Releases a pay-as-you-go Elastic Compute Service (ECS) instance or an expired subscription ECS instance. You can configure parameters to specify whether to release the disks attached to the instance or retain the disks as pay-as-you-go disks.
Operation description
**
Warning After an instance is released, all physical resources used by the instance are recycled. Relevant data is erased and cannot be restored.

Precautions
When you release an instance, manual snapshots of the cloud disks are retained. The settings configured during the creation of the instance determine whether the cloud disks attached to the instance and automatic snapshots are released. Before you release the instance, you can call the DescribeDisks operation to query the parameter settings for the cloud disks attached to the instance and the automatic snapshots.
- The cloud disks for which
DeleteWithInstanceis set to false are retained as pay-as-you-go disks after the instance is released. The cloud disks for which DeleteWithInstance is set to true are released along with the instance. - If
DeleteAutoSnapshotis set to false for a cloud disk attached to the instance, the automatic snapshots of the cloud disk are retained when the instance is released. If DeleteAutoSnapshot is set to true for the cloud disk, the cloud disk is released along with the instance.
