Application load balancer network load balancer.

Scaling up and down with high availability. Application load balancer vs network load balancer vs classic load balancer. Network load balancer components a load balancer serves as the single point of contact for clients. The level 4 network load balancer only has tcp packets to work with so it can t read the http request headers like the application load balancer can.

Support connection draining when deregistering targets instances.
