Alibaba Cloud Anti-DDoS Pro is a paid service that features a set of high-defensive IPs, and acts as a protective barrier for the origin. It safeguards network servers under high volume DDoS attacks.
After configuring the high defensive IPs for the network servers, all traffic passes through the Anti-DDoS Pro instance before rerouting to the origin. Anti-DDoS Pro service cleans all traffic, mitigates DDoS attacks, and then forward traffic to the origin. With malicious traffic mitigated, the origin gains higher availability and stability.
Additionally, after enabling the Anti-DDoS Pro service, the traffic traction and re-injection are not necessary when your origin suffers DDoS attacks.
The Anti-DDoS Pro supports a peak protection bandwidth of 20Gbps ~ 600Gbps on servers inside and outside Alibaba Cloud. To make it more cost-effective, you are offered various flexible payment plans. Wherein, the fees are incurred according to the daily attack volumes.
