(Optional) Step 9: Service Unsubscription

In this development scenario, DataArts Studio, OBS, MRS, and GaussDB(DWS) incur fees. If you configure notifications, you may be billed for the following services:

SMN: If you enable SMN notifications for your DataArts Studio modules, you need to pay for the notifications.
EIP: If you use an EIP for your DataArts Migration cluster or DataArts DataService Exclusive cluster, you need to pay for the EIP.

After the development is complete, unsubscribe from DataArts Studio and other related services and delete resources in a timely manner to avoid undesired fees.
