Billing Items
EVS disks are billed based on the disk type, size, and usage duration. For details, see EVS Pricing Details.
Billing starts:
• You will be billed for the EVS disks right after you have purchased them, regardless of whether they are attached or not.
Billing stops:
• For a yearly/monthly disk, the billing stops after the disk is successfully unsubscribed from, and the refund is calculated as follows: Refund = Your actual payment - Amount due - Handling fees. For details, see How Do I View the Refund for My Resource Unsubscription?
• For a pay-per-use disk, the billing stops after the disk is successfully deleted.
Billing Modes
EVS disks can be billed on a yearly/monthly or pay-per-use basis.
• Yearly/Monthly is a prepaid payment method.
• Pay-per-use is a postpaid payment method. Although EVS disks are billed by the second, billing is calculated hourly. If the usage is less than an hour, you are billed based on the actual time consumed.

• EVS does not support the reduction of disk capacities. • EVS supports the expansion of disk capacities. Multiple pieces of billing records will be generated within a billing cycle (an hour) when an expansion succeeded. For example, if you expand the capacity of an EVS disk from 100 GiB to 200 GiB at 01:30:01, two billing records will be generated in the billing cycle from 01:00:00 to 02:00:00. One is the billing record generated for the 100 GiB from 01:00:00-01:30:00, and the other is the billing record generated for the 200 GiB from 01:30:01-02:00:00. |
