In the process of website loading speed optimization, it is inevitable to use CDN to speed up resource request speed. However, almost all CDN resources on the market are charged, and the price is not cheap. For small company webmasters, this will be a big expense. However, there are still some conscientious companies that provide us with free resources. This article will introduce several CDNs that can be prostituted for free and use them to compare speeds for everyone. I hope it can help you.
Baidu Cloud CDN
Baidu cloud acceleration is divided into free version and paid version. The free version does not support SSL certificates, and overseas websites also support acceleration. Baidu Cloud Acceleration claims that it can accelerate Baidu's indexing, but the effect is not very obvious. Cloud Acceleration also provides free domain name resolution services. Please note that Baidu Cloud Acceleration is a different product from Baidu Cloud and Baidu Cloud Disk, so don't be confused by the confusing names. It is said that Baidu Cloud Acceleration can also use unregistered domain names, but it is reported that during the use of domain names without BA numbers, their CDN acceleration nodes will be transferred to foreign countries, which will greatly reduce the CDN acceleration effect.
According to the editor’s speed measurement, the average speed of Baidu Cloud CDN after speed measurement is 62.7ms, which requires a registered domain name, supports SSL, and the traffic is 5G/day (fast in China, not slow in foreign countries)
CloudFlare
Cloudflare is a global cloud platform designed to make everything you connect to the Internet safe, secure, fast and reliable. CloudFlare can help the protected site defend against most network attacks including denial of service attacks (Denial of Service), ensure that the website is online for a long time, and at the same time improve the performance and access speed of the website to improve the visitor experience.
According to the speed measurement, the average speed of the free version of Cloudflare is 111.5ms, but it should be noted that you need to change the DNS to it, support SSL, no need to file, and the traffic is unknown (it is a little slow in China, but it is very fast abroad)
Fire Umbrella Cloud CDN
Fire Umbrella Cloud Converged CDN is based on the traditional CDN, and integrates the high-quality nodes of the world's mainstream CDN manufacturers through technical means, so as to realize the intelligent scheduling acceleration management service of the full business processing capacity. The integrated CDN comprehensively utilizes the above-mentioned Resources can be used to solve problems in actual scenarios, which can bring better service effects, more stable quality and relatively lower service costs. Huosanyun mainly uses the nodes of Alibaba Cloud and Tencent Cloud in China. The free quota is 100GB, but its basic package is also relatively affordable. You can buy 100GB of domestic traffic for about 10 yuan. What is more special is that Huosanyun also offers It supports network acceleration in unlimited regions around the world and acceleration of returning to China without filing, and supports nodes of many mainstream manufacturers such as Alibaba Cloud/Tencent Cloud/Wangsu Cloud/Baishan Cloud/CloudFount.
After speed measurement, the average acceleration speed of Huosanyun Cloud is 62.4ms. If you choose a domestic manufacturer, you need to complete the filing, support SSL and can apply for an SSL certificate for free.
Qiniu Yun
Qiniu cloud storage has a wide range of applications. Whether it is Wordpress or Discuz forums, static files such as pictures and attachments can be accelerated using Qiniu cloud storage. For websites with many pictures and attachments, Qiniu cloud storage is the first choice! Because it is one of the brands that professionally provides static CDN acceleration services, Qiniu cloud storage free package service can be used regardless of pictures, audio and video, streaming media, files, etc.
Qiniu Cloud can use 10G of free storage, 10G of CDN traffic and 1 million Get requests per month. Qiniu Cloud also has many acceleration nodes overseas. Qiniu Cloud’s TCP compression optimization enables large images and styles in web pages Wait for seconds to load. But please note that to use Qiniu CDN, you must ensure that you have a minimum amount of 10 yuan in your account.
After speed measurement, the average acceleration speed of Qiniu Cloud is 58.9ms, which must be filed in China and supports SSL.
in conclusion
If it is a small website that has been filed in China and the traffic is not very high, Baidu Cloud Acceleration is recommended first, and the overall acceleration performance is the best. If your website has not been filed, it is recommended to choose Huosanyun, which supports global unlimited regional network acceleration and free of filing When returning home to accelerate, the network acceleration is even better than CloudFlare. But if you also need DDOS and CC protection, then CloudFlare is undoubtedly a more suitable choice.
