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.

Billing Items

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

Assume that you want to buy a three-node GeminiDB DynamoDB-Compatible instance with 2 vCPUs, 8 GB of memory, and 100 GB of storage. At the bottom of the page for buying an instance, price details (excluding the backup storage fee) will be displayed.

Figure 1 Example price

You are billed for:

• Selected specifications
• Storage

The backup space fee is not included. For details about the backup price, see Product Pricing Details.

Billing Cycle

The billing cycle of a yearly/monthly GeminiDB DynamoDB-Compatible instance is determined by the duration (UTC+8) you commit to the subscription. 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 bought a GeminiDB DynamoDB-Compatible instance for one month at 15:50:04 on March 8, 2023, the billing cycle is from 15:50:04 on March 8, 2023 to 23:59:59 on April 8, 2023.

Billing Examples

Assume that you bought a three-node GeminiDB DynamoDB-Compatible instance with 2 vCPUs, 8 GB of memory, 100 GB of storage, 110 GB (100 GB for free) of backup storage for one month at 15:50:04 on March 8, 2023 and renewed the subscription for another month before the instance expired.

• 15:50:04, March 8, 2023 to 23:59:59, April 8, 2023
• 23:59:59, April 8, 2023 to 23:59:59, May 8, 2023
  • From 23:59:59 on April 8, 2023 to 23:59:59 on May 1, 2023, 50 GB of free backup storage was used.
  • From 23:59:59 on May 1, 2023 to 23:59:59 on May 8, 2023, another 10 GB of backup storage was used, which was billed for 168 hours.

You will be billed for each billing cycle. Resources of the GeminiDB DynamoDB-Compatible instance are billed separately.

Figure 2 shows how the total price is calculated.

Impact on Billing After Specification Changes

You can change the specifications on the console to meet your service requirements. The system will recalculate the price and either bill or refund you the difference.

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

Downgrading instance specifications will affect instance performance. You are not advised to do so. Assume that you bought a yearly/monthly three-node GeminiDB DynamoDB-Compatible instance with 2 vCPUs and 8 GB of memory on April 8, 2023 and upgraded its specifications to 4 vCPUs and 16 GB of memory on the same day. The old specifications cost USD587.06/month and the new specifications USD981.62/month. The calculation formula is 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 in the formula is the number of remaining days in each calendar month divided by the maximum number of days in the calendar month. In this example, the remaining period is 0.6581 (12/30 + 8/31). The upgrade fee is USD259.66 (981.62 x 0.6581 – 587.06 x 0.6581).

For more details, see Pricing of a Changed Specification.

Impact of Expiration

Figure 3 shows the statuses of a yearly/monthly GeminiDB DynamoDB-Compatible instance. After an instance is purchased, it enters the valid period and runs normally during this period. If the instance is not renewed after it expires, before being deleted, it first enters a grace period and then a retention period.

Expiration reminder

From the 7th day before a yearly/monthly GeminiDB DynamoDB-Compatible instance expires, the system will send an expiration reminder to the creator of the Huawei Cloud account by email, SMS, and in-app message.

Impact

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

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

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

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

• For details about the renewal, see Overview.
