A. Run the applications behind private Application Load Balancers (ALBs) in separate VPCs. Create a public Network Load Balancer (NLB) in the centralized VPC. Create target groups for the private DNS names of the ALBs. Configure host-based routing to route application traffic to the corresponding target group through the NLB.
B. Run the applications behind private Application Load Balancers (ALBs) in separate VPCs. Create a public Network Load Balancer (NLB) in the centralized VPC. Create target groups for the private IP addresses of the ALBs. Configure host-based routing to route application traffic to the corresponding target group through the NLB.
C. Run the applications behind private Network Load Balancers (NLBs) in separate VPCs. Create VPC peering connections between the application VPCs and the centralized VPC. Create a public Application Load Balancer (ALB) in the centralized VPC. Create target groups for the private DNS names of the NLBs. Configure host-based routing to route application traffic between individual applications though the ALB.
D. Run the applications behind private Network Load Balancers (NLBs) in separate VPCs. Configure each NLB as an AWS PrivateLink endpoint service with associated VPC endpoints in the centralized VPC. Create target groups that include the private IP addresses of each endpoint. Create a public Application Load Balancer (ALB) in the centralized VPC. Configure host-based routing to route application traffic to the corresponding target group through the ALB. Most Voted
