History
Traefik was created in 2015 by Emile Vauge to manage the incoming traffic for thousands of microservices. At that time, automating the routing configuration of ingress traffic to such dynamic infrastructures at this scale didn’t exist. Vauge wanted to create a dynamic reverse proxy that would automatically manage traffic routing within modern containerized and cloud-native infrastructures.

In April 2019, TraefikEE was released as a commercial offering of Traefik providing scalability, high-availability, and additional security features combined with support agreements for enterprise customers.

Traefik 2.0 was released in November 2019 with a number of core changes and new features. With the release, features such as SNI and Layer 4 (TCP) support were added. In addition, middlewares were introduced enabling chain rule-based behaviors along with support for advanced deployment patterns such as canary releases, A/B testing and traffic mirroring.
