback.
Questions fréquentes
Which is fastest?
Nginx usually leads on raw throughput, but the gap is small relative to application time.
Is Caddy production ready?
Yes, and its automatic TLS is a strong default for smaller deployments.
Does Traefik replace Kubernetes ingress?
It can act as an ingress controller, though dedicated ingress options may fit better.
What matters most in practice?
Operational fit: certificate handling, configuration model, and debugging clarity.
