Why CDN is Important for Your WordPress Blog?3 min read

CDN is something that is used before having a hosting account as it speeds up certain things. However, it is not an alternative to a hosting account. You may still want to have a hosting account from a hosting provider like Siteground etc.

What is CDN?

CDN refers to Content Delivery Network, a server network which delivers cached website content to the users as per the user’s geographic location. Seems confusing, isn’t? Let’s break things down in easier words.

Basically, when a user enters your WordPress blog, they are directed to the server of your web host like HostGator.

The server location of your web host may be Houston, Texas or any central location. So, every user is accessing that server to see your website’s content. If you receive huge volume of traffic, the server is overloaded which causes your site to load slowly or server is crashed.

This is where CDN saves you from trouble. It is a network of servers. Basically these servers are located across the world. By using CDN, the static content is cached and saved on all those servers. Static content features images, JavaScript, stylesheets (CSS files), Flash etc. When someone enters your original server or site, CDN redirects them to the nearest server to their area.

For instance, if main server is located at Houston, TX, and visitor from Durham, England wants to access it, they will be connected to nearest server in London. It controls the internet hops required to transfer the static files to the user.

Switching to a new WordPress theme? Consider these top five things.

The proximity of your user to the web server affects load time. So, you can deploy your content to several servers across the world to make your webpage loading faster from the user’s end. This is when CDN works. Simply speaking, the closer the CDN, the faster the user accesses the content.
