Deleting an AS Configuration

When you no longer use an AS configuration, you can delete it. An AS configuration can be deleted only when it is not used by any AS group. You can delete an AS configuration or multiple AS configurations in batches.

Procedure

Log in to the management console.
Under Computing, click Auto Scaling.
On the AS Configuration tab, locate the row containing the target AS configuration and click Delete in the Operation column to delete this AS configuration. You can also select multiple AS configurations to be deleted and click Delete in the upper part of the AS configuration list to delete them in batches.
