For incoming requests to AWS Accounts, should we use Application load balancer or Classic load balancer?

Question

For incoming requests to AWS Account, when should we use Application load balancer or Classic Load Balancer? I understand that, if we use application load balancing, we would be able to do path based routing to specific port of EC2 instance or to respective container. Is that the only criteria?

Answer 1

You probably shouldn't use a Classic load balancer for a new application. The newer Application (L7) and Network (L4) load balancers are better on many aspects. Here's the feature comparison from AWS:
