What is CDN?

CDN in short, stands for content delivery networks. CDN is now widely used as it is designed to solve latency issues – one of the most annoying issue occurs when you are trying to consume contents from other countries in the world. This is because, the further you are, the higher the latency you will suffer from – for example, Los Angeles, US to Kuala Lumpur, Malaysia has an average latency of 250ms. And this affects your content quality – imagine you are streaming, but every 2 second, the video stopped to buffer from Los Angeles as it requires to pull the content from such far away location.


This is CDN’s mission – to virtually shorten the physical distance and the goal being to improve site rendering speed and performance.



  How does this magic work?

CDN works by provider deploying different “POP” in different country, and these POP serves as a cache server for your contents. The same scenario, content originated from Los Angeles to Kuala Lumpur. But this time, the provider installed a POP in Kuala Lumpur itself. All your contents, will be pulled from Los Angeles to this POP, and you stream directly from the POP server. The latency in between your location, to the POP – will be around 10ms, in which your contents stream without any buffer.
