Create Application Load Balancer

First, let’s create an Application Load Balancer (ALB). To create the ALB, we need to initialize the applicationLoadBalancer object within the constructor:

   this.applicationLoadBalancer = new ApplicationLoadBalancer(this, "Alb",
       ApplicationLoadBalancerProps.builder()
           .build());

Next, set the name for the Application Load Balancer (ALB) to ECommerceAlb using:

.loadBalancerName("ECommerceAlb")

As mentioned earlier, we will not expose the Application Load Balancer (ALB) and Network Load Balancer (NLB) to the internet outside of the VPC. Therefore, we will configure them as follows:

   .internetFacing(false)
   .vpc(nlbStackProps.vpc())
