How to Choose a Server for Self-Built CDN

What is the principle of CND acceleration?

CDN acceleration is by caching the content of the website at the edge of the network (the place closest to the user’s access to the network), and then when the user accesses the website content, the user’s request is routed or directed through the dispatch system to the nearest to the user’s network access. On the best cache server, there is the cache server to provide users with content services; compared to direct access to the origin site, this approach shortens the network distance between the user and the content, thereby achieving an acceleration effect.

Why deploy CND acceleration?

With the development of the Internet, users pay more and more attention to the browsing speed and effects of websites when using the Internet. However, due to the rapid increase in the number of Internet users, the network access path is too long, which seriously affects the quality of users' access. Especially when the link between the user and the website is congested by bursts of large-volume data, poor access quality is an urgent problem to be solved in areas where the number of remote Internet users is rapidly increasing. The purpose of deploying CDN acceleration is to allow users everywhere to have high-quality visits, and to minimize the resulting costs and website management pressure.

How to choose a server for self-built CDN acceleration?

It is necessary for enterprises to build their own CDN server to achieve website acceleration. When general enterprises consider using CDN acceleration, many will choose to rent CDN services provided by service providers. However, there are also demanding customers who choose to build exclusive CDN services through their own servers. In this way, the nodes and IP addresses are all built by themselves, and the right to use the built CDN is only in their own hands, which has higher controllability.

There are also two types of CDNs. The first is for self-use, just to solve the problem of insufficient website bandwidth or slow access speed in certain areas. At this time, the best choice is to set up a node server in the region, and provide content services through the node server when customers in the region visit, as long as the bandwidth and speed of the server can meet your own requirements. The most common application is that overseas servers use CDN to solve the slow access of domestic users. The second type is a CDN service provider who builds CDN acceleration to provide customers with accelerated services. This requires the distribution of multiple nodes of different lines in each area within the business scope to ensure that customers in each area can transmit data through the nearest node of the same service provider. And there are very high requirements for the bandwidth of the node server. When multiple websites use one node for acceleration at the same time, the required bandwidth and traffic are very high.
