For those new to the field, CDN ensures that your website's multimedia assets reach the people accessing them without delay. Its role is to complement and enhance your traditional hosting. In this article, we'll take a deep dive into the benefits of CDNs, meaning the factors that make them a high value for businesses of all sizes. You might even say they are the modern heroes of website customer experience.
Anti-DDoS CDN is a server security defense method that integrates acceleration and defense. Operators of high-defense CDN acceleration possible websites are no strangers. It is a content distribution network. A layer of virtual network on top of the foundation.
CDN is a kind of website acceleration. Because the server load capacity is too low and the bandwidth is too small, it will cause problems such as slow website opening speed. The server performance of a website is relatively poor, and the load capacity is limited. The advantage is that it is unable to resist in the face of sudden traffic, which directly causes the server to crash and the website cannot be opened. Therefore, the traditional CDN can no longer meet the daily needs of today's large Internet companies. The full name of CDN is Content Delivery Network, that is, content distribution network. Its purpose is to publish the content of the website to the "edge" of the network closest to the user by adding a new layer of network architecture to the existing Internet, so that users can obtain the required content nearby and improve the response speed of users visiting the website .
Using high-defense CDN can save hosting costs. Today, websites serve a global audience who expect instant delivery of high-quality multimedia files, such as video and animation. This results in greater bandwidth requirements and higher charges by your hosting provider. But the real problem is latency, or delays in loading website pages so people can view them. If users from all over the world are making requests to your origin hosting server, this isn't a problem for small text files, but larger multimedia files are subject to a heavy transfer load that can slow things down. In addition to this problem, a lot of content that travels long distances can suffer from what's known as packet loss, the annoying pauses that occur when you're watching a video and it starts "buffering". The solution is CDN caching - multiple edge servers located in Presence (PoP) around the world that store your website's static content (images and other files). So instead of spreading from one place or one hive, content is served by a swarm of worker bees that are closest to where each user visiting your website is located.
Therefore, there is no longer any waiting time or packet loss, because the high-defense CDN edge server does most of the heavy lifting. Just as importantly, it also means that the bandwidth required by the original hosting provider can be drastically reduced, saving money. In addition to this, a good CDN can automatically reduce the file size of daily site content (such as HTML and text), thus saving even more bandwidth.
