This topic describes how to associate IP addresses of multiple cloud resources to
one Anti-DDoS Pro or Anti-DDoS Premium instance in cloud service interaction and tiered
protection scenarios. If one of the cloud resources is attacked, service traffic of
this cloud resource is switched to Anti-DDoS Pro or Anti-DDoS Premium.
Cloud service interaction
- Configure Sec-Traffic Manager.
For example, you have three cloud resources. Add an interaction rule for the IP address
of each resource and associate the three rules with the IP address of the Anti-DDoS
Pro or Anti-DDoS Premium instance. For more information, see
Create a cloud service interaction rule.
- Modify the DNS records.
- Verify the DNS records. Open a DNS test website to verify that the CNAME records added
in Step 2 take effect.
Tiered protection
- Purchase an Anti-DDoS Origin Enterprise instance.
Add the three cloud resources to Anti-DDoS Origin Enterprise for protection. For more
information, see
Add a protection target.
- Configure Sec-Traffic Manager.
Create a tiered protection rule for the IP address of each cloud resource and associate
the three rules with the IP address of the Anti-DDoS Pro or Anti-DDoS Premium instance.
