Advanced mitigation feature of Anti-DDoS Premium
Integrating all mitigation capacities of Alibaba Cloud Anti-DDoS scrubbing centers around the world, Anti-DDoS Premium defends against DDoS attacks to secure your workloads.
Statistics show that workloads protected by Anti-DDoS Premium are less likely to be attacked. Typically, attackers launch DDoS attacks to cause financial loss to the target workloads. Due to the cost of launching DDoS attacks, repeated failures will cause the attackers to stop. The advanced mitigation feature of Anti-DDoS Premium provides unlimited mitigation capacities and can integrate all mitigation capacities of Alibaba Cloud Anti-DDoS scrubbing centers around the world to secure your workloads.
Plans of Anti-DDoS Premium
- Insurance Plan
Each month, Anti-DDoS Premium Insurance Plan offers two free advanced mitigation sessions, featuring unlimited mitigation capabilities. When your workloads receive HTTP flood attacks, Anti-DDoS Premium provides unlimited mitigation capacities to protect your workloads within the following 24 hours. This consumes one mitigation session. The number of advanced mitigation sessions is reset to two at the beginning of every month during the service period.Note To purchase more advanced mitigation sessions, see Global advanced mitigation.For example, a protected IP address suffers DDoS attacks at 11:20:00 (UTC+8), September 12, and an advanced mitigation session is triggered. Within 24 hours, Anti-DDoS Premium provides unlimited mitigation capacities for this IP address. The protected IP address suffers another DDoS attack at 18:50:00 (UTC+8), September 13, and an advanced mitigation session is triggered again. After 24 hours, the advanced mitigation stops and the two advanced mitigation sessions of the Anti-DDoS Premium Insurance plan in September are exhausted. The advanced mitigation sessions are automatically reset to two at the beginning of the following month, which is October 1.
Insurance Plan is a basic solution of Anti-DDoS Premium and applies to users who are less vulnerable to attacks.
- Unlimited Plan
Anti-DDoS Premium Unlimited Plan provides unlimited advanced mitigation capabilities for your workloads. After you purchase the Unlimited plan, Anti-DDoS Premium provides an unlimited number of mitigation sessions to protect your workloads against DDoS attacks.

Subscription-based Anti-DDoS Premium instances do not support refunding. After you start using a subscription-based Anti-DDoS Premium instance, you cannot cancel the subscription.
Assume that you need to connect the workloads of three websites to an Anti-DDoS Premium instance, the normal outbound traffic peak of each website does not exceed 50 Mbit/s, and the total workload traffic does not exceed 150 Mbit/s. In this case, you only need to make sure that the maximum bandwidth of the purchased instance is higher than 150 Mbit/s.
Choose a domain protection specification
For every 10 additional protected domain names, the total number of supported top-level domains is increased by one. By default, an Anti-DDoS Pro instance supports a maximum of 10 domain names. In this case, only one top-level domain is supported.
For example, you add the top-level domain
abc.com to the instance, and then add 9 subdomains or wildcard domains, such as
abc.com, consume the quota.
abc.comor its subdomains to an Anti-Premium instance, and try to add another top-level domain
xyz.comor its subdomains, the following message appears:
The quota of top-level domains has been exceeded. Upgrade the instance to increase the quota.
In this case, you must upgrade the instance to support an additional 10 domains.
