The @aws-cdk/aws-elasticloadbalancing package provides constructs for configuring classic load balancers.

Configuring a Load Balancer

Load balancers send traffic to one or more AutoScalingGroups. Create a load balancer, set up listeners and a health check, and supply the fleet(s) you want to load balance to in the targets property.

 // Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
 Object lb = LoadBalancer.Builder.create(this, "LB")
         .vpc(vpc)
         .internetFacing(true)
         .healthCheck(Map.of(
                 "port", 80))
         .build();
 
 lb.addTarget(myAutoScalingGroup);
 lb.addListener(Map.of(
         "externalPort", 80));
 

The load balancer allows all connections by default. If you want to change that, pass the allowConnectionsFrom property while setting up the listener:

 // Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
 lb.addListener(Map.of(
         "externalPort", 80,
         "allowConnectionsFrom", List.of(mySecurityGroup)));
