+and load balancer that makes deploying microservices easy.  Traefik integrates
+with your existing infrastructure components (Docker, Swarm mode, Kubernetes,
+Marathon, Consul, Etcd, Rancher, Amazon ECS, ...) and configures itself
+automatically and dynamically.  Pointing Traefik at your orchestrator should be
+the only configuration step you need.")
