Network load balancing is the distribution of traffic based on network variables such as ip address and destination ports. It is layer 4 tcp and below and is not designed to take into consideration anything at the application layer such as content type cookie data custom headers user location or the application behavior. Scaling up and down with high availability. Application load balancer vs network load balancer vs classic load balancer.

Elastic load balancing automatically distributes incoming application traffic. The network load balancing nlb feature distributes traffic across several servers by using the tcp ip networking protocol. Common features between the three load balancers. Application load balancer also operates at the request level layer 7 but provides more advanced routing capabilities than the classic and network load balancers.
