An AS configuration defines the specifications of the ECS instances to be added to an AS group. The specifications include the ECS image and system disk size.

Scenarios

When you create an AS group, create a new AS configuration or use an existing AS configuration.
Create the required AS configuration on the Instance Scaling page.
Change the AS configuration on the AS group details page.

Methods

If you create an AS configuration from an existing ECS instance, the vCPU, memory, image, disk, and ECS type are the same as those of the selected instance by default. For details, see Creating an AS Configuration from an Existing ECS Instance.
Create an AS configuration from a new specifications template.
If you have special requirements on the ECSs for resource expansion, use a new specifications template to create the AS configuration. For details, see Creating an AS Configuration from a New Specifications Template.
