Help Center/ Anti-DDoS Service/ Billing/ Billing Modes/ Yearly/Monthly Billing

Yearly/Monthly Billing

Updated on 2024-07-01 GMT+08:00

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 DDoS Mitigation 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

Table 1 lists the yearly/monthly billing items supported by different editions of the DDoS Mitigation service.

Billing Periods

The billing period of yearly/monthly DDoS Mitigation instance is determined by purchase duration (UTC+8). 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 DDoS Mitigation 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 purchase an instance of the basic edition at 15:50:04 on March 8, 2023. The billing resources include the number of protected IP addresses and service bandwidth. Your subscription is 3 months and you manually renew the subscription for another 3 months before the subscription expires. The billing details will be as follows:

  • The first billing period is from to 2023-03-08 15:50:04 to 2023-06-08 23:59:59.
  • The second billing period is from 2023-08-08 23:59:59 to 2023-09-08 23:59:59.

Figure 1 shows the billing calculation.

NOTICE:

The price in the figure is only an example. The actual price is based on that on the DDoS Mitigation console.

NOTE:

The price in the figure is for reference only.

Price Change After Specification Change

If the specifications of the current yearly/monthly DDoS Mitigation resources do not meet your requirements, you can modify the specifications on the DDoS Mitigation console. The system will calculate the DDoS Mitigation fee based on the following rules:

  • If you upgrade your DDoS Mitigation specifications, you need to pay the difference in price.
  • Resource specification downgrade: Currently, DDoS Mitigation instances do not support specification downgrade.

If you want to upgrade the specifications of BGP 10 GB billed by month (for example, CNY8700/month) to the BGP Pro 10 GB billed by month (for example, CNY9800/month), the remaining days of your current specifications are 20 days.

The formula is as follows:

Specification upgrade fee = (Monthly price of the new specifications/30 – Monthly price of the old specifications/30) x Remaining period

The additional fee is (9800/30-8700/30) x 20 = 733.34 CNY.

For more information, see Pricing of a Changed Specification.

Impacts of Expiration

Figure 2 describes the status of each stage of a yearly/monthly DDoS Mitigation instance. After a DDoS Mitigation 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 DDoS Mitigation instance lifecycle

Expiration Reminder

From the 7th day before a yearly/monthly DDoS Mitigation instance expires, the system will send an expiration reminder to the creator of the account by email, SMS, and internal message.

Impact of Expiration

If your yearly/monthly DDoS Mitigation instance is not renewed after it expires, it changes to the Expired state and enters a grace period. During the grace period, you can still use your DDoS Mitigation instance, but the following operations will be restricted:

  • Upgrading specifications

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

If the instance is not renewed after the retention period expires, the instance will be removed and data cannot be restored.

NOTE:
  • Huawei Cloud offers a 15-day grace period and a 15-day retention period.
  • For details about renewal, see Overview.
