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

You are billed for the following items on a yearly/monthly basis.

If you want to purchase a replica set DB instance with 2 vCPUs, 4 GB of memory, five nodes, and 40 GB of storage for a duration of one month, the price will be as follows (excluding the backup space fee):

Figure 1 Example price

Billed Usage Period

A yearly/monthly DB instance 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 DDS DB instance on March 08, 2023, 15:50:04, the billed usage period is from March 08, 2023, 15:50:04 to April 08, 2023, 23:59:59.

Billing Examples

Suppose you purchased a one-month replica set DB instance (instance specifications: 2 vCPUs | 4 GB; number of nodes: 3; storage: 40 GB; backup space: 50 GB (40 GB for free)) on March 08, 2023, 15:50:04, and renewed the subscription for one more month before the initial subscription expired. The following usage periods will be billed:

• March 08, 2023, 15:50:04 to April 08, 2023, 23:59:59
• April 08, 2023, 23:59:59 to May 08, 2023, 23:59:59
  • From April 08, 2023, 23:59:59 to May 01, 2023, 23:59:59, 20 GB of free backup space was used.
  • From May 01, 2023, 23:59:59 to May 08, 2023, 23:59:59, another 10 GB of backup space was used, which was billed for 168 hours.

You will be billed for both usage periods. DDS resources are billed individually as follows:

Figure 2 shows how the total price is calculated.

The prices in the figure are just examples. The actual prices are those displayed on DDS Pricing Details.

Price Change After Specification Change

If the specifications of a yearly/monthly DB instance 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 DB instance specifications, you need to pay the difference in price.
• If you downgrade your DB instance specifications, Huawei Cloud will refund you the difference.

You are not advised to downgrade your DB instance to a lower specification because the instance performance may be affected. Suppose you purchased a one-month DB instance (2 vCPUs | 8 GB and 5 nodes) on April 08, 2023 and upgraded the instance specifications to 4 vCPUs | 16 GB and 5 nodes on April 18, 2023. The price of the original specifications was $332.05 USD/month, and that for the new specifications was $787.73 USD/month. The price difference will be calculated as follows:

Price difference for the specification upgrade = Price for the new specifications × Remaining period x Number of nodes - Price for the original specifications × Remaining period x Number of nodes

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 = $787.73 USD x 0.6581 x 5 – $332.05 USD x 0.6581 x 5 = $1499.42 USD

Impact of Expiration

Figure 3 shows the statuses a yearly/monthly DB instance can go through throughout its lifecycle. After a DB instance is purchased, it enters the valid period and runs normally during this period. If the DB instance 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 DB instance expires to remind you to renew the subscription.

Impact of Expiration

If your yearly/monthly DB instance is not renewed after it expires, it changes to the Expired state and enters a grace period. During the grace period, you can access the DB instance but cannot:

• Change instance specifications.
• Change the billing mode from yearly/monthly to pay-per-use.
• Unsubscribe from the DB instance.

If the yearly/monthly DB instance 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 DB instance while it is in the retention period.

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

• During the retention period, you cannot access or use your DB instance but data stored in it can be retained. The retention period for the Huawei Cloud International website is 15 days.
• During the grace period, you can access and use only some resources of your DB instance. The grace period for the Huawei Cloud International website is 15 days.
• For details about renewal, see Overview.
