This article focuses on "how to understand one of the core technologies of CDN: load balancing". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let the editor take you to learn "how to understand one of the core technologies of CDN: load balancing"!

CDN is an effective means to solve the problem of website acceleration, which first sprang up and developed rapidly from the United States in recent years. With the increase of domestic broadband network users and the growth of network video business, in just a few years, domestic CDN technology has developed rapidly, and many websites have begun to use CDN services to improve website speed, improve service quality, and bring better access experience for network users.

CDN mainly adds a new network architecture to the existing Internet to 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 and improve the speed of users to visit the website. One of its core technologies is CDN load balancing technology.

CDN load balancing is based on the existing network structure. It provides a cheap, effective and transparent way to expand the bandwidth of network devices and servers, increase throughput, enhance network data processing capacity, and improve network flexibility and availability. Its specific meaning is to distribute to multiple operation units for execution, such as Web server, FTP server, enterprise critical application server and other critical task servers, so as to complete the task together. To put it simply, the client sends the request to the server, but one server cannot afford high concurrency, so it will forward the request to other servers. Of course, the real load balancing architecture is not another server forwarded by one server, but a load balancer hardware responsible for distributing requests is added between the client and the server.

In the CDN acceleration system, CDN load balancing is divided into server load balancing and server global load. In the CDN scheme, the overall load balancing of the server plays an important role, and its performance will directly affect the performance of the whole CDN, which can not be ignored.

At this point, I believe you have a deeper understanding of "how to understand one of the core technologies of CDN: load balancing". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
