1. API Description

Domain name for API request: as.tencentcloudapi.com.

This API is used to delete CVM instances from a scaling group. Instances that are automatically created through AS will be terminated, while those manually added to the scaling group will be removed and retained.

If the number of remaining IN_SERVICE instances in the scaling group is less than the minimum capacity, this API will return an error.
However, if the scaling group is in DISABLED status, the removal will not verify the relationship between the number of IN_SERVICE instances and the minimum capacity.
This removal will unassociate the CVM from the CLB instance that has been configured for the scaling group.

A maximum of 20 requests can be initiated per second for this API.

Note: This API supports Finance regions. If the common parameter Region is a Finance region, a domain name with the Finance region needs to be specified, for example: as.ap-shanghai-fsi.tencentcloudapi.com
