What this article shares with you is about the difference between high-defense server and high-defense CDN. The editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article. Let's take a look at it with the editor.

High Defense CDN:

That is, content diversion network traffic defense, the principle is to build a content distribution network on the network, relying on the edge servers deployed in various places, through the load balancing, content distribution, scheduling and other functional modules of the central platform, so that users can get the content they need nearby without directly visiting the source server of the website. Its principle is simply to set up multiple high-defense CDN nodes, when there is a CDN node attack, all nodes bear. The site will not be inaccessible because a node is killed by an attack, and the source IP of the site can be hidden.

High defense server:

The high defense server adopts stand-alone defense or cluster defense, and the attack is directly hit on the source server. The high-defense server mainly protects against DDoS attacks by regularly scanning existing network nodes, configuring firewalls in backbone nodes, finding possible security vulnerabilities, using enough machines to withstand hacker attacks, making full use of network equipment to protect network resources, and filtering unnecessary services and ports. To really do a good job in high defense, it is obviously not enough to rely on hard defense alone. Strong computer rooms will make strategies on hard defense to deal with different kinds of attacks. If the defense strategy is not in place, the attack will still lead to excessive bandwidth, CPU and memory utilization of the server, which will directly affect the origin server and cause service interruption and other problems.

The difference between High Defense CDN and High Defense Server

High defense CDN is adjusted according to business type and attack problem, and high defense server is the default defense mechanism.

High defense servers use stand-alone defense or cluster defense to attack directly on the source server, while high defense CDN can disperse these attacks to each node, reducing the pressure of DDOS attacks to a low value.

The high defense server is protected by deploying a hardware firewall in the computer room through simple traction, and the traffic is concentrated in one node; the high defense CDN can allocate multiple high defense nodes, which has a significant defense effect, and the high defense CDN can hide the source server IP and improve the response speed of the website.

Do you choose high defense server or high defense CDN for DDoS attack?

The high-defense server uses traffic traction technology to defend, which can distinguish normal traffic from attack traffic, pull the traffic with attacks to the devices that can defend against DDOS, CC and other attacks, and pull the direction of traffic attacks to other devices instead of choosing to resist them.

CDN adopts multi-node distributed defense, 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, and make the attack hit the CDN node.

Both of them are the mainstream products of DDoS attack defense, and both have their own advantages, and they can prevent DDoS attacks to a certain extent, but they also have their own shortcomings. The enterprise chooses which defense method should also be chosen according to the actual attack on its website.

What is the difference between high-defense server and high-defense CDN? The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
