EVS Billing

You will be billed for the storage capacity based on the disk type and for how long you use a disk. There are yearly/monthly and pay-per-use billing modes, and you can change the billing mode if needed.

Item	Yearly/Monthly	Pay-per-Use
Billed usage period	Prepaid	Postpaid The disk usage is calculated by the second but billed every hour. If your usage is less than an hour, you are billed based on the actual duration consumed.
Billing for capacity expansion	Disk capacity can be expanded. You need to pay for the price difference.	Postpaid You will be billed for the new capacity after the expansion is complete.
Billing for performance change	The disk performance (throughput and IOPS) does not support yearly/monthly billing. For yearly/monthly EVS disks that allow you to configure the disk performance, yearly/monthly billing only applies to the disk capacity, and the disk performance is billed on a pay-per-use basis. This is also true after a performance change.	The disk performance can only be billed on a pay-per-use basis. The performance is billed on a pay-per-use basis after a performance change.
Billing for disk type change	You need to pay for the price difference.	The disk is billed on a pay-per-use basis after a disk type change.
