Replacing AS Configuration in an AS Group

Scenarios

If you need to change the ECS specifications in an AS group, you need to change the AS configuration.

Effective Time of New AS Configuration

If the AS group has an in-progress scaling action, the new AS configuration will take effect only for instances scaled in later scaling actions.

For example, the current AS configuration of the AS group is as-config-A, and the new AS configuration is as-config-B. The instance configuration in the current scaling action is still as-config-A.

The instance configuration will change to as-config-B in the next scaling action.

Procedure

1. Log in to the management console.
2. Under Computing, click Auto Scaling. In the navigation pane on the left, choose Instance Scaling. Then click the AS Groups tab.
3. Click the name of the target AS group. On the Basic Information page, click Change Configuration to the right of Configuration Name.

   You can also locate the row containing the target AS group and choose More > Change AS Configuration in the Operation column.

4. In the displayed Change AS Configuration dialog box, select another AS configuration to be used by the AS group.
5. Click OK.
