Why is the CDN of Shanghai advanced defense equipment room so expensive? There are two main ways to defend against DDoS attacks: one is to use advanced anti DDoS on the server, and the other is to use advanced anti DDoS on the CDN. Both methods have advantages and disadvantages. Next, we will describe the advantages and disadvantages of advanced anti DDoS servers and advanced anti DDoS CDNs in defending against DDoS attacks. At present, the Royal Anti DDoS Server mainly scans the existing network nodes regularly, configures firewalls at the backbone nodes, discovers possible security vulnerabilities, uses enough machines to resist hacker attacks, and makes full use of network equipment to defend against DDoS attacks. And resist DDoS attacks. However, if the DDoS attack directly attacks the source server, if the defense strategy is improper, the attack will also lead to excessive use of server bandwidth, CPU memory, and even directly affect the source station, resulting in the website being stuck or unable to open access.
CDN is very effective in resisting DDoS attacks, but there are many good and bad CDN providers in the market. Once the user chooses badly, it is likely to bring very bad consequences to the website. In this regard, we must carefully select suppliers. The above is a small version, which introduces two DDoS defense modes of the server. The specific defense mode is also selected according to the actual situation of the user site. We can even try BGP ECS Advanced Anti DDoS CDN. As a professional security platform, even if the advanced defense Royal CDN is combined with AI neural network, the defense effect against DDoS attacks and CC attacks is stronger.
Advantages of advanced anti DDoS CDN products:
1. Rich resources. There are more than 160 excellent computer rooms and more than 300 CDN nodes in China, covering telecom, China Unicom, China Mobile, China Railcom, education network, telecom, long line, cable and technology network operators. More than 60 overseas nodes, covering Asia Pacific, North America, Europe, South America and Africa.
2. Global load balancing, regional access scheduling strategy and intelligent energy distribution of health nodes [server, advanced defense, North Korea] to ensure the latest access of end users. During the health check, all nodes of the whole network will automatically switch to [Korean website server] within 20 seconds.
3. Full content cloud distribution enables direct private transmission over private networks and optimal physical links. Optimize the transmission protocol: E-TCP. Intelligent analysis, dynamic and static separation, ensure content security and effective access.
Advanced anti DDoS CDN product functions:
1. Accelerate, add, delete, change, and check one-stop solutions through flexible deployment, quick opening, and self-service of the management interface CDN, and reduce your management costs.
2. The self-developed scheduling algorithm subverts the traditional central scheduling system architecture. Through the self-developed intelligent scheduling algorithm, traffic distribution between servers in different regions of the WAN can be realized, and the best server service of the nearest user can be used to ensure the quality of access to the Internet.
3. Anti theft chain to prevent resources from being maliciously referenced. By customizing the reference white list, you can limit the URL resources of the website, prevent chain theft, and save your unnecessary expenses.
4. Multi scenario business support can meet the needs of portal information, multimedia video, games or mobile applications with different resource types. CDN will intelligently allocate scheduling domains to provide business support for your website and accelerate demand.
