Where is the CDN set? CDN novice tutorial

With the rapid development of digitalization, the speed and stability of websites have become an important standard to measure user experience. CDN (Content Delivery Network), as a key technology to improve website performance, is being paid more and more attention by website managers. So, where is the CDN set? For beginners, how to use CDN quickly? This article will give you detailed answers, and take you into the world of CDN easily.

1、 CDN Introduction and Advantages

CDN is a technology to speed up content transmission and improve website response speed by deploying a series of cache servers on the Internet to pre store the content requested by users on the nearest server. The advantages of CDN are mainly reflected in the following aspects:

Accelerate content transfer : CDN reduces the data transmission distance between the user and the source server through the caching mechanism, thus reducing the network delay and improving the content transmission speed.

Improve user experience : Fast loading pages and smooth video playback can significantly improve user satisfaction and reduce user churn.

Reduce source server pressure : CDN shares the access pressure of the source server, enabling the source server to focus more on core business.

2、 CDN setting steps

Select CDN service provider : There are many CDN service providers available on the market, such as Alibaba Cloud, Tencent Cloud, Huawei Cloud, etc. When selecting, we can consider comprehensively according to our own needs, budget, reputation and technical strength of service providers.

Register an account and log in : After selecting a CDN service provider, go to its official website to register an account and log in.

Create CDN acceleration domain name : In the CDN management background, select the "Create an accelerated domain name" function and fill in the domain name information to be accelerated. Note that the domain name needs to have been filed and resolved to the CNAME address provided by the CDN service provider.

Configure cache policy : Configure appropriate cache policies according to business requirements. Including cache time, cache file type, etc. The reasonable configuration of cache strategy can effectively improve the acceleration effect of CDN.

Enable HTTPS acceleration (optional) : If the website needs to support HTTPS access, you can enable the HTTPS acceleration function in the CDN management background. CDN services will provide free SSL certificates or support users to upload custom certificates.

Test and optimization : After setting the CDN, conduct a visit test on the website to ensure that the CDN acceleration effect is normal. At the same time, optimize and adjust the cache strategy and other configurations according to the test results.

3、 Precautions for CDN use

Clean cache regularly : To avoid cache expiration or pollution, it is recommended to clean the CDN cache regularly.

Monitor CDN performance : Use the monitoring tools provided by CDN service providers to monitor the performance and stability of CDN in real time to ensure that the website always keeps the best status.

Pay attention to safety protection CDN service providers usually provide security functions such as DDoS attack protection and CC attack protection. It is recommended to enable relevant functions to improve the security of the website.

As an important technology to improve website performance, CDN has significant advantages in improving user experience and reducing the pressure of source servers. Through the introduction of this article, I believe you have a preliminary understanding of the setting and use of CDN. In practical application, further exploration and practice should be carried out according to their own business needs and technical strength. Let's work together to make the website more powerful with the help of CDN!
