Anti-DDoS:Cloud service specifications and scrubbing thresholds

Last Updated:Jul 19, 2024

When the network traffic destined for a cloud service that is assigned a public IP address exceeds the specified traffic scrubbing threshold, Anti-DDoS Basic automatically scrubs the traffic to protect your business from DDoS attacks.

For more information about traffic scrubbing, see Terms.

The traffic scrubbing threshold supported by each cloud service varies based on the instance specification of the cloud service. When you create or change the specifications of an Elastic Compute Service (ECS) instance, Server Load Balancer (SLB) instance, or NAT gateway, the system automatically calculates the traffic scrubbing threshold based on the current instance specification.

Note

The system calculates blackhole filtering thresholds for instances of each cloud service based on the regions in which the instances reside and the bandwidth of the instances.
