Rancher implements a managed load balancer using HAProxy that can be manually scaled to multiple hosts. A load balancer can be used to distribute network and application traffic to individual containers by directly adding them or “linked” to a basic service. A basic service that is “linked” will have all its underlying containers automatically registered as load balancer targets by Rancher.
