With the rapid development of the Internet, CDN (Content Delivery Network) technology has gradually become an important network service. As one of the CDN brands, the content stored on its servers has also attracted much attention. This article will introduce in detail the content stored by the Supershield CDN server, as well as its role and significance for the Internet.
1. Overview of the CDN server.
The CDN server is a caching system based on globally distributed deployment, which provides a faster, more stable, and more reliable access experience by distributing content to edge nodes close to users. The storage content of the speed shield CDN server mainly includes static resources, such as HTML pages, etc. These resources are automatically cached on CDN nodes when users access them, so that they can quickly respond to user requests.
2. The type of content stored by the CDN server.
1.Web content: The CDN server stores a large amount of web content, including HTML pages, CSS style sheets, and J**Ascript scripts. These contents are the basic elements that make up the **, and by caching these contents on the CDN node, the loading speed and stability of the ** can be greatly improved.
2.Footage: is one of the most storage space resources in the world. The CDN server will store a large number of ** materials, including thumbnails, high-definition large images and other versions of different specifications, so as to quickly respond to user requests. At the same time, the Supershield CDN server will also provide automatic scaling and cropping functions to meet the display needs of different devices.
3.Resources: With the rise of the Internet, there is an increasing need to provide services. The Supershield CDN server will store a large number of ** resources, including movies, TV series, variety shows, etc. By caching on the CDN node, you can greatly improve the loading speed and experience. At the same time, the CDN server will also provide transcoding and format conversion functions to meet the needs of different devices and processors.
4.Other static resources: In addition to the above, the Supershield CDN server will also store some other static resources, such as font files, audio files, etc. Although these resources occupy a small amount of storage space, they also have an important impact on the integrity and user experience.
3. The role and significance of the CDN server.
By distributing the content to the CDN server, the following benefits can be bringed:
1.Accelerated access speed: Because the CDN node is close to the user, the user can get the content they need faster when accessing, which improves the loading speed and response time. This has important implications for both user experience and search engine optimization.
2.Reduce the pressure on the origin server: By distributing a large number of user requests to CDN nodes, you can reduce the load on the origin server and reduce the bandwidth cost and operating cost of the origin server.
3.Enhance stability: Because CDN nodes have fault tolerance mechanism and load balancing functions, when a node fails, it can be automatically switched to other available nodes, thus improving the stability and availability.
4.Improve security: By caching content on CDN nodes, you can reduce the direct exposure of the origin server and enhance security. At the same time, the CDN server also provides a variety of security features, such as anti-leeching, anti-DDoS attacks, etc.
5.Cross-regional coverage: The globally distributed deployment of the Supershield CDN server enables it to cover a wide range of user regions, and users can quickly access the best content no matter where they are. This is especially important for those who operate across borders or geographies.
6.Better support for multi-content: For the transmission of multi-content, such as audio and so on, the size of the network bandwidth has a great impact on its transmission speed. By using the CDN server, the transmission efficiency of the content can be greatly improved and the delay problem in the transmission process can be reduced.
