Question

Your company runs a lightweight REST API in Azure Container Apps. Traffic is highly intermittent — the API receives no requests for hours during off-peak periods, then bursts of concurrent HTTP calls during business hours. Management wants to eliminate compute charges during idle periods while automatically handling burst traffic. Which scaling configuration should you apply to the container app?

Accepted Answer

Set the minimum replica count to 0 and configure an HTTP scale rule based on concurrent requests.

Answer

Set the minimum replica count to 1 and configure a CPU-based scale rule.

Answer

Deploy the app to a Dedicated workload profile with a fixed replica count of 2.

Answer

Set both minimum and maximum replica counts to 1 to guarantee availability.
