You can change the configuration of an instance to meet temporary scaling needs.
Note
The temporary configuration change feature applies only to Alibaba Cloud instances.
Considerations
Before you change the configuration of an instance, note the following considerations:
When an instance is in temporary capacity, you cannot perform standard configuration changes, set storage auto-scaling, add standby instances, or change the deployment mode.
After you change the configuration of an instance, the incremental costs incurred during the configuration change are billed by the hour. You can view the costs on the order page.
If the temporary configuration is changed again to the original configuration, the temporary configuration change is ended and no incremental charges will be incurred.
Changing the configuration of an instance may cause brief service interruption. We recommend that you perform this operation during off-peak hours.
Prerequisites
You have the project owner or project admin permissions.
The instance is in the Running state.
