The fees of an Anti-DDoS Proxy (Chinese Mainland) instance consist of the subscription fee of the instance and the pay-as-you-go fee of the features that you enable on the instance. This topic describes the billable items, expiration, and overdue payments of Anti-DDoS Proxy (Chinese Mainland) instances.
Type
Anti-DDoS Proxy (Chinese Mainland) provides two types of instances: Anti-DDoS Proxy Professional instances and Anti-DDoS Proxy Advanced instances. You can directly purchase a Professional instance in the Anti-DDoS Proxy (Chinese Mainland) console. However, you must apply for an Advanced instance with a business manager.
Profession mitigation plan: The mitigation capabilities are based on the basic protection bandwidth and burstable protection bandwidth that you specify when you purchase an instance.
Advanced mitigation plan: The basic protection bandwidth is 5 Gbit/s, and 2 advanced mitigation sessions are provided each calendar month.
NoteAdvanced mitigation leverages the anti-DDoS scrubbing centers of Alibaba Cloud in the current region to protect your services against DDoS attacks.
If the advanced mitigation sessions that are provided per calendar month are exhausted, you can purchase global advanced mitigation sessions. For more information, see Billing of advanced mitigation sessions.
Billing rules
The actual prices on the
Anti-DDoS Proxy (Chinese Mainland) buy page shall prevail.
Instance prices based on the smallest specifications
Professional instance:
USD 3,120/month
Advanced instance:
USD 2,880/month
The following table lists the smallest specifications of an instance of both types, which means that the smallest values are selected for all subscription items and no pay-as-you-go features are enabled.
Item | Professional instance | Advanced instance | Billing method | Description |
Basic Bandwidth | 30 Gbit/s | 5 Gbit/s | Subscription | The basic protection capability of the instance. This specification can be scaled up for Professional instances but not for Advanced instances. |
Burstable Bandwidth | 30 Gbit/s | Not supported | Pay-as-you-go | This specification provides extra protection for traffic that exceeds the basic bandwidth. The extra protection charges fees on a pay-as-you-go basis. |
Clean Bandwidth | 100 Mbit/s | 100 Mbit/s | Subscription | The maximum bandwidth that the instance uses to manage service traffic if no attacks occur. This specification can be scaled up. |
95th Percentile Burstable Clean Bandwidth | Disabled | Disabled | Pay-as-you-go | If the actual bandwidth is greater than the clean bandwidth and less than the 95th percentile burstable clean bandwidth, pay-as-you-go bills are generated. |
Request Rate | 3,000 | 3,000 | Subscription | The maximum number of HTTP and HTTPS requests that the instance can concurrently process per second if no attacks occur. This specification can be scaled up. Note We recommend that you specify this specification (clean QPS) based on your business requirements. If the actual request rate (QPS) of your service exceeds the clean QPS that you specify, packet loss may occur and some logs may fail to be recorded. |
95th Percentile Burstable QPS | Disabled | Disabled | Pay-as-you-go | If the actual QPS is greater than the clean QPS and less than the 95th percentile burstable QPS, pay-as-you-go bills are generated. |
Functional package | Standard Function | Standard Function | Subscription | Anti-DDoS Proxy (Chinese Mainland) supports Standard and Enhanced function plans. The Enhanced function plan supports advanced service access capabilities and DDoS mitigation capabilities. For more information, see Comparison of the standard and enhanced function plans. |
Domains | 50 | 50 | Subscription | The number of HTTP and HTTPS domain names that an instance can protect. This specification can be scaled up. For every 10 additional domain names, the total number of second-level domain names that are supported is increased by one. For example, if the number of domain names that can be protected by an instance is 50, the domain names can belong to a maximum of five second-level domain names. |
Ports | 50 | 50 | Subscription | The number of TCP and UDP ports that can be protected by the instance. This specification can be scaled up. |
Unit prices of scalable specifications
Basic Bandwidth
The actual unit price is subject to the buy page.

For example, if you specify 6,000 as the clean QPS when you purchase an instance, you must pay the following fee for the specified clean QPS per month based on the following formula:
(3,000-0) × 0 + (5,000-3,000) × 1.5 + (6,000-5,000) × 1.425 = USD 4,425

For example, if you specify 200 as the number of ports when you purchase an instance, you must pay the following fee each month for the ports based on the following formula:
(50-0) × 0 + (150-50) × 7.50 + (200-150) × 6.75 = USD 1,087.5
Billing rules for pay-as-you-go items
The following items generate pay-as-you-go bills only when the features are enabled and the conditions for generating fees are met:
Feature | Billing rule | Description |
Burstable Bandwidth | The burstable protection feature is billed on a daily basis. | The feature is supported only for a Professional instance. The burstable protection bandwidth determines the maximum capability of the instance to defend against DDoS attacks. If the bandwidth of DDoS attacks is greater than the basic protection bandwidth, burstable protection is triggered to mitigate the DDoS attacks. You are charged for the usage of burstable protection. For more information, see Billing of the burstable protection bandwidth feature. |
95th Percentile Burstable Clean Bandwidth | Both the daily 95th percentile metering method and the monthly 95th percentile metering method are supported. | The burstable clean bandwidth feature provides additional clean bandwidth for your instance. If spikes occur in your service traffic and the traffic exceeds the clean bandwidth of the instance during peak hours, the burstable clean bandwidth feature prevents access to your service from being limited. For more information, see Billing of the burstable clean bandwidth feature. |
95th Percentile Burstable QPS | Both the daily 95th percentile metering method and the monthly 95th percentile metering method are supported. | The burstable QPS feature provides additional QPS for your instance. If spikes occur in your service QPS and the QPS exceeds the clean QPS of the instance during peak hours, the burstable QPS feature can be used to prevent access to your service from being limited. For more information, see Billing of the burstable QPS feature. |
Instance expiration
Stage | Description |
Before expiration | Alibaba Cloud sends you text messages and emails seven, three, and one day before your instance expires to remind you to renew your subscription. |
