A county ECS service behind an Application Load Balancer must add tasks when each target is overloaded with requests. Which metric-driven scaling approach fits?
Select an answer to reveal the explanation.
Short Explanation
When the ALB starts handing each task a firehose of requests, grow the team—raise desired count off request-per-target, don’t just give one tired worker a bigger hat.
Full Explanation
Horizontal scaling of an ECS service adjusts desired task count based on load balancer request density such as ALBRequestCountPerTarget. Vertical CPU reservation alone, ignoring the ALB, or pinning a single task does not match request-driven horizontal scale for a multi-AZ web tier.
