== 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.<ref>{{Cite web|title=Interview d'Emile Vauge, créateur de Containous et Traefik|url=https://medium.com/@bluecoders/interview-emile-vauge-cr%C3%A9ateur-de-containous-et-traefik-e952b8ad1377|last=Bluecoders|date=2020-02-24|website=Medium|language=en|access-date=2020-05-13}}</ref> Vauge wanted to create a dynamic reverse proxy that would automatically manage traffic routing within modern containerized and cloud-native infrastructures.<ref>{{Cite web|title=Interview Emile Vauge créateur de Traefik · frenchgo.fr /ˈɡoʊfər/|url=https://frenchgo.fr/2018/12/interview-emile-vauge-createur-de-traefik/|website=frenchgo.fr|access-date=2020-05-13}}</ref>

In April 2019, TraefikEE was released<ref>{{Cite web|title=Containous Announces the General Availability of Traefik Enterprise Edition|url=https://containo.us/press/containous-announces-the-general-availability-of-traefik-enterprise-edition/|date=2019-04-18|website=Containous: Makes Networking Boring|language=en|access-date=2020-05-13}}</ref> as a commercial offering of Traefik providing scalability, high-availability, and additional security features combined with support agreements for enterprise customers.<ref>{{Cite web|title=Sponsored post by Containous: Introducing Traefik Enterprise Edition: We Made It Distributed|url=https://social.techcrunch.com/sponsor/unlisted/introducing-traefik-enterprise-edition/|website=TechCrunch|language=en-US|access-date=2020-05-13}}</ref>

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, [[Middleware|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.<ref>{{Cite web|title=Traefik 2.0 Supports TCP, Middleware, and New Routing Features|url=https://www.infoq.com/news/2019/11/traefik-routing-release/|website=InfoQ|access-date=2020-05-13}}</ref>

In May 2020, [[Scaleway]] launched [[Kubernetes Kapsule]], a [[CNCF]] certified platform, featuring Traefik as one of the available [[Ingress controllers]].<ref>https://www.infoq.com/news/2020/05/scaleway-kubernetes-kapsule/</ref>
