Example Concept: A load balancer receives client requests and forwards them to one of several backend servers based on a chosen algorithm. For instance, in a round-robin setup, the load balancer forwards each new request to the next server in line, cycling through the list of servers. This helps distribute the load evenly. Advanced load balancers can also perform health checks to ensure traffic is only sent to servers that are up and running, and they can provide SSL termination and session persistence features.
