In a scaling group, you can create multiple scaling configurations, but you can only apply one of these scaling configurations.

Background information

A scaling configuration includes many configuration items. You can obtain the overview of a scaling configuration by using the View Details function to ensure that an appropriate ECS instance template is applied.

Procedure

  1. Log on to the Auto Scaling Console.
  2. On the Scaling Groups page, click Manage in the Actions column.
  3. In the left-side navigation pane, select Instance Configuration Source.
  4. In the left-side navigation pane, select Instance Configuration Source. On the Scaling Configurations tab, locate the scaling configuration to be applied, and click View Details in the Actions column.
  5. If you decide to apply the scaling configuration, click Apply in the Actions column.
    Note After you apply a scaling configuration, the status of the other scaling configurations will switch to Inactive.

Result

After you apply a scaling configuration, ECS instances that are created later will be automatically based on the scaling configuration in a scaling group when the specified scaling condition is met.
