In China with Chinese characteristics of the basic network kidnapped Internet enterprise product experience! Despite the technological level, basic network decided the user experience, can control the good network has become the measure of Internet companies and research and development, testing, operational good or not is an important standard, such as engineers
What about how to manage the network, individual experience is a resource for the king, is simple to understand each IDC or CDN node similar mobile base stations, only guarantee base station near the user experience, the farther the distance, the signal is weak, resources usually has the following two ways:
1. Personal website usually use CDN and lightweight CDN free, free of CDN 360 website (http://wangzhan.360.cn) guards, for example, baidu cloud acceleration (http://yunjiasu.baidu.com), representative of the lightweight CDN have and take cloud (http://www.upyun.com), the above can be different resources and parsing is obtained by free and paid services, (limited to accelerate category)
1) advantage: the free version without cost, can quickly lower barriers to access, to the station to accelerate the immediate, premium for elastic pricing, more suitable for small micro site,
2) disadvantages: less free version of node, resources sharing and unstable factors are even paid version, node is very limited, usually around 30 nodes, & lt; 100 g, overall capacity small,
2. The enterprise website using third-party CDN and self-built CDN, third-party CDN in addition to the traditional web host (http://www.chinanetcenter.com), blue sin (http://www.chinacache.com), the current ali (http://www.aliyun.com), tencent (http://yun.qq.com) the CDN cloud also is on the rise, such as electricity industry mainly use third-party CDN, self-built CDN in addition to the BAT, the video industry is a typical representative of the
1) advantage: third-party special work under the network environment in China for many years, abundant nodes (300 ~ 500 nodes), 2000 ~ 3000 g, size is large, integrated support ability, suitable for large sites,
2) disadvantages: more corporate users sharing of resources, mutual interference, personality and customized support is weak, lack of flexibility and flexible,
Whether the network node distribution is wider, analytical means the smaller the particle size, the better the user experience? Personal experience:
1. The user experience by product value, front-end and back-end code quality, network and system input, even with the engineer's and the pursuit of all relevant professional degree and the network is an important part of them, only to do well the user experience, you need to come to control, such as the BAT has an independent user experience team, professional continuous optimization and keep the user experience,
2. Third-party CDN and enterprise self-built CDN are facing problems, the ratio of best performance versus the lowest cost before the game is the eternal topic, the best performance as far as possible, wide distribution and high quality, not only requires node also requires environment simply no interference (cost), the lowest cost for reuse, most business biggest resource utilization (minimum performance), above all, even the most nodes and the finest resolution strategies are to reach the ideal effect, finally after the actual network benefits are balanced hurt profits,
Unfinished, the next article will share how to test network performance and how to choose the IDC, CDN node and vendors,

Thank you for your sharing, thought the CDN is full of a third party, have never thought, Internet BAT have already built the CDNCodePudding user response:
