Create a scaling configuration

Last Updated: Apr 10, 2018

Auto Scaling automatically adds ECS instances into Auto Scaling groups according to the conditions you set when demands for your instances increase. In Create Scaling Configuration, you can specify the options of the ECS instances listed.

Note:

  • You cannot modify a scaling configuration once it is created. You can replace it with a new configuration if needed, you must update it with the new scaling configuration.
  • ECS instances created by the replaced scaling configuration work as usual.
  • You can create up to 10 scaling configurations for one Auto Scaling group, and only one scaling configuration can be at the Activated status.
