Alibaba Cloud Anti-DDoS Basic is enabled and initialized by default with the creation of ECS, Server Load Balance, or EIP instances. This service provides a 5 Gbps mitigation capacity free of charge. The cleaning threshold value can be configured in accordance with specific business requirements.


Follow these steps to configure the cleaning threshold value that meets your business requirements:

  1. Log on to the Alibaba Cloud console.

  2. Click Anti-DDoS Basic under Security.

  3. On the displayed Anti-DDoS Basic page, select View details under the instance to be configured in the Operation column.


  4. Check the current Cleaning trigger settings, and click Advanced anti-DDoS settings to configure advanced settings to match your business needs.


  5. In the dialog box, configure the Cleaning threshold value setting.


    • For Automatic setting, the system dynamically adjusts the cleaning threshold value based on ECS’s traffic load.

    • For Manual setting, you must select the request amount restriction, such as traffic and packets per second.

  6. Click OK to complete the action. The updated settings are applied with the latest settings.
