Traefik Crash Course - Architecture, L7 & L4 Proxying, Weighted Round Robin, Enabling TLS 1.2/1.3

Traefik is an open-source reverse proxy written in GO and marketed as an Edge Router. It supports automatic TLS and HTTP/2 by default and other cloud native features. In this video I want to discuss Traefik as a reverse proxy and load balancer.
