This article mainly introduces "what is the necessity of the existence of CDN". In the daily operation, I believe that many people have doubts about the necessity of the existence of CDN. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful for you to answer the question of "what is the necessity of CDN?" Next, please follow the editor to study!

The first and most important problem is the problem of data transmission nodes across operators. There has always been a poor interconnection among China's three major operators, China Mobile, China Unicom and China Telecom. For example, if you are a telecom user and visit a website with an operator of Unicom, the opening speed of the web page will be very slow, and vice versa. After using Diycdn, its acceleration nodes can intelligently identify online sources and high-speed sources, ensure the timely and effective communication, eliminate the impact caused by the bottleneck of interconnection between different operators, and achieve network acceleration across operators.

The second is the slow opening speed caused by the limited bandwidth of the website or the low load of the server. Generally speaking, there may be no problem with the bandwidth and server performance prepared by the website to cope with the usual traffic, but in the event of sudden traffic or peak download, there is nothing you can do about it, resulting in the direct paralysis of the website and affecting the revenue of the website. In the face of this situation, Diycdn uses intelligent shunt load balancing technology, and uses a more effective intelligent redundancy mechanism, which greatly increases the upper limit of node traffic, effectively reduces the pressure of a single node, and can be solved smoothly even if it encounters sudden traffic.

The third is a problem that websites must face nowadays, that is, frequent network attacks. Especially for high-traffic websites, once they encounter DDOS attacks, traffic attacks and so on, the losses are very serious. When Diycdn faces DDOS attacks, the whole acceleration system will disperse all the attack traffic, minimize the pressure on nodes and site servers, increase the difficulty of network hacker attacks, provide more response time for server managers, effectively prevent hackers from invading, and reduce the impact of various DDOS attacks on websites.

Fourth, as the content of the web page becomes more and more abundant, the amount of data transmission increases exponentially, and the opening speed of the website naturally slows down, thus affecting the user experience. Diycdn's solution to this problem is to monitor the whole network, schedule accurate and rich nodes, and dynamically optimize access lines in real time to ensure the state of extreme acceleration.

There must be a reason for existence. In China, although CDN has not thoroughly penetrated into every website, website operators have gradually realized the role of CDN. It is believed that the penetration and coverage of CDN will be greatly increased in the near future.

At this point, the study on "what is the necessity of the existence of CDN" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
