Of course you have hired CDN services, but it is not necessary that you know about the way they function. CDN stands for Content Delivery Network and just like you know about its benefits, since you have been making a good use of its advantages, you must know about the way it works. Even though it is not possible for you to have an in-depth knowledge about how CDN works, it doesn’t mean you can’t know even a bit of it. We are here to tell you about how CDN works so that you are equipped with a good amount of knowledge related to the services you have been using.
Whether you are using video CDN or any other CDN, the process in which CDN works is somewhat same. Here is how it works:
If the distance between the server of your website and the visitors is way too much, it is not possible for them to stream videos effectively and quickly. Thus, you need to do something with the help of which the video content can be streamed and delivered as quickly as the textual content. This is the only reason why more and more people are focusing on CDN services, since they provide you with solutions for such situations.
In order to minimize the total distance between the server of your website and the visitor, there is a cached version of the content stored at CDN. This cached version is stored at various geographical locations. This process is also known as Points of Presence, the abbreviation of which is PoP. Every single PoP has various caching servers. The function of these caching servers is to deliver the content just when they visit the website. The PoP releases the content when the visitors are within its proximity or geographical distance. This makes it easier for the visitors to stream the videos at a much lesser time. They find it easy to continuously watch the content, without waiting for the casual “buffering” period.
The truth about CDN, that many business houses and individuals don’t know, is that it ensures to put the content in different places and that too all at once. It provides your user with superior coverage. Thus, when the user is watching the video on your website, he doesn’t have to wait for the content to come from your web server; it comes through PoP.
