(Optional) Step 3: Unsubscribe from Services

In this development scenario, DataArts Studio, OBS, and DLI incur fees. If you configure notifications, you may be billed for the following service:

SMN: If you enable SMN notifications for your DataArts Studio modules, you need to pay for the notifications.

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

**Table 1** Unsubscription methods for services
Service	Billing	Unsubscription Method
DataArts Studio	DataArts Studio Billing	DataArts Studio instances support only the yearly/monthly billing mode. You can unsubscribe from the package by referring to Unsubscriptions.
OBS	OBS Billing	OBS supports pay-per-use and yearly/monthly billing modes. Packages cannot be unsubscribed. In this example, the pay-per-use billing mode is used. You can delete the created bucket after using it. In addition, DataArts Studio job logs and DLI dirty data are stored in an OBS bucket named dlf-log-{Project id} by default. You can delete the bucket after unsubscribing from DataArts Studio.
DLI	DLI Billing	If you do not purchase a dedicated queue, you will be billed for storage and the amount of data scanned. You will be billed for the amount of data scanned when you submit a job using the default queue, and no fee will be incurred if you do not use a queue. To stop yourself from being billed for storage, delete related data on the Data Management page on the DLI console.
SMN	SMN Billing	You pay only for what you use. After you unsubscribe from DataArts Studio, no notification will be generated. You can also delete the topics and subscriptions that have been generated.
