The importance of choosing the right CDN and understanding what CDN is –Helpful tips from Space CDN
CDN is a very important feature that can be found through the long list of implementations used by top ranking websites. The reason for this is that it ensures a very important quality which, today, cannot go missing from the functioning of a website if you want that specific website to pull in numbers or be recognized positively within the online community. In this article we are taking a look at how CDN works and what you can expect from it before looking into any cdn comparison.
What is CDN?
CDN is short for Content Delivery Network and it can efficiently be described as an intricate web of servers spread across a large area of the world that helps with the delivery of online content from the main server to any site request with excellent loading speeds. To put it in more simple terms, it helps websites load faster even if you’re accessing contents from a server that is very far away. There are companies or websites that have servers all over the world, so accessing their official website swiftly isn’t a problem. But others only have one server to rely on and thus are unable to solely guarantee the speed efficiency of every single site loading request. This is where CDN comes into play as it allows users to draw content from the CDN server situated in proximity rather than the original server.
What are the types of CDN?
There are two main types of CDN. Both of them are important and they are equally efficient in their own preferred environments. Let’s take a look at what these types are and more importantly what are the environments in which they bear the most fruit.
Push CDN can be characterized as the swift solution for any small website that wants to make itself more approachable and load speed efficient towards more geographically distant visitors. On websites that don’t see a lot of traffic on a day by day basis, Push CDN is great because domain administrators have full control of the CDN server and set all the details regarding what content from the original server ends up on the CDN one, for how long and in what conditions. There aren’t a lot of refreshes so there are less wasted resources.
Pull CDN can be great for the opposite situation where the website is anything but small. Large websites are best described by the huge numbers that they manage to pull in daily. These users make it so the website needs constant updates ant regulated intervals. Pull CDN provides this by settings “update appointments” with the original server then grabbing information automatically at these intervals. The site administrator is not in control of when these updates occur or how frequent.
