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. Today, I would like to introduce the website CDN.

Which is better for the website cdn? At present, the more well-known vendors that provide CDN services in the market are: Aliyun, Internet hostel, Baidu Cloud acceleration, 360Web Guardian, Tencent Cloud, Huawei Cloud, Zaipaiyun, Qiniuyun and so on. Relatively speaking, these sites cdn are better than other small brands.

CDN technology is to help websites accelerate. CDN distributes website content to its nodes. When users visit website content, CDN will assign users the nearest node. In this way, CDN will shorten the distance between users and the host that stores website content, and make the content transmission faster and more stable.

Now the domestic cdn all need to be put on record, which is very strict now. Those who are not on record can only be cdn nodes that go abroad.

1. Many enterprises use free cdn nodes, which are mostly suitable for enterprises with a small number of visitors, and the speed is not fast, but with a little protection against attacks, many of them are public nodes.

two。 If you go straight to cdn in Southeast Asia, it will be more expensive, because the bandwidth in these places will be more expensive.

3. There are also some routing routes, such as Hong Kong routes, which may have to be transferred to Japan first and then return to Hong Kong, which will be much slower, but the price will be lower.

In terms of defense, as ddos attacks become more and more complex, traditional CDN acceleration has been unable to resist large traffic attacks, and demand determines the development of technology. In this environment, ddos high defense services, such as ddos value-added services, can defend against a variety of DDoS attacks and greatly reduce security risks.

The above is a good introduction to the website cdn.
