Alibaba Cloud servers enjoy a free DDoS mitigation capacity by default. When they are targeted by traffic attacks, the traffic scrubbing service is activated automatically. The traffic scrubbing service consists of three units: detecting center, cleaning center, and centralized management center.
The detecting center monitors data traffic flowing into the cloud server, and identifies abnormal traffic in a timely manner, such as DDoS attack. When an abnormity is detected, the management center guides the scrubbing center to clean suspicious traffic based on the traffic diversion policy. Malicious traffic is removed, while legitimate traffic is returned to the original instance. This ensures only legitimate traffic can be forwarded to the target system.
