Your website anticipates much higher traffic than usual during major events such as new game launching and e-commerce promotions. In this case, you can create scenario policies to apply the Major Events template. This template automatically adjusts anti-DDoS protection policies during major events to prevent blocking normal requests.
Usage notes
Scenario policies are only available for websites that use Enterprise plans.
If you apply a standard DDoS mitigation policy during a major event, normal requests may be blocked. The Major Events template enables the automatic adjustment of anti-DDoS policies based on the following logic:
When a major event begins, the Major Events template takes effect by recording the Global Mitigation Policies settings and the Smart HTTP Flood Protection settings and turning off both switches.
When the major event ends, the template turns on the switches again and restores the Global Mitigation Policies parameter and the Smart HTTP Flood Protection parameter to previous settings.
You can create up to 10 scenario policies in each Alibaba Cloud account.
