After purchasing the CDN service, users will be more concerned about the actual effect in the process of using it. First of all, you need to make sure that it has been activated successfully, and then follow the basic steps to add accelerated domain names and configure CNAME. After all these have been successfully completed, CDN can be used normally. Many users have a question, which is often asked, which is the difference between high defense server and CDN defense and which is better.

Recently, many people have questions about high defense servers and CDN defenses. Now that they can resist DDOS attacks and have defense capabilities, what's the difference between them? Which is better to use? Today, I will briefly analyze the difference between high defense server and CDN defense. Which is better?

A high defense server mainly refers to a single server with a single hard defense of 50G or more. It can provide security maintenance for a single customer. Generally speaking, it belongs to the server. Depending on the environment of each IDC room, some provide hard defense and use. Soft defense. In short, a server type that can assist in a denial of service attack on a website and periodically scan the existing network master node for possible security vulnerabilities can be defined as a high defense server.

High defense server defense mode: high defense server uses stand-alone defense or cluster defense to directly attack the source server. The attack may cause the server bandwidth CPU memory utilization to reach 100%, and may even directly affect the origin server, resulting in problems such as being stuck or the website cannot be opened.

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

CDN defense is to add a new network architecture to the existing Internet and publish the content of the site to the "edge" of the network closest to the user, so that users can get the content they need nearby and solve the congestion problem of Internet. The Internet. Being plagued by peer DDOS attacks improves the response speed of users who visit the website.

CDN defense method: CDN adopts multi-node distribution, which can solve the access speed of different network users in different regions, solve the problem of concurrently reducing the pressure on the website server, hide the origin server ip, so that the attacker can not find the origin server ip and can not attack directly. Go to the source server and make the attack hit the CDN node.

Each node of the CDN is an independent defense. Each node has a corresponding defense against packet defense. Unless the attack exceeds the package defense, the site will not be affected and can protect the customer's website.

High defense servers are also commonly used by enterprise users, but they need to be selected according to the actual situation of users and CDN defense. What suits you is the best.

Both high defense server and CDN defense have their own advantages and disadvantages. They have different protection functions in different situations, which comprehensively solve the problems of small network bandwidth, large number of user visits and uneven distribution of nodes leading to users visiting the website. The problem of slow speed.
