Alibaba Cloud provides Anti-DDoS Premium to protect against DDoS attacks for servers deployed outside mainland China.
After you set up an Anti-DDoS Premium instance to protect your services, Anti-DDoS Premium forwards all attack traffic directed toward your servers to a dedicated IP address. Anti-DDoS Premium relies on the state of the art distributed near-origin traffic scrubbing to scrub malicious traffic and forward normal traffic to origin servers. This ensures the stability of your services.
Features
The following table describes the features provided by Anti-DDoS Premium.
Feature | Description |
---|---|
Malformed packet filtering | Anti-DDoS Premium protects your services against attacks, such as frag flood, smurf, stream flood, and land flood attacks, and filters out malformed packets, such as IP packets, TCP packets, and UDP packets. |
Protection against transport-layer DDoS attacks | Anti-DDoS Premium protects your services against attacks, such as SYN flood, ACK flood, UDP flood, ICMP flood, and RST flood. |
Protection against web application DDoS attacks | Anti-DDoS Premium protects your services against HTTP GET flood, HTTP POST flood, and high-frequency attacks. It also supports user-defined rules for access control, such as specific HTTP header field, URIs, and host rules. |
Benefits
- Global near-origin traffic scrubbing
Anti-DDoS Premium uses the anycast mode and the traffic scrubbing centers of Alibaba Cloud around the world to forward DDoS attack traffic to the nearest traffic scrubbing center. It also supports backup and disaster recovery among multiple data centers.
- Unlimited protection
Different from Anti-DDoS Pro, Anti-DDoS Premium relies on global near-source scrubbing to provide unlimited and continuous protection.
Notice If the attacks that target your services impact the infrastructure of anti-DDoS scrubbing centers, Alibaba Cloud reserves the right to throttle the traffic. Traffic throttling on your Anti-DDoS Premium instances may affect your services. For example, user traffic may also be throttled or even routed to a black hole. - Dedicated IP resources
Anti-DDoS Premium provides a dedicated anycast IP address. Each IP address is isolated to avoid any impact on your services caused by DDoS attacks on other customers. This provides you with more secure anti-DDoS services.
- Security reports
Anti-DDoS Premium provides detailed traffic reports and attack prevention reports in real time. This provides you a clear view of your service security.
Scenarios
In this case, the average network latency reaches 300 ms, and intermittent packet loss caused by the congestion of international links may occur. Therefore, we recommend that you deploy servers in mainland China to serve users in mainland China, use Anti-DDoS Pro to protect against DDoS attacks, and comply with relevant China laws and regulations to complete website registration and other compliance procedures.
