What is a Load Balancer?
Load balancer is responsible to distribute user requests (load) among the various back-end systems/nodes in the cluster. Each of these back-end machines runs a copy of your software and hence capable of servicing requests.
Another common responsibility is "health-check" where the load balancer uses the "ping-echo" protocol or exchanges heartbeat messages with all the servers to ensure they are up and running fine.
