Is it Good to Build your own CDN?

With the development of the Internet, users pay more and more attention to the access speed when visiting websites. In order to allow visitors from different regions to browse the website quickly, CDN acceleration service was born. CDN can not only reduce network congestion, improve user access response speed and hit rate, and because many users no longer go through the source site when accessing website content, CDN also has the function of hiding the source site IP. CDN can be divided into self-built and others.

Self-built CDN means that the content provider rents bandwidth and hosting service by itself, and develops and manages the corresponding CDN system and platform by itself. Self-built CDN requires a content provider with a large enough scale to support a network-wide CDN service. At the same time, it has considerable technical strength and maintenance strength. The requirements are relatively simple and clear, the complexity is not high, and the customization is strong.

Most of the self-built CDN systems are based on some kind of open source system, and are developed and designed according to their own individual needs, so as to better meet the needs of content operation.

1. The cost of completely self-built CDN is too high

The initial investment is relatively large, requiring a large amount of capital, and it will also increase the company's operating and R&D costs. For non-core business companies, self-built CDN networks can easily disperse the company's experience in their main business, which will affect the main business to a certain extent.

2. The network construction period is too long

A well-operated CDN technology will be more complicated, not only will it take more energy, but also will have more expenditures on manpower and financial resources, while a well-made CDN on the market will be more convenient and cost less.

3. The technical level of technical personnel is strictly required

Self-built CDN needs to master not only the principles of CDN, but also detailed steps and professional knowledge, such as knowing how to operate the CDN system architecture, and precautions, etc.

Self-built CDN or commercial CDN often depends on our comprehensive measurement of quality, customization ability, cost and other aspects. Self-built CDN has advantages and disadvantages, and there are many pitfalls, so choose carefully!
