Content distribution network (CDN) uses intelligent routing and traffic management technology to find the accelerated node that can provide the fastest response to visitors in time, and forward the visitor's request to the accelerated node, and the accelerated node provides content services. The CDN system uses mechanisms such as distribution and replication to manage the content. CDN customers do not need to change the original website structure, but only need to modify a small amount of DNS configuration to improve the response speed of the website.

1. Advantages of using CDN

1. Deliver content faster

Because the CDN is placed closest to the user, you can reduce latency when your content needs to move shorter distances. CDN can make your website load faster. For example, if your website is located in the UK and you receive traffic from the United States, your CDN provider may have a server in the United States and use it for your site.

2. More synchronization users

CDN ensures that the network has a high data threshold. Therefore, a large number of users can access the network at the same time without delay. By achieving high traffic, CDN allows people from all over the world to visit your website at the same time.

3. Continuous availability

The server in CDN is always running, and your website can be accessed even if the server is turned off. Without CDN, your server may sometimes shut down, which means you have to wait for the host to resolve the problem. If you use CDN, this will not happen. If the server crashes, CDN will use your cache page.

4. Reliable content delivery

If you use CDN, the delivery of content is more consistent. In particular, this involves high-resolution content, such as video and images. CDN provides high-quality content delivery, which has a significant impact on the performance of your site. Because 54% of customers want to see videos on your website, it is critical for your business that you can provide these videos in high resolution.

5. Control asset delivery

When CDN monitors your asset delivery, operators can determine where additional capacity is needed based on real-time statistics. If servers in an area are overloaded, operators can provide additional bandwidth to ensure that everything runs smoothly.

6. Prevent traffic peak

If you suddenly see a lot of traffic on your site, you can benefit from CDN services. A large server network ensures that these resources are available and scalable in all cases. The nightmare for many companies is that they will get a significant increase in traffic, but their websites cannot handle it.

Second, the principle of CDN

The basic principle of CDN is that all kinds of cache servers are widely used, and these cache servers are distributed to the areas or networks where users are relatively concentrated. When users visit the website, the global load technology is used to direct the user's access to the nearest working cache server, and the cache server directly responds to the user's request.

The basic idea of CDN 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.

What are the advantages of cdn? So much for sharing here. I hope the above content can be of certain reference value to everyone and can be put into practice. If you like this article, you might as well share it for more people to see.
