What is the cdn in Beijing Guangzhou Cloud Solution? To put it more generally, cdn [Dutch host] is website acceleration, which can solve the problems of slow website opening and poor user experience caused by cross operator, cross region, insufficient servers and too little bandwidth. Cdn adds a new layer of network architecture to the existing network structure, which stores part or all of the website content on the network service nodes near users, so that users can download the content of nearby websites.
What are the benefits of cdn? After using the cdn service, the response speed of users visiting the website will be fundamentally improved, which is the best way to optimize the website access capability. It solves the bottlenecks and links that may affect the speed and stability of data transmission, making content transmission faster and more stable. Save website bandwidth, reduce server and website pressure, and allocate server resources to more important places. For example, the static resources of the website [ECS] (pictures, js resources, css resources, etc.) are cached in the cdn. Users do not need to obtain static resources from the server website every time they visit. The resources of the server website can be used to meet some requests for dynamic resources. Video, live broadcast, online education and other services consume bandwidth. Such websites and applications on servers have a high demand for bandwidth, but the number of visits and bandwidth supported by a single server is limited. Video websites need cdn to divert and reduce the burden of video servers
The use of cdn in video websites can not only reduce the bandwidth requirements of video servers, but also effectively solve the problem of no communication between China Telecom and China Unicom, hide the real ip address, and protect video servers from attacks. High quality user experience is the key to the success of popular Internet projects such as live video and online education. If images, audio and video are often stuck, huge business opportunities will be lost. Cloud solutions integrating cdn, ECS, load balancing, etc. Build a stable, reliable and high-speed it foundation to provide a solid support for the commercial success of internet enterprises.
What is the cdn in Beijing Guangzhou Cloud Solution? In recent years, American servers are favored by many Chinese webmasters because of their high equipment, low price and free archive space, and their application customers are also increasing. However, some customers found that the download speed of American servers was relatively slow. So, affect the server? What's the reason for the download speed? American servers are highly equipped. Generally, [chat app server] is dominated by independent bandwidth. Therefore, the servers in the United States are particularly suitable for building a platform website for free download of [American fast and stable vps] or online video. However, there are always some factors that will affect the download speed of servers in the United States. The key reasons are as follows:
1. The local bandwidth of the platform website application has a great impact on the download speed of the server, because the Internet is the connection between the mobile phone client and the resource terminal. Like the water pipe, even though the socket of the resource terminal application is large, the socket of the mobile phone client is small, so the download speed of the network server will be limited by the local bandwidth, and the customer's download speed will be very slow. When the local application is private bandwidth, if the application is shared resource bandwidth, the download speed will undoubtedly be affected during the peak period of Internet applications, and even the opening speed of web pages will be affected.
2. The export bandwidth of the server network is usually called the international bandwidth. It is connected between the deep-sea optical cable and the server, and the foreign network host room. Because there are almost no specific export bandwidth operators in China that are open to the public, no matter what bandwidth servers and applications, the export bandwidth of the Chinese connection is the same, and the download speed of customers will also be subject to certain restrictions. Just like the water pipe, it doesn't matter how many pipes you use. The water discharged is operated by the tap.
3. There are several domestic bandwidth service providers for the routing of the host room, so browsing the bandwidth of different routes can only be performed according to several relative sockets. But like the host room network our company established in the United States, the application routing in servers and California means directly connecting China Telecom Network and China Unicom, so the speed will be relatively fast, especially the CN2 routing network server it uses is very fast compared with other routes.
