What is a CDN?
Posted: Wed Jan 22, 2025 8:38 am
The full name of CDN is Content Delivery Network. It is mainly a network composed of one or more servers distributed around the world. It provides Internet content serialization, enables fast and stable data transmission, and improves the website's performance. Speed and availability. When a user visits a website, the CDN will automatically select the server closest to the user to provide content, which can improve the speed and efficiency of the website. A configured CDN can also help defend against DDoS attacks (distributed denial of service attacks) and prevent network system abnormalities.
For example, there is an ABC website whose servers are located in the United States. There is a 1MB image on the website. When Taiwanese users visit the website, it takes a long time to download the image due to the long distance. If ABC uses CDN services, the images will be copied to CDN servers around the world, such as Taiwan, Japan, Hong Kong and other places. When visitors from Taiwan visit the ABC website, their requests will be distributed to the nearest CDN node, such as the CDN server in Taiwan. The images on the server will be loaded quickly, and the speed and stability of the website will also be greatly improved.
CDN service
CDN service is based on a distributed system. CDN service providers el-salvador phone number list will deploy a large number of servers around the world. These service providers will have a huge network. Servers are typically located in major cities and Internet exchange points around the world to deliver content to users' devices quickly and efficiently. Another important feature of CDN service is that it can alleviate the impact of network congestion on website performance. It can disperse access traffic to different servers by dispersing the load, thereby improving network loading speed and user experience.
4 main reasons why you should use a CDN!
1. Improve website loading speed
CDN can distribute website content to global nodes. When users access the website in different regions, they can obtain data from the node closest to them, reducing data transmission time and improving website loading speed. For example: when a company in Taiwan wants to enter the Chinese market, using CDN can allow their website content to be uploaded to the local node in China. When users in France access the website, they can directly obtain data from the Chinese node, reducing The time it takes to transmit data from Taiwan.
2. Reduce server load
When users access content on the website, the server needs to bear a greater load. Especially when the traffic is heavy, the traffic may cause the server to crash. However, using the CND service can distribute website content to global nodes, allowing different nodes to handle different requests, thereby sharing the load on the server. For example: When a Taiwanese manufacturer launches a new product in the Chinese market, the stability of the website may be affected due to excessive website traffic. However, using CDN can transfer part of the access traffic to the CDN node for processing, reducing the burden on the server and improving the efficiency of the website. Website stability and reliability.
For example, there is an ABC website whose servers are located in the United States. There is a 1MB image on the website. When Taiwanese users visit the website, it takes a long time to download the image due to the long distance.
