Elastic Block Storage (EBS) can be used for data storage in most common scenarios. When you purchase a cloud box, you must purchase EBS resources. This topic describes the billing of EBS resources in a cloud box.
Billing
You can use the following two types of cloud disks as EBS resources in a cloud box:
- Standard SSDs: a type of high-performance cloud disk that provides consistent high random IOPS and high data reliability.
- Enhanced SSDs (ESSDs) of performance level 0 (PL0): a type of ultra-high-performance cloud disk based on the next-generation distributed block storage architecture. A PL0 ESSD can provide up to 10,000 random read/write IOPS and low one-way latency.
EBS resources are billed based on the unit price, capacity, and subscription duration of the cloud disk that you purchase. Formula: Fees for EBS resources = Capacity of the cloud disk × Unit price of the capacity × Subscription duration.
| Disk type | Unit price | Capacity | Subscription duration |
|---|---|---|---|
| SSD | View the unit price of the capacity in the CloudBox console. |
| Yearly subscription. If you purchase a cloud box for the first time, the initial subscription duration must be three or five years. |
| ESSD | View the unit price of the capacity in the CloudBox console. |

Payment
The fees for EBS resources and other resources purchased in the same cloud box order are paid together. The subscription billing method is supported. You can select All Upfront or Half Upfront as the payment option.
- All Upfront: You must make a one-time full payment at the time of purchase.
- Half Upfront: You can pay 50% of the fees first, and then equally pay the rest by month.
After you accept the purchased cloud box, Alibaba Cloud generates bills on the first day of each month based on the remaining unpaid fees and subscription duration. The amount of each monthly bill is the same. Make sure that you have sufficient balance within your account to pay the bills at the earliest opportunity. If you do not pay the bills within seven calendar days after you receive the bills, your cloud box cannot provide services normally.
