Difference between Classic and Elastic Load Balancer


I am learning about AWS elastic and classic load balancer. I understand what a load balancer does, but can someone please explain what the difference is between them?

I'm studying for a AWS certificate and I need to be able to explain the difference. Thanks in advance.


Solution

  • As others have said, you have three types of Elastic Load Balancer (ELB).

    You can select the appropriate load balancer based on your application needs. If you need flexible application management, we recommend that you use an Application Load Balancer. If extreme performance and static IP is needed for your application, we recommend that you use a Network Load Balancer. If you have an existing application that was built within the EC2-Classic network, then you should use a Classic Load Balancer.

    That's from the AWS ELB page, see a feature comparison and description of each service here: https://aws.amazon.com/elasticloadbalancing/features/
