1,000 Gbps	91,853	918,533
1,500 Gbps	135,078	1,339,977

Premium Edition

Only a basic protection bandwidth of 5 Gbps is supported. The basic instance fee is USD 2,880/month.

The basic instance fee covers the default minimum specifications listed in the following table. You can extend these specifications as needed.

Configuration item	Professional Edition Instance Type Values	Premium Edition value	Billing method	Description
Burstable protection bandwidth	30 Gbps	Not supported	Pay-as-you-go	Pay-as-you-go fees apply when attack traffic exceeds the basic protection bandwidth but stays below the burstable protection bandwidth.
Clean bandwidth	100 Mbps	100 Mbps	Subscription	Maximum clean traffic throughput under normal conditions. Can be extended.
95th percentile burstable clean bandwidth	Daily 95th percentile	Daily 95th percentile	Pay-as-you-go	Enables daily 95th percentile billing for clean bandwidth. Pay-as-you-go fees apply when actual bandwidth exceeds the clean bandwidth but stays below the 95th percentile burstable clean bandwidth threshold.
Clean queries per second (QPS)	3,000	3,000	Subscription	Maximum concurrent HTTP/HTTPS requests under normal conditions. Can be extended. Note Set this parameter based on your actual service usage. If your actual usage exceeds the Clean QPS specification you selected at purchase, packet loss may occur and full logs may be incomplete.
95th percentile burstable QPS	Daily 95th percentile	Daily 95th percentile	Pay-as-you-go	Enables daily 95th percentile billing for Clean QPS. Pay-as-you-go fees apply when actual QPS exceeds the Clean QPS but stays below the 95th percentile burstable QPS threshold.
Function plan	Standard Plan	Standard Plan	Subscription	Includes Standard and Enhanced function plans. The Enhanced plan improves service access and DDoS attack mitigation capabilities. For more information, see Differences between Standard and Enhanced function plans.
Number of protected domain names	50	50	Subscription	Number of HTTP/HTTPS domains that can be protected. Can be extended. Every 10 additional domain names allow one additional first-level domain. For example, with 50 domain names, the total number of first-level domains cannot exceed 5.
Number of ports	50	50	Subscription	The number of TCP and UDP ports supported by the instance, which can be increased using an extension.

Fees for extendable configuration items

Clean bandwidth

Clean bandwidth (Mbps)	Unit price (USD/month/Mbps)
0 < Clean bandwidth ≤ 100	0
100 < Clean bandwidth ≤ 600	15
600 < Clean bandwidth ≤ 200,000	11

For example, if you select 500 Mbps for Clean Bandwidth when purchasing an instance, you pay the following monthly fee for the extended clean bandwidth:

(100 - 0) × 0 + (500 - 100) × 15 = USD 6,000

Clean queries per second (QPS)

Clean QPS	Unit price (USD/month/QPS)
0 < QPS ≤ 3,000	0
3,000 < QPS ≤ 5,000	1.5
5,000 < QPS ≤ 8,000	1.425
8,000 < QPS ≤ 10,000	1.35
10,000 < QPS ≤ 50,000	1.275
50,000 < QPS ≤ 100,000	1.05
100,000 < QPS ≤ 300,000	0.9

For example, if you select 6,000 business QPS when you purchase an instance, you are charged monthly for the extended instance's business QPS.

(3,000 - 0) × 0 + (5,000 - 3,000) × 1.5 + (6,000 - 5,000) × 1.425 = USD 4,425

Function Plan

Enhanced function plan: USD 1,200/month

Number of protected domain names

Number of domain names	Unit price for Standard function plan (USD/month/domain)	Unit price for Enhanced function plan (USD/month/domain)
0 < Number of domain names ≤ 50	0	0
50 < Number of domain names ≤ 200	4.5	7.5
200 < Number of domain names ≤ 600	4.2	7
600 < Number of domain names ≤ 2,000	3.9	6.5
2,000 < Number of domain names ≤ 20,000	2.7	4.5

For example, if you select the Standard function plan and set the number of protected domain names to 600 when purchasing an instance, you pay the following monthly fee for the additional domain names:

(50 - 0) × 0 + (200 - 50) × 4.5 + (600 - 200) × 4.2 = USD 2,355

Number of ports

Number of ports	Unit price (USD/month/port)
0 < Number of ports ≤ 50	0
50 < Number of ports ≤ 150	7.5
150 < Number of ports ≤ 400	6.75
400 < Number of ports ≤ 1,000	6
1,000 < Number of ports ≤ 1,500	4.5

For example, if you set the number of ports to 200 when purchasing an instance, you pay the following monthly fee for the additional ports:

(50 - 0) × 0 + (150 - 50) × 7.50 + (200 - 150) × 6.75 = USD 1,087.5

Part II: pay-as-you-go

You can enable these features as needed. You are charged only when usage thresholds are exceeded.

Feature	Billing method	Description
Burstable protection bandwidth	Pay-as-you-go (daily)	Available only for Professional Edition instances. Provides additional DDoS mitigation capacity beyond the basic protection bandwidth. For more information, see Billing of burstable protection bandwidth.
Burstable clean bandwidth	Pay-as-you-go (daily or monthly)	Provides additional clean bandwidth during normal traffic spikes to prevent service throttling. For more information, see Billing of the burstable clean bandwidth feature.
Burstable QPS	Pay-as-you-go (daily or monthly)	Provides additional Clean QPS capacity during traffic surges to prevent service throttling. For more information, see Billing of the burstable QPS feature.

Expiration policy

Time period	Service traffic forwarding	Instance configuration
0–6 days after expiration	Retains a 5 Gbps blackhole threshold. Traffic exceeding 5 Gbps triggers blackhole filtering.	Configuration retained.
7–14 days after expiration	Service traffic forwarding stops. Resumes after renewal. Warning To avoid service disruption, switch traffic to your origin server at least 7 days before expiration. • Website services: Ensure domain name resolution does not point to the Anti-DDoS Proxy CNAME address. • Non-website services: Ensure your service IP does not use the Anti-DDoS Proxy exclusive IP address.	Configuration retained.
Day 15 after expiration	Service traffic forwarding stops.	Instance released. Warning After all Anti-DDoS Proxy instances under your account are released for 30 days, the system automatically clears all associated domain and port forwarding rules. The 30-day countdown starts from the release of the last instance.

Note: Expiration notifications and release notifications are temporarily unavailable. Starting seven, three, and one day before your instance expires, Alibaba Cloud sends reminders via and email to notify you that your instance is about to expire and prompt you to renew.
