Which is more suitable to be an advanced anti DDoS server, cloud server or physical machine

ECS can be said to be the most popular and accessible server at present , Because ECS is cost-effective , Simple and fast configuration , The easier . In particular, special price cloud servers such as student machines and learning machines provided by domestic giants such as Alibaba cloud and Tencent cloud , Let a large number of novices quickly get to know ECS . Although ECS has many advantages , And cloud server is also the general trend in the future , But do you know why ECS is not suitable for advanced anti DDoS servers ？

In fact, as early as the beginning, cloud servers did not develop at a high speed , Mainly physical machines . Later, after the development of cloud server, we also want to provide advanced anti DDoS services in combination with cloud server , But after practice, at least under the current technology, ECS is not suitable for advanced anti DDoS servers .

One 、 Cloud server unifies many physical machines on a cloud platform through technology , It is divided into independent cloud servers through virtual , Then assign IP For customer use . This leads to one IP The whole cloud platform will be affected when being attacked by super large , This is why many cloud server providers suspend customers when they are attacked IP Reason for use , Because it is necessary to ensure the normal use of other customers .

Two 、 ECS is a virtual split machine , The whole cloud platform is to provide bandwidth for all users , Once one of the customers encounters an attack , At least not in the current situation 100% Ensure the normal access of other customers , The bandwidth will be fully occupied ,CPU house full . This seriously threatens the normal operation of the entire cloud platform . Another important reason is that bandwidth allocation is virtual allocation of the entire cloud platform . Cloud platform takes the cost performance route . The advanced anti DDoS server should take a stable defense route . This leads to the conflict between the two cannot be coordinated .

In the current situation , Physical machine is the best choice for advanced anti DDoS server . Each server exists independently . When adjusting the defense scheme of one server, it will not affect the normal operation of other servers . And the physical advanced anti DDoS server is facing super large DDOS Easier to provide defense when attacking .
