Benefits of CDN, Content Delivery Network

Now let me explain to you by giving an example on What is Content Delivery Network and what are the benefits of CDN and How CDN works?

Usually, bloggers or any website users use a shared hosting plan for their website, and all of our files are stored in a datacenter. For example, my blog data are stored in the North America Datacenter of Royalclouds. If any users want to access my website, then the request will be sent to my blogs’ datacenter in North America, and then my blog will load on the user’s device.

And this is the actual cause of slow website loading, including other primary website causes.

How Content Delivery Network (CDN) Works?

CDN has its data center around different geographical locations. When a website uses Content Delivery Network, and if a user opens the website, the user can access your website like images, from the nearest data center of the CDN network.

This reduces ping and simultaneously reducing website loading speed. Now by using any CDN network, your website will load faster than before.

CDN is a kind of content replication method where your website data is copied to different geographical locations on different servers. Below is the map representation of the CDN data server around the globe.

If you guys are using any dedicated VPS Hosting, you know how high are the hosting charges. But by using the Content Delivery Network, you can quickly low down your hosting cost. All of your website data will be coming from CDN data servers, so it will dramatically reduce your hosting bandwidth charges.

3. Handle High Traffic

Whenever your site receives high traffic, sometimes your hosting might throw an “internal server error” or “database error” to your website visitors. So to get rid of it, CDN is recommended as it can handle that huge traffic and minimize website downtime issues.
