What are Envoy and Traefik?
Envoy
Envoy is a high-performance, open-source edge and service proxy designed for cloud-native applications and service meshes. It offers advanced load balancing, observability, and dynamic configuration.
- Service mesh data plane
- Dynamic xDS configuration
- Rich observability
- Advanced load balancing
Traefik
Traefik is a modern reverse proxy and load balancer that automatically discovers services and configures routing. It integrates natively with Docker, Kubernetes, and other orchestrators.
- Automatic service discovery
- Native Docker and Kubernetes support
- Let's Encrypt integration
- Live configuration reload
