A company recently launched an application that is more popular than expected. The company wants to ensure the application can scale to meet increasing demands and provide reliability using multiple Availability Zones (AZs). The application runs on a fleet of Amazon EC2 instances behind an Application Load Balancer (ALB). A DevOps engineer has created an Auto Scaling group across multiple AZs for the application. Instances launched in the newly added AZs are not receiving any traffic for the application. What is likely causing this issue?
