After purchasing the CDN service, users will be more concerned about the actual effect in the process of using it. First of all, make sure that it has been activated successfully, and then follow the basic steps to add accelerated domain names and configure CNAME. After all, you can test whether the CDN acceleration is successful. What is the role of CDN accelerated defense in preventing DDOS attacks? Which is more effective for defense than a high defense server or a CDN? Today, let's make a brief comparison.

Recently, many people have a question about high-defense server and CDN defense. Since both can resist DDOS attacks and have defense functions, what's the difference between them? Which is better to use? Today, I will give you a brief analysis of the difference between high defense server and CDN defense. Which is better to use?

High defense server mainly refers to a single hard defense server of more than 50G, which can provide security maintenance for a single customer. Generally speaking, it belongs to a kind of server. According to the environment of each IDC computer room, some provide hard defense and some use soft defense. To put it simply, server types that can help website denial of service attacks, regularly scan existing network master nodes and find possible security vulnerabilities can be defined as high-defense servers.

Defense mode of high-defense server: high-defense server adopts stand-alone defense or cluster defense, and attacks directly on the source server. The attack may cause the bandwidth CPU memory utilization of the server to reach 100%, and may even directly affect the origin server, resulting in problems such as jam, website failure and inaccessibility.

What is the difference between high defense server and CDN defense? Which is better to use?

CDN defense is to add a new network architecture to the existing Internet to publish the content of the website to the "edge" of the network closest to the user, so that users can get the content they need nearby, solve the situation of Internet network congestion and be perplexed by peer DDOS attacks, and improve the response speed of users visiting the website.

Defense method of CDN: CDN adopts multi-node distribution, which can solve the access speed of different network users in different regions, reduce the pressure on the website server, and hide the origin server ip, so that the attacker can not find the origin server ip, can not directly attack the source server, so that the attack hits the CDN node.

Each node of CDN is a stand-alone defense, and each node has a corresponding defense of package defense. Unless the attack exceeds the package defense, the website will not be affected and can provide security for customers' websites.

High-defense server is also a commonly used device for enterprise users, but which one needs to be chosen according to the actual needs of users or CDN defense, the one that suits them is the best.

Both high defense server and CDN defense have their own advantages and disadvantages, and they have different protective functions in different situations. Technically, it comprehensively solves the problem of slow response speed of users visiting websites caused by small network bandwidth, large number of user visits and uneven node diversion.
