Yearly/Monthly Billing

Application Scenarios

If you want to ensure resource stability over a certain period of time, yearly/monthly billing is a good choice for the following types of workloads:

• Long-term workloads with stable resource requirements, such as official websites, online malls, and blogs.
• Long-term projects, such as scientific research projects and large-scale events.
• Workloads with predictable traffic bursts, for example, e-commerce promotions or festivals.
• Workloads with high data security requirements

Billed Items

Yearly/Monthly CBR resources are billed based on the purchased duration. Any operations performed on the CBR resources will not affect their yearly/monthly charges. You are billed for the following items on a yearly/monthly basis.

Billed Usage Period

A yearly/monthly CBR resource is billed for the purchased duration. The billing starts from when you activated or renewed the subscription, and ends at 23:59:59 of the expiry date.

For example, if you purchased a one-month server backup vault on March 8, 2023, 15:50:04, the billed usage period was from March 8, 2023, 15:50:04 to April 8, 2023, 23:59:59.

Billing Examples

Suppose you purchased a 100-GB server backup vault for a month on March 8, 2023, 15:50:04, and renewed the subscription for one more month before the initial subscription expired. The following usage periods would be billed.

Price Change After Specification Change

If the specifications of a yearly/monthly CBR resource no longer meet your needs, you can change the specifications on the console. The system will recalculate the price and either bill or refund you the difference.

• If you upgrade your resource specifications, you need to pay the difference in price.
• If you downgrade your resource specifications, Huawei Cloud will refund you the difference.

Suppose you purchased a 100-GB server backup vault for a month on April 8, 2023 and expanded the vault capacity to 200 GB on April 18, 2023. The price of the original specifications was $20 USD/month, and that for the new specifications was $40 USD/month. The price difference will be calculated as follows:

Price difference for the specification upgrade = Price for the new specifications × Remaining period - Price for the original specifications × Remaining period

The remaining period is the remaining days of each calendar month divided by the maximum number of days in each calendar month.

In this example, Remaining period = 12 (Remaining days in April)/30 (Maximum number of days in April) + 8 (Remaining days in May)/31 (Maximum number of days in May) = 0.6581.

Cost of upgrade = $40 USD x 0.6581 - $20 USD x 0.6581 = $13.162 USD

Impact of Expiration

Figure 1 shows the statuses a yearly/monthly CBR resource can go through throughout its lifecycle. After a CBR resource is purchased, it enters the valid period and works normally during this period. If the resource is not renewed after it expires, before being deleted, it first enters a grace period and then a retention period.

Expiration Reminder

The system will send you a reminder (by email, SMS, or in-app message) 7 days before a yearly/monthly CBR resource expires to remind you to renew the subscription.

Impact of Expiration

If your yearly/monthly CBR resource is not renewed after it expires, it changes to the Expired state and enters a grace period.

If the yearly/monthly CBR resource is not renewed after the grace period ends, its status turns to Frozen and it enters a retention period. You cannot perform any operations on the resource while it is in the retention period.

If the yearly/monthly CBR resource is not renewed by the time the retention period ends, the resource will be released and data cannot be restored.
