A scaling activity will be canceled under such conditions that a conflict occurs when the scaling activity is triggered as the scheduled task starts or the requirement of the alarm scaling policy is met.
Causes of Conflict:
Other scaling activities are in progress.
The scaling group is under cooldown period.
Will the alarm scaling activity be rebooted if canceled?
No, the alarm scaling activity cannot be rebooted if canceled. If the requirements for alarm scaling are met, another alarm scaling activity will be triggered.
Scheduled task defines the expected, maximum and minimum group size, so the scaling group will will retry according to retry policy to ensure that the actual number of instances matches the expected number of instances.
Note：
Note: Disabled scaling group does not try any auto scaling activity. That's why such activity is not recorded as canceled scaling activity in the "Scaling Activity".
