With the rapid development of the Internet, the traffic and visits of graphic and video websites have increased, and the requirements of users for loading speed and access experience have also changed. In order to ensure user experience, CDN has become an important optimization method to accelerate graphic and video websites.

CDN acceleration is the distribution of content to node servers around the world, users access the content from the nearest node, which can greatly reduce latency and improve loading speed. CDN caching static content can reduce the number of direct requests from the source server, reduce the load on the source server, and improve the stability of the overall system. CDN can realize the multi-node distribution of the website, effectively cope with sudden traffic and DDOS tools, and improve the availability and reliability of the website; CDN caching and compression technology can optimize bandwidth usage and reduce operating costs; CDN configuration speeds up page loading and video playback, reduces latency and buffering, and improves user satisfaction and retention.

Choosing the right CDN service provider is the key to providing accelerated photo and video websites, considering global node distribution, service reliability and stability, and technical support. To configure the CDN service, add a new accelerated domain name on the CDN management page. Enter the text or video website domain name, select the acceleration type such as full site acceleration, video on demand acceleration, etc., and fill in the source information.

Select caching rules that meet the requirements of different websites and configure them. For example, pictures and video files can be set for a longer cache time, and dynamic pages need to be set for a shorter cache time or no cache. To ensure data transmission security, you can configure HTTPS acceleration, upload SSL certificates, and enable HTTPS acceleration.

Set control policies, such as anti-piracy link and IP blacklist and whitelist, to ensure content security and compliance. After these configurations are saved, you can start deploying the CDN. The CDN distributes the content of the website to each node, and users can automatically get the content from the nearest node at any time.

You can also optimize the user experience by optimizing graphic and video content. For example, image optimization, use lossless or compression tools such as TinyPNG to reduce image file size and improve loading speed; Using WebP format images will have higher compression rate and smaller file size than traditional JPEG or PNG.

For video optimization, you can compress video files through compression tools such as FFmpeg to reduce bandwidth usage. Provide a variety of resolution and bit rate options, users can choose the most suitable playback quality according to the network status; Enable HLS and DASH and use HLS technology to improve video playback stability and smoothness.

After the CDN is used, the CDN traffic, buffer hit ratio, and user access should be monitored in real time. Use data analytics to optimize policy buffering and content distribution to improve website performance.

Take video websites as an example. Before CDN deployment, video loading is slow and video playback is buffered frequently, resulting in a high user loss rate. After the deployment of CDN, it successfully improved the user experience for the website. The global node distribution is wide, the service is stable, the creation of accelerated domain name configuration cache rules, the enterprise HTTPS acceleration, set anti-theft chain.

Compressed video files can support multi-resolution, multi-bit rate selection, enabling HLS and DASH technology. Real-time traffic monitoring and buffer hit rate, after adjusting the optimization strategy according to the data, the website video loading speed is significantly improved, the number of buffering is reduced, the user churn rate is reduced, and the user satisfaction and retention rate are greatly improved.

CDN speeds up graphic and video websites to greatly improve user experience, reduce server load, and improve website availability and reliability. Appropriate CDN services, reasonable configuration of buffering and access control strategies, optimized content and real-time monitoring and analysis, can achieve efficient content distribution, ensure stable operation and rapid response of the website.
