1. API Description

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

This API is used to exit instances from standby status in the scaling group.

After exiting standby status, the instance enters running state and the CLB weight value is restored to the default value.
This API is used to call the Auto Scaling power-on/power-off API which may change the standby status, while the Cloud Virtual Machine server power on/off API will not affect it.
After instances exit standby status, the scaling group will raise the expected number of instances. The new expected number cannot exceed the maximum value.

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