Traefik is an open-source edge router built specifically for cloud-native and containerized environments. Its core strengths lie in automatic service discovery, dynamic routing, and load balancing. It seamlessly integrates with mainstream orchestration systems like Kubernetes and Docker, incorporates automatic HTTPS, and offers rich middleware capabilities. This significantly simplifies microservices network management and adapts to containerized application traffic scheduling needs across businesses ranging from small and medium-sized enterprises to large enterprises.
Developed by Emile Vauge in 2016, this project was renamed Traefik Labs and maintained by Containous starting in 2020. Leveraging its “zero manual routing configuration” capability in cloud-native scenarios, it has become a popular choice for reverse proxies and Ingress controllers within the container ecosystem, widely adopted in microservices architectures and edge computing scenarios.
