Thanks for the feedback.
But I am wondering if one of the AZ is gone why can’t ASG not been able to spin up two instances in the other AZ as we set a minimum cap to 2?
— There is a statement in the scenario “processing mission-critical workloads” this means that there shouldn’t be a downtime. If you would recreate this option in the AWS Management Console, it takes a few minutes before ASG can spin up another instance in the remaining AZ. Therefore, if you need to run at least 2 EC2 instances to process mission-critical workloads, you must deploy 2 instances in each AZ. If there is an AZ outage, you would still have 2 instances running.
