When deploying a back end application you might need to have multiple instances for handling large traffic. A load balancer is used to manage these large number of requests between the multiple servers. Layer 7 load balancing operates at the high‑level application layer.

The server receives the request and sends back the response to the load balancer which forwards the response to the client over port 80.

It can act as both layer 7 and layer 4 load balancer.
