What is a Content Delivery Network (CDN)?

A website is typically hosted on a server managed by a web hosting company. The public will visit the website from their computer’s browser and the website will be served from the hosted server. This raises a few concerns though. Website loading speed being a major concern. What happens when the hosted server goes down? Is the web hosting provider doing all they can to block attacks to the website? These are realities that website owners need to be aware of every day. A CDN could be a platform to help enhance your website hosting solution and thereby offer improved performance for your website.

A CDN is a network of servers located in many countries. When adding your website to a CDN, your visitors will access your website from the CDN server closest to them causing a faster website load time.
How can a CDN enhance your website hosting?
The first thing to note is that a CDN is not a replacement for your website hosting. You require both. What is the purpose of a CDN?

1. Improve website loading times
Your website visitors will appreciate the fast load times, obviously. Google will also pay more attention to your website if it loads quicker.

2. Ensure maximum availability of your website
The servers on the CDN will cache your website. All the scripts and media that make your website work will be stored on these servers. If your host goes down, your website will still be largely available. This excludes any content that might be dynamically served through other web services such as a live weather report or traffic updates.

3. Bolster your website security
Most popular CDN’s will include features such as SSL certificates, firewalls and DDoS protection.
