Timing policy: It is a preset task. According to the specified date and time, it executes the specified AS rules at the specified time for automatic expansion or reduction of computing resources.
Period policy: It is a preset task. According to the specified time, it executes tasks periodically by default.
Configuration cooldown period is the time it takes to cool down scaling activity, and the system starts calculating the cooldown duration after each scaling activity is triggered. Scaling activities triggered by alarm policies are denied by the AS group during the cooldown period, and scaling activities triggered by other types of policies such as scheduled and periodic policies are not restricted. However, it will re-calculate the cooldown time.
Executive action: Set the number of scaling actions and instances. The actions include:

Add: Instances are added to the AS group when a scaling activity is performed.

Reduce: Instances are removed from the AS group when a scaling activity is performed.
