- Node
- The nodes defined by the load balancer are responsible for servicing the requests received through the load balancer's virtual IP. By default, the load balancer employs a basic health check that ensures the node is listening on its defined port. The node is checked at the time of addition and at regular intervals as defined by the load balancer health check configuration. If a back-end node is not listening on its port or does not meet the conditions of the defined active health check for the load balancer, then the load balancer will not forward connections and its status will be listed as "OFFLINE". Only nodes that are in an "ONLINE" status will receive and be able to service traffic from the load balancer.
