Content Delivery Network (CDN) brings the static content of your website closer to the global users, using point based servers.
In other words, it reduces the distance between the original hosting servers and the destination computers, by placing several connecting or point servers in different parts of the world.
These servers then cache some of your website’s elements and distribute them to their ‘nearest local servers’.
This technique not only helps in decreasing both page-load times and the bandwidth costs, but also reduces the stress on the original server, while enhancing the customer experience.
Wondering which are the best CDN providers 2021? Let’s get started.
