How to Create a Load Balancer with an HTTPS Listener


Posted by christopher0404 on 2020-11-12

Elastic Load Balancing automatically distributes your incoming traffic across multiple targets, such as EC2 instances, containers, and IP addresses, in one or more Availability Zones.

Elastic Load Balancing supports four types of load balancers:

  1. Application Load Balancers
  2. Network Load Balancers
  3. Gateway Load Balancers
  4. Classic Load Balancers

You can select the type of load balancer that best suits your needs.
