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 several kinds of free CDN in China.

The CDN (Content Delivery Network) listed here is an experimental version that can be used for free. If you need more professional features and services, please upgrade the paid version. If the price of each CDN is different, it will not be listed one by one. Now let's take a look at a simple comparison of the various CDN that are available for free:

It is found that FreeCDN (su.zhiduopc.com) can simultaneously provide DDOS defense, CC defense and support HTTPS/SSL certificate and unlimited traffic. This is the only one that can provide this kind of free service. Most of the others are limited or do not provide DDOS defense / CC defense, and few can support HTTPS/SSL certificate.

Applied for a use is not bad, the background interface is simple, easy to operate. Unlimited 1.8T defense supports pan-parsing + custom HTTPS/SSL+ cache acceleration, ignoring CC without man-machine verification.

If there is anything else you need to know, you can find our CDN technical engineer on the official website. CDN technical engineer has more than ten years of experience in the industry, so it will be more detailed and professional than the editor's answer. Official website link www.yisu.com
