Content distribution network (Content Delivery Network, referred to as CDN) is a distributed network, which is established and covered on the bearer network, which is composed of edge nodes and cloud servers distributed in different areas. CDN shares the pressure on the origin server, avoids network congestion, ensures that the distribution of website content is accelerated in different regions and different scenarios, and improves the speed of resource access. Today, I would like to introduce to you whether we should choose high defense CVM or high defense cdn when we encounter DDOS attacks.

In the IDC industry, high defense ip, high defense cdn, high defense second unblocking, high defense cdn, high defense CVM and so on, all of these can be used to defend against various network attacks. Tengyou editor introduced high defense ip and high defense cdn before, and today we will introduce the choice of high defense CVM or high defense cdn for DDOS attack.

High-defense CDN defense attack mode

High-defense CDN defense method is through the use of enough CDN nodes and a single CDN node to achieve DDoS protection, with a certain DDoS protection capability. In general, high-defense CDN Tengyou has more than 50 CDN nodes, while a single CDN node has DDoS protection between 20 and 100 Gbps.

Choose high defense CVM or high defense cdn for DDOS attack

High defense server defense attack form:

1. Ddos traffic cleaning and application layer protection

Some high-defense servers can provide high-bandwidth, accurate and reliable DDoS traffic cleaning functions, which can effectively protect against all kinds of ddos attacks, application layer attacks and so on. Traffic cleaning cluster can achieve accurate flow cleaning function and support CC protection.

2. Display of attack statistics and defense reports

Many merchants can provide DDoS traffic cleaning statistics, provide reports showing real-time and historical attacks, and provide security event display. Provide statistical information and traffic monitoring reports.

3. Upgrade protection of elastic bandwidth

On the basis of the original guaranteed bandwidth, flexible bandwidth upgrade is provided to enhance protection, and users can flexibly choose the range of bandwidth. Generally speaking, the larger the bandwidth, the better the protection against heavy traffic attacks. Ddos high-defense server leasing can resist all kinds of DDoS attacks in network layer and application layer.

The difference between High Defense Server and High Defense cdn

High defense CDN makes corresponding adjustments according to business types and attack problems, while high defense server is the default defense mechanism.

The high defense server adopts stand-alone defense or cluster defense, and the attack is directly hit on the source server. If the high defense server can't handle it, it's dead! High-defense CDN is different, high-defense CDN can disperse these attacks to each node, reducing the pressure of DDOS attacks to a low value.

High defense CDN can allocate multiple high defense nodes, which has a significant effect, and high defense CDN can hide the source server IP and improve the response speed of the website. 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.

DDOS attack to choose high-defense server or high-defense cdn, in defense of DDOS attacks, choose high-defense server or high-defense cdn both have advantages. Which is good to withstand the network attack is the final say, the specific choice of which way depends on the site is often subject to network attacks to decide.
