Enabling an AS Group

Scenarios

You can enable an AS group to automatically scale capacity in or out.

After an AS group is enabled, its status changes to Enabled. AS monitors the AS policy and triggers a scaling action for AS groups only in Enabled state. After an AS group is enabled, AS triggers a scaling action to automatically add or remove instances if the number of instances in the AS group is different from the expected number of instances.

• Only AS groups in the Abnormal state can be forcibly enabled. You can choose More > Forcibly Enable to enable an abnormal AS group. Forcibly enabling an AS group does not have adverse consequences.
• After you create an AS group and add an AS configuration to an AS group, the AS group is automatically enabled.
