Guangzhou CDN defense and advanced defense server? Which is better, CDN defense is a common security measure for enterprises to protect servers, so someone asked what is the difference between CDN defense and advanced defense servers, which is better? Today, Wei will introduce the differences between them. CDN is a kind of website acceleration, which can solve the problem of slow website opening caused by the low load capacity and bandwidth of server A website. The server performance is relatively poor, the load capacity is limited, and the advantages are submerged by sudden traffic, which directly leads to server crash and website failure. Advanced anti DDoS server mainly refers to an independent single hard defense server with 50G or more, which can provide security maintenance for a single customer. Generally speaking, it belongs to the server. It provides hard defense or soft defense according to the IDC room environment.
CDN defense is to add a new network architecture to the existing Internet, 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 Internet congestion and be troubled by peer-to-peer DDOS attacks [UK independent server], and improve the response speed of users when visiting the website. Technically, it comprehensively solves the problem of slow response speed caused by small network bandwidth, large user visits, and uneven node distribution. In short, it is the server type, which can help websites attack denial of service, regularly scan the existing network master node, and find possible security vulnerabilities. It can be defined as advanced anti DDoS server
Advanced anti DDoS server defense mode. Advanced anti DDoS server adopts stand-alone defense or cluster defense. The attack that directly hits the source server may lead to 100% utilization of server bandwidth CPU memory, or even directly affect the source station, causing interference, website opening, access and other problems. CDN defense mode. CDN adopts multi node distribution, which can solve the access speed of different network users in different regions, reduce the pressure of website servers, hide the source station IP, so that attackers can not find the source station IP, and can not directly attack the source server, so that attacks can reach the CDN nodes.
Each node of the CDN is a stand-alone defense, and each node has a corresponding packet defense defense. Unless the attack exceeds the package defense, the website will not be affected and can provide security for the customer's website. What is the difference between CDN and advanced anti DDoS, the server? The CDN is adjusted according to the service type and attack problem, and the advanced defense server is the default defense mechanism. Advanced anti DDoS server is also a common device for enterprise users, but which one CDN defense needs should be selected according to the actual situation of users, just the one that is suitable for you.
Guangzhou CDN defense and advanced defense server? Which one is better, how to choose advanced anti DDoS virtual machine? It is understood that the application of servers is indispensable to the creation of websites, which comes from the consideration of website security. Many companies that choose Hong Kong ECS will consider whether to choose advanced anti DDoS servers when planning new stations. The server, advanced defense, is the key to show the website's higher defense. In terms of server defense against 10G, 20G, 100G or higher ddos attacks, especially for frequently attacked websites, advanced defense virtual machine is more reasonable than gender servers in terms of security.
1. Reliability
The first is to ensure that all websites can work normally within 7 * 24 hours. The second is that the hardware configuration and mobile phone software have complete defenses to reflect deliberate attacks in the least time.
2. System configuration
For example, CPU, running memory, hard disk size, maximum network bandwidth, etc. Generally, cloud service providers display default settings. If they don't, they can choose the default settings. Then, consider whether to upgrade in the middle and later stages according to the resource occupation of advanced anti DDoS and servers.
3. Scale of national defense force
You can refer to the IT operation and maintenance management cost and hacker attack status to determine the highest value of advanced anti DDoS virtual machine, and select a host room that can improve its defense as much as possible.
4. Website opening speed
In addition, the website opening speed of the advanced anti DDoS virtual machine [host decompression] is also a key factor. Before renting advanced anti DDoS servers, you should check the server speed or network speed. After all, the basic role of the server should be guaranteed.
5. Select a reliable IDC service provider
Finally, we suggest that you choose a reliable IDC service provider as far as possible, so that when after-sales service problems occur, there will be technical professionals on the 7 * 24 line to improve the efficiency of problem inspection and handling.
