This topic describes how to enable a scaling group. Auto Scaling can scale ECS instances for a scaling group only when the scaling group is in the Enabled state.


  • The scaling group is in the Disabled state.
  • One of the following methods is used to specify an instance configuration source for the scaling group:
    • Specify a launch template.
    • Create and enable a scaling configuration.


  1. Log on to the Auto Scaling console.
  2. In the left-side navigation pane, click Scaling Groups.
  3. In the top navigation bar, select a region.
  4. Find the scaling group and choose more > Enable in the Actions column.
    The scaling group enters the Enabled state.
