This topic describes the billing methods of Elastic Block Storage (EBS) devices and provides examples of how to calculate their fees.
- Cloud disks: Cloud disks are divided into system disks and data disks based on their intended purposes. Cloud disks are billed by category and capacity.
- Local disks: Local disks must be created together with instances and cannot be purchased
separately. The prices of local disks are included in the prices of instance types.
For information about instance families equipped with local disks, see Instance families.
|Billing method||Billing rule||Reference|
Price = Unit price of a cloud disk × Cloud disk capacity × Subscription duration
Price = Unit price of a cloud disk × Cloud disk capacity × Billing duration
- Cloud disks created along with an ECS instance use the same billing method as the ECS instance.
- If a cloud disk is created for and attached to an existing subscription instance, the billing method of the cloud disk may be subscription or pay-as-you-go. If a cloud disk is created for and attached to an existing pay-as-you-go instance, the billing method of the cloud disk must be pay-as-you-go.
- For independently created cloud disks that are not attached to instances, the billing method of the cloud disks must be pay-as-you-go.
- System disk: a standard SSD disk with a capacity of 50 GiB
- Data disk: an ultra disk with a capacity of 100 GiB
|Billing method||Billing condition||Price (USD)|
||(15.30/100 × 50 + 7.70) × 1 = 15.35|
||(0.03/100 × 50 + 0.02) × 24 = 0.84|
The billing methods of cloud disks can be changed from subscription to pay-as-you-go or from pay-as-you-go to subscription. For more information, see Change the billing method of a disk
