Billable resources and their billing methods

|Image||Image fees are determined based on the image type and your usage.||
|EBS device (cloud disk or local disk)||Disk fees are determined based on the disk capacity and usage duration.
Note Local disks are tied to specific instance types and cannot be separately purchased. Prices of local disks are included in those of the instance type of instances to which the local disks are attached.

Change billing methods

When a subscription instance expires, the services provided by the instance may be affected. If you want to continue to use the instance, you must renew it within the specified period. Otherwise, instance resources such as vCPUs, memory, and disks are released and data stored on them is permanently lost. For more information about renewal, see Renewal overview.
