How does AWS Autoscaling work? (the missing part)

when you put your instances on autoscale & set the minimum & maximum limit , does it scale to the maximum anyway or does it check for the threshold for each instance created by as and then spawn?

As in , 1 instance triggers an alarm for 90% cpu usage -> AutoScale creates 1 instance more (total 2) -> does it check for 90% cpu usage on both the instances & THEN create new instances or does it create new instances anyway after the cooldown time ?

Auto scaling will observe the average CPU usage of every instance and then decide if a new instance is needed or an existing can be shut down. This will ensure that you only use (and pay for) what you need.
