Web / Traefik Interview questions
What is the difference between Traefik and Nginx as reverse proxies?
Both can terminate TLS, load balance, and route by host or path, but they differ most in how configuration gets applied and how they fit into dynamic infrastructure.
| Traefik | Nginx |
| Auto-discovers services from Docker/Kubernetes/etc. | Requires manually written or templated config files |
| Reloads configuration live, no restart needed | Typically needs a reload signal after config changes |
| Automatic Let's Encrypt certificate management built in | Needs an external tool like Certbot for automation |
| Native container/orchestrator focus | General-purpose web server and proxy, broader use cases |
Nginx tends to win on raw throughput and decades of battle-tested tuning knobs, while Traefik wins on operational simplicity in environments where services come and go frequently, which is exactly the pattern in container orchestration.
A key operational difference between Traefik and Nginx is:
Nginx typically requires which extra tool for automated certificates?
