The following describes how to stop billing in pay-per-use, yearly/monthly, and discount package modes.

• Pay-per-use

  If you no longer use a GaussDB(DWS) cluster that is in pay-per-use mode, delete it and its resources to stop the billing. To do so, log in to the GaussDB(DWS) management console and go to the Clusters page. The following table lists the billable items of GaussDB(DWS).

  Table 1 GaussDB(DWS) billable items

  Billing Item	Description
  Data warehouse node	The billing will be stopped after the cluster is deleted. For details about how to delete a cluster, see Deleting a Cluster.
  Snapshot storage space	When a cluster is deleted, its automated snapshots are deleted, but its manual snapshots are retained. After you delete the manual snapshots, the billing is stopped. To delete the manual snapshots, log in to the GaussDB(DWS) management console and go to the Clusters page. If the manual snapshots are still retained after the cluster is deleted and the total snapshot size exceeds the free space, the excess part will be billed based on the OBS billing rate.
  (Optional) EIP and bandwidth	If a cluster has an EIP, select Release the EIP bound to the cluster. when deleting the cluster. The billing will be stopped after the EIP is released. If you do not release the EIP, it will be billed as per VPC EIP pricing rules.
  (Optional) DEK	If you have enabled the Encrypt DataStore function for a cluster and purchased a key on DEW, the key is not deleted after you delete the cluster. Manually unsubscribe from and delete the key to stop billing. To do this, log in to the DEW management console and choose Data Encryption Workshop > Key Pair Service.

• Discount packages

  The discount packages are a one-off payment, so billing stops when the service expires. If you want to unsubscribe from a package in advance, you can cancel your order and receive a full refund within 5 days of purchase. For details about how to unsubscribe from the package in advance, see Is Refund Supported?. If you do not unsubscribe from the package, the system does not refund the fees.

  In addition, you need to delete the corresponding cluster to avoid being billed pay-per-use charges. For details, see •Pay-per-use mode.

• Yearly/Monthly package

  GaussDB(DWS) clusters billed in yearly/monthly mode support unconditional unsubscription within five days from your purchase. If you do not unsubscribe from the package, the system does not refund the fees.
