How to choose CDN service provider

Due to the different network environment at home and abroad, the meaning of CDN (Content Distribution Network) is also different. In China, the main problem that CDN solves is the interconnection between operators. Of course, it does solve the problems of sudden traffic, wide coverage and slow access of netizens. Therefore, the most obvious demand for CDN in China is large Internet companies, especially video, games, portals and e-commerce. There is relatively little knowledge about enterprises. Only a few foreign-funded enterprises can understand the true meaning of CDN, and it will take a long time for domestic enterprises to understand it. In foreign countries, a considerable part of Akamai's customer base is enterprises, all kinds of enterprises that are not directly related to the Internet. The advantages and disadvantages of CDN are as follows: (in no particular order) 1, infrastructure investment, that is, the quality and quantity of nodes; (So small CDN service providers are naturally at a disadvantage in terms of funds) 2. Investment in technology research and development, sensitivity to new technologies, sensitivity to Internet traffic, and sensitivity to the underlying technologies of IP networks; There are more and more dynamic data, how to speed up dynamic technology, how to effectively distinguish between static and dynamic, how to automatically identify and distinguish different services, how to intelligently schedule traffic, etc. 3. Have an in-depth understanding of the business of Internet companies, and what are the unique needs of different business types such as games, videos, portals and e-commerce for Internet companies. How to truly solve problems for services and products, and how to make customers feel convenient, practical and efficient. 4. Service awareness, how to continuously improve the efficiency of the back-end system, how to give customers a truly convenient and concise operation interface, how to use bandwidth and other data to count more valuable information for feedback, and how to make CDN services relatively transparent instead of becoming the work pressure of the operation and maintenance department. 5, data speak, accumulated so much data, what kind of feedback, what kind of summary, what can be extracted that is more valuable to customers, can you find and solve the problems of the current system in the first time. 6, operational experience, friends who do operation and maintenance know that experience is very important. Therefore, the service time of a CDN service provider is very important. As an old saying goes, you eat more salt than you take. Can it be the same? Of course, experience is not a simple accumulation of time, but a process of continuous summary and continuous improvement, which is of great significance. Some opinions: 1, charging standard, because the monopoly position of domestic operators is beyond doubt, and the charging method is largely influenced by operators. Akamai charges according to traffic, but in China, it mainly charges by bandwidth. 2. The price is high and low. If the bandwidth of operators is simply resold to Internet companies, CDN will become a bandwidth wholesaler, and the price is naturally only the price, with no other value. However, if we can combine a large amount of data and improve the experience technically, it will be more valuable and the price will naturally be high. 3, to avoid a vicious circle, when the added value of products and services is too low, the vicious circle begins. Those who buy things only look at low prices, and those who sell things have to keep reducing prices. The quality of shopping is getting worse and worse, so they have to find lower prices, and those who sell things have to cut costs and reduce investment ... In the long run, the consequences can be imagined. Personally feel valuable: traffic scheduling, to put it simply, is not easy to achieve global scheduling like Akamai; Dynamic data, at present, domestic CDN service providers have no real practical and easy-to-use solutions, and need continuous technical input; High degree of automation, the efficiency of a system or even a company directly affects the results; Attitude, whether it is only for yourself, whether it can really consider the problem from the perspective of customers, is very important.
