Alibaba Cloud Anti-DDoS Pro is a value-added, paid service that safeguards network servers under high volume DDoS attacks. Featuring a set of high-defensive IPs, the Anti-DDoS Pro acts as a protective barrier for the origin.
Through configuring the high defensive IPs and rerouting traffic to them, all requests are cleaned, before being forwarded to the origin. With malicious traffic blocked, the origin gained higher availability and stability. Additionally, after enabled the Anti-DDoS Pro service, the traffic traction and re-injection are not necessary during a DDoS attack.
The Anti-DDoS Pro supports a peak protection bandwidth of 20Gbps ~ 300Gbps on servers inside and outside Alibaba Cloud. For cost-effective reasons, flexible payment plans are available that service fees are incurred based on the daily attack volumes.
