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 Mongo instance with 4 vCPUs, 16 GB of memory, and 12 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

A yearly/monthly instance is billed for the purchased duration (UTC+8). The billing starts when you activated or renewed the subscription, and ends at 23:59:59 of the expiry date.

For example, if you bought a GeminiDB Mongo 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 Mongo instance with 4 vCPUs, 16 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 one more month before it expired. The billing items include instance specifications (vCPUs, memory, and nodes), storage, backup storage, and EIP bandwidth.

• The first billing cycle is from 15:50:04 on March 8, 2023 to 23:59:59 on April 8, 2023.
• The second billing cycle is from 23:59:59 on April 8, 2023 to 23:59:59 on 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 billed for 168 hours.

You need to pay in advance for each billing cycle. Each resource is billed separately.

Impact on Billing After Specification Changes

If the specifications of a yearly/monthly GeminiDB Mongo 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 increase instance specifications, you need to pay the difference in price.
• If you decrease instance specifications, Huawei Cloud will refund you the difference.

Decreasing instance specifications will affect instance performance. You are not advised to do so. Assume that you bought a yearly/monthly three-node GeminiDB Mongo instance with 4 vCPU and 16 GB of memory for one month on April 8, 2023 and increased its specifications to 8 vCPUs and 32 GB of memory on April 18, 2023. The old specifications cost $547.20 USD/month and the new specifications $1027.20 USD/month. The calculation formula is as follows:

Price difference = Price of new specifications x Remaining period – Price of old specifications x 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 fee for increasing specifications is $315.89 USD (1027.20 x 0.6581 – 547.20 × 0.6581).

For more details, see Pricing of a Changed Specification.

Impact of Expiration

Figure 3 shows the statuses a yearly/monthly GeminiDB Mongo instance throughout its lifecycle. 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

• The system will send you a reminder 30 days, 15 days, 7 days, 3 days, and 1 day before a yearly instance expires to remind you to renew the subscription.
• The system will send you a reminder 15 days, 7 days, 3 days, and 1 day before a monthly instance expires to remind you to renew the subscription.

to the creator of the Huawei Cloud account by email, SMS, and in-app message.

Impact of expiration

If your yearly/monthly GeminiDB Mongo 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 GeminiDB Mongo instance but cannot:

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

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

If the yearly/monthly GeminiDB Mongo instance is not renewed when the retention period expires, it will be released and data cannot be restored.

• For details about the renewal, see Overview.
