This article introduces the relevant knowledge of "what are the differences between domestic and foreign CDN". In the operation of actual cases, many people will encounter such a dilemma. Next, let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Due to the differences in the network environment at home and abroad, the meaning of CDN (content distribution network) is also different. In China, the main problem solved by CDN is the interconnection between operators, of course, it does solve the problems of sudden traffic, large-scale coverage and slow Internet access. Therefore, the most obvious domestic demand for CDN is large Internet companies, especially video, games, portals, e-commerce and so on. Enterprises relatively understand very little, only a few foreign-funded enterprises can understand the true meaning of CDN, domestic enterprises still need a long time to understand. In foreign countries, a considerable part of the customer group of Akamai is enterprises, all kinds of enterprises which are not directly related to the Internet.

Personally, I think there are the following points about the good and bad of CDN: (regardless of the first and the second)

1, infrastructure investment, that is, the quality and quantity of nodes; (so small CDN service providers are naturally at a financial disadvantage)

2. Technology R & D investment, sensitive to new technologies, sensitive to Internet traffic, sensitive to IP network underlying technology; more and more dynamic data, how to accelerate for dynamic technology, how to effectively separate dynamic and static, how to automatically identify and distinguish different services, how to schedule traffic intelligently, and so on.

3, a deep understanding of the business of Internet companies, for games, video, portals, e-commerce and other Internet companies, what are the unique needs of different business types, and how should services and products actually solve problems? how to make customers really feel convenient, practical and efficient.

4, service awareness, how to continuously improve the efficiency of the background system, how to give customers a really convenient and simple operation interface, how to use bandwidth and other data to count out more valuable information to give feedback, and how to make CDN services relatively transparent instead of becoming a kind of work pressure on the operation and maintenance department.

5, data talk, accumulated so much data, what kind of feedback, what kind of summary and induction, can extract what is more valuable to customers, whether you can find the problems of the current system and solve them as soon as possible.

6, operation experience, operation and maintenance friends all know that experience is very important. Therefore, the service time of a CDN service provider is very critical, as an old saying goes, eat more salt than you walk, can it be the same? Of course, experience is not a simple accumulation of time, it should be a process of continuous summary and improvement, which is of great significance.

Some views:

1, billing standard, because the monopoly position of domestic operators is indisputable, so a large part of the billing method is affected by operators. Akamai is billed by traffic, but in China, it has to be billed mainly by bandwidth.

2, the price is high or low, if you simply resell the bandwidth of the operator to the Internet company, then CDN will become a bandwidth wholesaler, the price is naturally just the price, there is no other value. But if you can combine a large amount of data and enhance the experience technologically, there will be more value, and the price will naturally be high.

3. Avoid the vicious circle, which begins when the added value of products and services is too low. People who buy things only look at low prices, those who sell things have to keep cutting prices, and those who buy things find that the quality is getting worse and worse, so they have to look for lower prices, and those who sell things have to constantly reduce costs and reduce input. In the long run, the consequences can be imagined.

Something that I personally think is valuable:

Traffic scheduling, which is simple to say, can achieve global scheduling like Akamai, which is not easy.

Dynamic data, at present, domestic CDN service providers do not have a really practical and easy-to-use solution, which requires continuous technical investment.

A high degree of automation, the efficiency of a system or even a company directly affects the results.

Attitude, whether you think only for yourself, or whether you can really think about things from the point of view of the customer, is very important.
