Manage scheduled tasks

A scheduled task scales out or scales in KEC instances in a scaling group at a specified time based on the predictable changes of business load.

You can create, modify, and delete scheduled tasks in the Auto Scaling console.

Create a scheduled task

To create a scheduled task, you must specify the start time, and the minimum, maximum, and expected numbers of KEC instances in the scaling group. When the specified time arrives, Auto Scaling adjusts the number of KEC instances in the scaling group based on the configuration.

You can create a scheduled task that is executed only once or periodically.

1. Log in to the Auto Scaling console.

2. In the left navigation pane, click Scaling Group.

3. Select a region from the top navigation bar.
