Prerequisites

Purchasing an Anti-DDoS Pro instance

Anti-DDoS Pro (Standard)

1. Go to the Anti-DDoS Pro buy page and select the Standard package.

2. Configure the following parameters as needed:
Parameter
Description
Line
Provide the BGP line and non-BGP line (CTCC, CUCC, CMCC).
Specifications
Access mode: Quick access
Bandwidth type: Tencent Cloud multi-BGP line network
Protection capacity: All-out protection
Protection scope: Public IPs of Tencent Cloud resources, including CVM, CLB, GAAP, WAF, and so on
Region
Select the region of the public IP of the Tencent Cloud resource. Currently, Anti-DDoS Pro can only provide DDoS protection for Tencent Cloud public IPs in the same region.
Protected IPs
Set the number of public IPs to be protected by the Anti-DDoS Pro instance. Available specifications: 10 IPs (default), 50 IPs, and 100 IPs.
Bandwidth
Normal bandwidth of your service. It is billed based on the monthly 95th percentile of either the incoming or outgoing traffic (whichever is higher).
Validity period
Select for how long you want to purchase the instance. The fees are prepaid and calculated based on the base protection bandwidth, business bandwidth, and validity period.
Protection quota
Refer to the number of times of all-out protection available for your business.
(Optional) Auto-renewal
Automatically renew your subscription upon expiration if your Tencent Cloud account has sufficient balance. The renewal cycle is three months for quarterly and yearly subscriptions.
Note:
You can upgrade or enable elastic business bandwidth when the business bandwidth is insufficient or a higher QPS is needed. After elastic business bandwidth is enabled, you will be charged for the amount of bandwidth beyond the specified amount. For billing details, see Billing Overview (Standard). Please select a specification after reasonably assessing your business bandwidth.
Anti-DDoS Pro allows you to exceed your plan's limit, but all-out protection will become unavailable and only base protection remains when the limit is exceeded for a total of 36 hours in a month.
3. Click Pay Now to complete your purchase.

Anti-DDoS Pro (Enterprise)

1. Go to the Anti-DDoS Pro buy page and select the Enterprise package.

2. Configure the following parameters as needed:
Parameter
Description
Specifications
Access mode: Quick access
Bandwidth type: Tencent Cloud multi-BGP line network
‌Protection scope: Tencent Cloud Anti-DDoS EIPs
Note:
Chinese mainland: The protection capability adopts the "base protection + elastic protection" mode.
Outside the Chinese mainland: Tencent Cloud Anti-DDoS cleansing center provides all-out protection.
Region
Select the region of the public IP of the Tencent Cloud resource. Currently, Anti-DDoS Pro can only provide DDoS protection for Tencent Cloud public IPs in the same region.
Protected IPs
Set the number of public IPs to be protected by the Anti-DDoS Pro instance. Available specifications: 10 IPs (default), 50 IPs, and 100 IPs.
Base protection bandwidth
Support prepaid monthly subscription. We recommend you select a base protection bandwidth slightly higher than the average value of historical attack traffic, which will allow you to handle normal attacks.
Elastic protection bandwidth
Billed based on the actual protection bandwidth by day. We recommend you select an elastic protection bandwidth slightly higher than the largest attack traffic in history to defend against surges in attack traffic, reducing the possibility of IP blocking caused by traffic exceeding the protection bandwidth limit.
Bandwidth
Normal bandwidth of your service. It is billed based on the monthly 95th percentile of either the incoming or outgoing traffic (whichever is higher).
Validity period
Select for how long you want to purchase the instance. The fees are prepaid and calculated based on the base protection bandwidth, business bandwidth, and validity period.
Protection quota
Refer to the number of times of all-out protection available for your business.

Purchasing an Anti-DDoS Advanced instance

Anti-DDoS Advanced (Chinese Mainland)

1. Go to the Anti-DDoS buy page and click **Anti-DDoS Advanced (Chinese Mainland)**.
2. Configure the following parameters as needed.

Line: Provide the BGP line and non-BGP line (CTCC, CUCC, CMCC).
Specifications:
Access mode: Proxy
Resources: 1 dedicated IP
Bandwidth type: multi-line BGP
Protection capability: Base + Elastic
Base protection bandwidth: Support prepaid monthly subscription. We recommend you select a base protection bandwidth slightly higher than the average value of historical attack traffic, which will allow you to handle normal attacks.
Elastic protection bandwidth: Billed based on the actual elastic protection bandwidth by day. We recommend you select an elastic protection bandwidth slightly higher than the largest attack traffic in history minus the base protection bandwidth to defend against surges in attack traffic, avoiding IP blocking caused by traffic exceeding the protection bandwidth limit.
Note:
Billable elastic bandwidth = Peak attack bandwidth – Base protection bandwidth
Business bandwidth: Apply to both the incoming Anti-DDoS forwarding traffic and the outgoing Anti-DDoS traffic. Business bandwidth needs to be higher than the peak bandwidth of the two, whichever is greater.
Note:
You can upgrade or enable elastic business bandwidth when the business bandwidth is insufficient or a higher QPS is needed. After elastic business bandwidth is enabled, you will be charged at 1 USD/Mbps/day for the amount of bandwidth exceeding the specified amount. Please select a specification after reasonably assessing your business bandwidth.
Forwarding rules: Refer to the total number of TCP/UDP ports (for non-website connections) and HTTP/HTTPS domain names (for website connections) that you can configure for an Anti-DDoS Advanced instance.
Validity period: Select for how long you want to purchase the instance. The fees are prepaid and calculated based on the base protection bandwidth, business bandwidth, and validity period.
(Optional) Auto-renewal: Automatically renew your subscription upon expiration if your Tencent Cloud account has sufficient balance. The renewal cycle is three months for quarterly and yearly subscriptions.

Base protection bandwidth: Support prepaid monthly subscription. We recommend you select a base protection bandwidth slightly higher than the average value of historical attack traffic, which will allow you to handle normal attacks.
Elastic protection bandwidth: Billed based on the actual protection bandwidth by day. We recommend you select an elastic protection bandwidth slightly higher than the largest attack traffic in history to defend against surges in attack traffic, avoiding IP blocking caused by traffic exceeding the protection bandwidth limit.
Business bandwidth: Apply to both the incoming Anti-DDoS forwarding traffic and the outgoing Anti-DDoS traffic. Business bandwidth needs to be higher than the peak bandwidth of the two, whichever is greater.
