Content Delivery Network (CDN) is a distributed network composed of edge node server clusters distributed in different regions and built and covered on the bearer network. CDN shares the pressure of origin sites, avoids network congestion, ensures accelerated distribution of website content in different regions and scenarios, and improves resource access speed. Many users will encounter DDOS attacks in the actual use of CDN. Today, Xiaobian introduces two mainstream methods to defend against DDOS attacks:

There are two main ways to protect against DDoS attacks: one is to use a high-defense server, and the other is to use a high-defense CDN. Both methods have advantages and disadvantages. Next, we'll detail the pros and cons of high-defense servers and high-defense CDNs when it comes to defending against DDoS attacks.

At present, high-defense servers mainly scan existing network nodes periodically, configure firewalls in backbone nodes, discover possible security vulnerabilities, use enough machines to resist hacker attacks, and make full use of network equipment to defend against DDoS attacks. Defend against DDoS attacks. However, DDoS attacks directly attack the origin server. If the defense strategy is improper, the attack will also cause the server bandwidth CPU memory usage to be too high, and even directly affect the origin station, resulting in problems such as jamming or website failure to open and access.

CDNs are very effective at defending against DDoS attacks, but there are many good and bad CDN providers on the market. Once the user's choice is bad, it is likely to lead to very bad consequences for the website. In this regard, we must carefully select suppliers. The above is a small version that introduces you to two server defense DDoS modes. The specific defense mode is also selected according to the actual situation of the user site.

Xiaobian suggests that we can even try a BGP Cloud Virtual Machine + high-defense CDN. As a professional security platform, even if the combination of high-defense CDN and AI neural network has stronger defense effect for DDoS attack and CC attack.

High defense CDN product advantages:

1. Rich in resources, there are more than 160 excellent computer rooms in China and more than 300 CDN nodes, covering telecom, Unicom, mobile, Tietong, education network, telecom, long-term, cable and science and technology network operators. More than 60 overseas nodes covering Asia Pacific, North America, Europe, South America and Africa.

2. Global Load Balancer, Regional Access Scheduling Policy, Intelligent Allocation of Healthy Nodes to Ensure Proximity of End User Access. During a health check, all nodes in the entire network automatically switch within 20 seconds.

3. Full content cloud distribution, direct private transmission of Private Cloud, optimal physical link. Optimized transmission protocol: E-TCP. Intelligent analytics, dynamic and static separation to ensure content security and effective access.

CDN Product Features:

① Flexible deployment, fast opening, self-service through the management interface CDN acceleration, add, delete, change, check one-stop solution, reduce your management costs.

② The scheduling algorithm independently developed subverts the traditional central scheduling system architecture. Through self-developed intelligent scheduling algorithms, traffic distribution between servers in different areas of the WAN is realized to ensure the use of the best server service from its nearest users, thus ensuring the quality of access to the Internet.

③ Anti-theft chain, prevent resources from being maliciously referenced Through the custom reference white list, you can limit the website's URL resources, prevent theft chain, and save you unnecessary expenses.

④ Multi-scenario service support, portal information, multimedia video and audio, games or mobile application APP that meet your different resource types distribution needs. CDN will intelligently allocate scheduling domains to provide service support for your website and accelerate demand.
