Brief introduction
SCDN while (Secure Content Delivery Network), that is, has the CDN service security capabilities, providing a steady acceleration, intelligent predict aggressive behavior, the DDoS attack request to switch to high anti-IP complete cleaning through intelligent scheduling system, and the real user's request access to resources from the normal acceleration nodes. Accelerate the node distributed architecture also have the ability to simultaneously attack the anti-CC, thereby achieving both acceleration and security.
Traditional CDN acceleration service can not withstand large-scale DDoS, CC attack. Anti-alone high IP protection of the source station mode and can not take into account accelerated. But games such as vulnerable, financial, government and enterprise security, electricity providers, such as the medical field must take into account the acceleration of business scenarios, it requires both high penetration ability and has a stable and efficient full-accelerated security CDN link service. Ali cloud resources based on quality SCDN accelerated CDN edge of the cloud Ali, Ali cloud shield deep integration expertise offensive and defensive strategy, can provide one-stop security and acceleration of the overall solution. You can quick start quick access Ali cloud SCDN.

Smart predict attacks and automatically switch to high anti-malicious requests the IP, without human operation, data cleaning, protect the source station. The actual user requests access to resources from the normal acceleration nodes. Intelligent acceleration and security into account:
Features
Anti-DDoS, anti-CC, anti-brush
- DDoS Cleaning: Massive DDoS cleaning ability, can be the perfect defense SYN Flood, ACK Flood, ICMP Flood, UDP Flood, NTP Flood, SSDP Flood, DNS Flood, HTTP Flood
- Anti-attack CC: Accelerated node distributed architecture with the natural ability of anti-CC
- Anti-Brush: CDN malicious users often brush flow leads to economic losses. SCDN nodes frequently accessed by the intelligent recognition abnormal and limit access to unfamiliar IP or the like, to achieve the purpose of preventing the brush
- Smart Scheduling: Algorithms Ali cloud computing flying platform and depth of learning-based, intelligent anticipation DDoS attack, smooth switching high anti-IP, does not affect the online business
- Independent nodes: ordinary simultaneously SCDN node CDN node physical isolation, is constructed entirely separate, secure node acceleration deep integration of security features, the ability to provide high anti one hundred single node G provides a stable and efficient acceleration edge
