Suspending and Resuming Scaling

Use Cases

If you need to troubleshoot configuration or other issues related to the web application (such as resetting a password after shutting down the application, upgrading a service, etc.) and want to make changes to the application without triggering the automatic scaling process, you can suspend the scaling group and resume it after completion.

Suspending a Scaling Group

Operation

1. Open the auto scaling console.
2. Click Scaling Group in the left sidebar.
3. In the operation column of the scaling group list, click Disable.
   After setting, you can see the word Disabled in the Status list.

Notes

After a scaling group is disabled, the automatically triggered activities of the scaling group are not performed, but the restrictions of the scaling group are still in effect.

• Automatically triggered activities include:
  • Alarm Scaling
  • Scheduled Task
  • Health Examination
  • Manually Causing the Expected Number of Instances to Not Match
• Scaling group limitations include:
  • Manually removing instances is not subject to the minimum number of instances.
  • If the number of manually added instances exceeds the maximum number, the addition is not allowed.
  • Manually increasing the minimum or maximum number of instances does not trigger scaling activities.

Resuming Scaling Groups

If you have completed troubleshooting or operations during the period when the scaling group activities were suspended, you can resume the automatic scaling settings for your business.

1. Open the auto scaling console.
2. Click Scaling Group in the left sidebar.
3. In the operation column of the scaling group list, click Enable.
