Question

A company is using AWS Fargate to deploy many containerized web applications to a VPC. The applications must all be reachable through various DNS names on the standard port for HTTPS traffic. The company uses an Application Load Balancer (ALB) to handle traffic to each of the applications. The company uses the AWS Cloud Development Kit (AWS CDK) to automate the deployment process. The company uses two types of CDK stacks. The company uses one common stack to build the VPC itself and other shared infrastructure. The company also uses a set of application-specific stacks that contain details and logic for each application. The company needs to correctly allocate ALB-related resources between the two types of stacks. Which combination of solutions will provide a repeatable allocation of resources to the common stack and application-specific stacks? (Choose three.)

Accepted Answer

Correct answer: A, D, F. With AWS CDK, shared load-balancing infrastructure belongs in the common stack while per-application routing lives in the application-specific stacks. Place the ALB listener (a single HTTPS listener on port 443 shared by all apps) in the common stack (A). Each application then owns its host-header listener rule (D) and its target group (F) in its application-specific stack, giving a repeatable allocation.
