I have used Qiniu Cloud CDN for several years before. HTTPS was not very popular at that time, so it is very good to use Qiniu Cloud CDN to accelerate HTTP static files. The price is cheap and there are many domestic nodes. And it seems that Qiniu Cloud is the first to launch the mirror storage function, which can achieve seamless connection with CDN acceleration services. Nowadays, there are more and more major cloud storage merchants, and everyone’s choices are also diversified. In addition to Qiniu Cloud, others such as Youpai Cloud, Alibaba Cloud, Tencent Cloud, etc.
