For websites that want to reach the highest peaks of success known on the online spectrum, it is very important to implement CDN solutions which help remove any unnecessary delay between the moment when a user requests information and the moment that information is delivered to them. In other words, the top websites in the world use CDN to increase their loading speeds substantially by allowing for increased optimization and server-based prioritization. There are two main types of CDN services, and while both will improve your site’s loading speeds, choosing the right one will yield further positive results. The difference in performance is very noticeable between the two when choosing the one right for the job, so taking the time to determine what kind of CDN your website will most benefit from will pay off big time as opposed to just picking one since both do your domain good. Let’s take a look at what the two types of CDN are.
Choosing the right CDN for every website
This form of CDN acts on a solid principle: It relies on the user uploading content manually to the CDN server, and that content is only used when necessary as opposed to being constantly refreshed and re-accessed. Since the user is in control of when content is being uploaded to the CDN server, they are also responsible for all the other details that come with the job such as setting an expiration date and when the content gets a much-needed refresh or update.
Pull CDN services work almost in an opposite manner than Push CDN in the sense that it relies on the CDN server getting data from the main server. While with Push CDN users have to manually upload the content they want to be pushed to CDN servers, Pull or Origin CDN as it is also called will automatically retrieve content at set intervals. It will pull the necessary data from the main server whenever it is requested.
So which is the best one?
As mentioned previously, neither is better than the other. Both excel in different situations which make it important for the user to know what type of CDN is the best for their particular situation. To be more specific, Push CDN is great for low traffic websites where there isn’t such a high demand for content to be refreshed. Users upload content once and don’t have to deal with updates regularly. Pull CDN, on the other hand, works best on high traffic websites as it will retrieve the relevant information requested by users each time this happens, continuously refreshing with content from the main server. It is a type of CDN that would cause a higher amount of wasted resources if implemented on a low traffic website where there is no need for some of its characteristics.
