The scenario policies allow you to address business peak situations such as new game launches and e-commerce promotions. With Major Event templates, DDoS protection policies are adjusted automatically. This adjustment ensures dynamic adaptation to traffic fluctuations during the designated activity period, reduces false positives for normal users, and maintains continuous business operations during high-concurrency periods.
Before you begin
Scenario policies are only available for websites on Enterprise plans and use best-effort DDoS protection.
If you apply a basic DDoS protection policy during a major event, normal requests may be blocked. The Major Events template enables the automatic adjustment of DDoS protection policies based on the following logic:
When a major event begins, the Major Events template automatically logs the configurations for the HTTP DDoS Attack Protection and Deep Learning and Protection parameters, and then disables these two features.
At the end of the event, the Major Events template restores the configurations of these two features.
You can create up to 10 scenario policies in each Alibaba Cloud account.
