This topic describes how to release pay-as-you-go instances manually or automatically.

Prerequisites

Only pay-as-you-go Elastic Compute Service (ECS) instances (including preemptible instances) and expired subscription instances can be released.
Important
  • After an instance is released, its data is deleted and cannot be recovered. We recommend that you create snapshots to back up data before you release the instance. For more information, see Create a snapshot for a disk.
  • After an instance is released, snapshots and images manually created from the instance are not affected.

Background information

  • Subscription instances that have not expired cannot be released. If you want to release a subscription instance that has not expired, you must convert it into a pay-as-you-go instance first. For more information, see Change the billing method of an instance from subscription to pay-as-you-go.
  • You can manually release expired subscription instances. If you do not renew an expired instance within a specific period of time, the instance is automatically released.
  • If economical mode is disabled for a stopped pay-as-you-go instance, you continue to be charged for the instance until it is released.
  • You can enable release protection for a pay-as-you-go instance to prevent irreversible data loss caused by accidental release operations. For more information, see Enable or disable release protection for ECS instances.
  • If the Release Disk with Instance feature is disabled for a disk attached to an instance, the disk is automatically converted into a pay-as-you-go data disk and retained when the instance is released. For more information, see Release a disk.
