Compared with other CDN service providers, the main advantages of CDN include stable and fast, cost-effective, easy to use, efficient and intelligent. More users will ask about the advantage of stability and speed. Generally speaking, CDN is characterized by sharing the pressure on the origin server, avoiding network congestion, accelerating the distribution of website content in different regions and different scenarios, and improving the speed of resource access. Today, I will tell you what are the problems often encountered in the specific use of cdn.

What are the common questions about cdn? Cdn is an advanced traffic distribution network based on the existing Internet. More and more websites are using cdn technology. Let's take a look at common cdn-related questions.

What type of website needs CDN?

Suitable for target customers to cover nationwide websites, all require quick access to customer websites to thoroughly solve the problem of north-south interconnection. In addition, for foreign websites, if they need to improve the speed of visiting China, due to the obvious differences in speed at home and abroad, CDN will also have an immediate effect on their speed.

Is CDN acceleration accelerated for servers or domain names?

CDN is only accelerated for a specific domain name of the site. If there are multiple domain names on the same website, visitors will not be able to get the CDN effect if they visit the domain name that joined CDN, or if they visit the domain name that has not joined CDN, or if they visit the IP address directly.

What are the advantages of CDN over mirror sites?

CDN is completely transparent to the visitors of the website, and there is no need for visitors to manually select the mirror site to visit, which ensures that the website is friendly to visitors. CDN has an availability check for each node, and unqualified nodes will be removed as soon as possible, ensuring a high availability rate, while the mirror site cannot be implemented. CDN is easy to deploy and can take effect without making any changes to the original station. CDN nodes are widely distributed, and it is difficult for mirror sites to achieve the same coverage.

What is the difference between CDN and two-line computer room?

The double-wire computer room is a unique product in the special domestic network environment. The double-line computer room can only solve the bottleneck of Netcom and telecom access, but the link problems in network transmission and other ISP interworking problems have not been completely solved. The principle of CDN is that users visit nearby and visitors get data nearby, which greatly shortens the transmission distance between visitors and the origin server, and can solve the problem of slow network transmission.

The above is a summary of frequently asked questions about cdn.
