Content distribution network (Content Delivery Network, referred to as CDN) is a distributed network, which is established and covered on the bearer network, and is composed of server groups of edge nodes distributed in different areas. CDN shares the pressure on the origin server, avoids network congestion, ensures that the distribution of website content is accelerated in different regions and different scenarios, and improves the speed of resource access. Many users will encounter the problem of how to make effective use of CDN in the process of actual use of CDN. Today, I will introduce the effect of CDN in website acceleration.

What about cdn? Most people know that when a user opens a new website, if the opening speed of the website is too slow, it is difficult for the user to continue to browse, so many website operators try to improve the loading speed of the website. CDN is an effective and practical way to help a website open quickly.

Reason why the website slows down

The slow opening speed of a website is affected by many factors. Here are a few common reasons:

1. The shared host server is overloaded and slow to respond.

two。 The pictures and content of the website are so large that it takes a lot of time to download.

3. The site uses too many different scripts and images, which are not optimized for fast loading sites and take a long time to load

4. The server location of the website is in a different geographical location from the visitors to your site.

The accelerating effect of cdn

CDN refers to the content distribution network, and its basic idea is to avoid the bottlenecks and links that may affect the speed and stability of data transmission on the Internet as far as possible, so as to make the content transmission faster and more stable.

By placing node servers everywhere in the network to form a layer of intelligent virtual network based on the existing Internet, the CDN system can redirect the user's request to the nearest service node in real time according to the comprehensive information such as network traffic, connection of each node, load status, distance to the user and response time. Its purpose is to enable users to get the content they need nearby, solve the situation of Internet network congestion, and improve the response speed of users visiting the website.

In short, CDN is better suited as a network to handle website traffic than most hosting services, and CDN's main goals and actual infrastructure settings are designed to help provide lightning-fast websites.

Virtual hosts can enjoy Baidu's massive CDN node resources free of charge, rich node resources, covering the whole world, and provide acceleration services for a large number of users with unlimited traffic. High-speed and stable virtual host product link https://www.yisu.com/cloud/
