Application load balancer network load balancer.
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.
Additionally its support for host based and path based routing x forwarded for headers server name indication sni and sticky sessions makes the application load balancer ideal.
Has built in cloudwatch monitoring.
Oct 8 2019 application load balancers and network load balancers now support three new security policies for forward secrecy.
Protocols other than http not every web.

After the load balancer receives a request it evaluates the listener rules in priority order to determine which.
By combining two or more computers that are running applications into a single virtual cluster nlb provides reliability and performance for web servers and other mission critical servers.
An elastic load balancer elb is one of the key architecture components for many applications inside the aws cloud in addition to autoscaling it enables and simplifies one of the most important tasks of our application s architecture.
