Content Delivery Network (CDN)

Imagine someone visiting your website, and only a server is available to load it, which means you can lose visitors if the server does not respond properly. CDN stands for Content Delivery Network. Your website may take longer than usual to load. But, if you have a Content Delivery Network option enabled, then the group of distributed servers around the globe is ready to speed up your website to make a good website.

Let us see some interesting things about Content Delivery Networks. We encounter them daily by reading online newspapers, articles, watching online videos, or shopping on our favorite e-commerce websites. It does not matter what language or font the content is in that you are reading. It is about a webpage showing on the internet.

Know the importance of the Content Delivery Network, you must understand it by an example:

You switch to an e-commerce website to purchase shoes. Now, consider two possible situations. What will you do if the website takes longer than usual to load? You will switch to another website, right? If it loads in the shortest possible time, you will like to return to that website in the future. So, speed matters a lot.

In this case, the Content Delivery Network (CDN) plays its role and removes time-lagging by providing results from the nearest available data center. If an e-commerce giant like Amazon takes a little more time than it usually does, thousands of thousands of customers will leave the website immediately, which means a loss for them.

In a nutshell, CDN boosts the performance of your website by allowing it to load faster and providing cached internet content from the nearest server.

How does a CDN function?

To provide the best service to the customers, CDN acts as a bridge between them. To begin, CDN stores recent copies of cached versions of content on its nearest data center (which may have more than two data centers depending on the pack and services).In other words, a CDN distributes website content to multiple locations to provide the fastest service possible.

Consider the following example:

Assume you are sitting in New York and accessing a Europe-based hosting service for a website. When you visit the website, it does not use the European server. It will display a cached version of the website from the local data center somewhere in the USA.

So, this is a basic step in working with a CDN, or content distribution network, as it is also known.

We consider that you get an idea of its working pattern. So let’s go further —
