Yearly/Monthly Billing

Yearly/Monthly billing is a prepaid billing mode in which you pay before using resources. It is suitable when your resource requirements are fixed because you can pay less by using longer. In the yearly/monthly billing mode, we offer discounts to you. This topic describes the billing rules of yearly/monthly CBH resources.

Application Scenarios

If you want to ensure resource stability over a certain period of time, yearly/monthly billing is a good choice. The yearly/monthly billing mode is recommended for the following 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

CBH billing items include instance type and specifications. You are billed for the following items on a yearly/monthly basis.

Table 1 Billing items

Billing Item

Description

Specifications

Specifications of a CBH instance include the asset quantity and the CBH edition.

Billing Period

The billing period of a yearly/monthly CBH instance is determined by required duration (UTC+8:00). The billing starts when you activated or renewed the subscription (accurate to seconds), and ends at 23:59:59 of the expiry date.

For example, if you purchased a one-month CBH 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

Assume that you purchased a yearly/monthly CBH instance (specifications: 20 assets professional edition) at 15:50:04 on March 8, 2023. The billing resources include only CBH specifications, and the required duration is one month. Then, you renewed the subscription for one more month before the initial subscription expires. The following usage periods will be billed:

  • The first billing period: March 08, 2023, 15:50:04 to April 08, 2023, 23:59:59
  • The second billing period: April 08, 2023, 23:59:59 to May 08, 2023, 23:59:59

You need to pay for each billing period, and CBH resources are billed individually. The billing formula is shown in Table 2.

Figure 1 shows how the total price is calculated.

The price in the figure is for reference only. The actual calculation is based the price in the Product Price Details.

Price Change After Specification Change

If the specifications of a yearly/monthly CBH 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 CBH specifications, you need to pay the difference in price.
  • Resource specification reduction: CBH does not support specification reduction.

The price for the old edition is ¥700/month, and that for the new one is ¥1,050/month. The price difference will be calculated as follows:

Specification upgrade fee = New specification price × Remaining period - Old specification price × 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 = ¥1050 x 0.6581 – ¥700 x 0.6581 = ¥230.335.

Impacts of Expiration

Figure 2 shows the statuses a yearly/monthly CBH instance can go through throughout its lifecycle. After a CBH 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.

Figure 2 Periods of yearly/monthly CBH resources

Expiration reminder

From the 7th day before yearly/monthly CBH resources expire, the system will send an expiration reminder to the creator of the account by email, SMS, and internal message.

Impacts of expiration

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

If you do not renew your yearly/monthly CBH instance before the grace period ends, it goes into the retention period and its status turns to Frozen. You cannot perform any operations on such instances in the retention period.

If you still do not renew your yearly/monthly CBH instance before the retention period ends, the instance will be released, and the data cannot be restored.
