Elastic Load Balancing Documentation

Learn about Elastic Load Balancing.

Use Application Load Balancers for HTTP and HTTPS traffic. The load balancer routes based on the content of the request.

Use Network Load Balancers for TCP, UDP, and TLS traffic where extreme performance is required.

Use Gateway Load Balancers to deploy, scale, and manage virtual appliances, such as firewalls.

Use Classic Load Balancers to distribute incoming application traffic across multiple EC2 instances in multiple Availability Zones. Classic Load Balancers are the previous generation of load balancers from ELB. We recommend that you migrate to a current generation load balancer.
