After you purchase an on-demand Anti-DDoS Origin instance, you can configure the start mode for the instance. If you use the default start mode and DDoS attacks are detected on your server in a data center, you must manually enable traffic rerouting to the instance. You can also enable the Automatic (NetFlow) mode. If the inbound bandwidth or packets consecutively exceed a threshold for the specified number of times, the Automatic (NetFlow) mode allows the system to automatically reroute traffic to the instance.
Prerequisites
- An on-demand Anti-DDoS Origin instance is purchased.
Note On-demand instances protect servers in on-premises data centers outside mainland China and cloud assets based on Classless Inter-Domain Routing (CIDR) blocks. You must contact sales personnel to purchase on-demand instances.
- To protect the assets that are not deployed on Alibaba Cloud, such as servers in data centers, you must provide the NetFlow information of these servers for Alibaba Cloud. For more information, submit a ticket or use a DingTalk group to submit the application.
