I have tried to deploy a Container App with Zone Redundant enabled. However from the azure portal it shows as 1 replica, where I expect it suppose to show 3 replicas at least? Refer to screenshot below:

Note that in App Service, when I opt for zone redundant, it will show as 3 instances, which make sense.

Whereas here its showing 1 replica only, how to confirm if my app has been replicated to 3 zones at least? Please advice.

    @John Wong Yek Hon ,

    Welcome to Microsoft Q&A platform!

    Thank you for your query. The zoneRedundant setting ensures that your app is distributed across multiple availability zones for fault tolerance. However, the replica count displayed in the portal reflects the active replicas, which are determined by your scaling rules.

    If you want at least three replicas running at all times, you can configure the minReplicas setting in your app’s scale configuration.

    For more detailed information on setting up zone redundancy in your Container Apps environment, please refer to the following documentation:
