HAProxy vs Traefik: What are the differences?
Developers describe HAProxy as "The Reliable, High Performance TCP/HTTP Load Balancer". HAProxy (High Availability Proxy) is a free, very fast and reliable solution offering high availability, load balancing, and proxying for TCP and HTTP-based applications. On the other hand, Traefik is detailed as "Load Balancer for Microservices". Træfɪk is a modern HTTP reverse proxy and load balancer made to deploy microservices with ease. It supports several backends (Docker, Swarm, Mesos/Marathon, Kubernetes, Consul, Etcd, Zookeeper, BoltDB, Rest API, file...) to manage its configuration automatically and dynamically.
HAProxy and Traefik can be categorized as "Load Balancer / Reverse Proxy" tools.
"Load balancer" is the primary reason why developers consider HAProxy over the competitors, whereas "Kubernetes integration" was stated as the key factor in picking Traefik.
