Unlimited:
USD 11,560 per month

Specification name	Specification of the Insurance mitigation plan	Specification of the Unlimited mitigation plan	Billing method	Description
Clean bandwidth	100 Mbit/s	100 Mbit/s	Subscription	The maximum service traffic that can be processed by the instance when no attacks occur. You can increase the specification.
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.
Clean queries per second (QPS)	500	1,000	Subscription	The maximum number of HTTP and HTTPS requests per second that can be concurrently processed by the instance when no attacks occur. You can increase the specification. Note We recommend that you specify the clean QPS based on your business requirements. If the actual 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.

The Enhanced function plan supports advanced service access capabilities and DDoS mitigation capabilities. For more information, see Differences between the Standard and Enhanced function plans.
Number of domain names that can be protected	10	10	Subscription	The number of HTTP and HTTPS domain names that an instance can protect. For every 10 additional domain names, the total number of second-level domain names that are supported is increased by 1. If the number of domain names that can be protected by an instance is 50, the domain names can belong to up to 5 second-level domain names.
Number of ports	5	5	Subscription	The number of TCP and UDP ports that can be protected by an instance. You can increase the specification.

Unit price (

USD per QPS-month)

Insurance: 0 < QPS ≤ 500

Unlimited: 0< QPS ≤ 1,000

Insurance: 500 < QPS ≤ 5,000

Unlimited: 1,000< QPS ≤ 5,000

10,000 < QPS ≤ 50,000

1.275

50,000 < QPS ≤ 100,000

1.05

For example, you purchase an instance of the Insurance mitigation plan and specify 6,000 for the clean QPS. The fee for the specified clean QPS per month is calculated based on the following formula:

(500 - 0) × 0 + (5,000 - 500) × 1.5 + (6,000 - 5,000) × 1.425 = USD 8,175

For example, you purchase an instance of the Insurance mitigation plan, select the Standard function plan, and set the number of domain names that can be protected to 600. The fee for the number of domain names that can be protected per month is calculated based on the following formula:

(10 - 0) × 0 + (500 - 10) × 4.5 + (600 - 500) × 4.1 = USD 2,615

100 < Number of ports ≤ 500
22
500 < Number of ports ≤ 1,500

For example, you purchase an instance of the Insurance mitigation plan and set the number of ports to 80. The fee for the number of ports per month is calculated based on the following formula:
(5 - 0) × 0 + (50 - 5) × 30 +(80 - 50) × 26= USD 2,130

Pay-as-you-go description

After you enable a pay-as-you-go feature, bills are generated only after the usage of the feature meets the bill generation conditions.

Feature	Billing rule	Description
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 can be used to prevent 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

Instance status	Description
Before the instance expires	Alibaba Cloud sends you emails 7 days, 3 days, and 1 day before your instance expires to remind you to renew your subscription.
From the expiration date to 30 calendar days (excluded) after the expiration date	The instance forwards service traffic, and the configurations of the instance are retained. If you renew your instance within this time period, the instance continues to provide protection capabilities based on the specifications that you purchase.
30 calendar days (included) after the expiration date	The instance no longer forwards service traffic and is released. Warning If you no longer require Anti-DDoS Proxy (Outside Chinese Mainland) to protect your service, you must switch service traffic from the Anti-DDoS Proxy (Outside Chinese Mainland) instance to the origin server before 30 calendar days after the expiration date. Otherwise, access to your service may be adversely affected. If you want to switch service traffic, make sure that the domain name of your website does not point to the CNAME assigned by Anti-DDoS Proxy. You must also make sure that your non-website service does not use an exclusive IP address provided by the instance. After all Anti-DDoS Proxy (Outside Chinese Mainland) instances that are created by using your Alibaba Cloud account are released, the configurations that are added to Anti-DDoS Proxy (Outside Chinese Mainland) are permanently deleted. If you want to use Anti-DDoS Proxy (Outside Chinese Mainland) again, you must purchase and configure another Anti-DDoS Proxy (Outside Chinese Mainland) instance.
