Content Delivery Network: Good Choice For Your Website

Should you purchase a Content Delivery Network (CDN) for your website? If you have an online store or a high-traffic website is a good choice to invest in a CDN. Besides improving the speed of your website, this service can also protect your website against Distributed Denial of Service attacks and improve your SEO rankings.

What Is A Content Delivery Network?

This network is a group of servers placed all around the world which work together to provide websites and other Internet content to visitors faster. Since these servers are all over the world, visitors from different countries can view your website, and all of its files, with little wait.

If you didn’t have a CDN only the visitors living in the country where your server resides would get fast delivery speeds. For example: I’m American and my web hosting uses servers in America to host my websites. Thus, any American visitor to my sites would get the fastest traffic. Other visitors from around the globe would get decent to slow loading times, depending how far away they are from the servers.

Note: A CDN isn’t a replacement for web hosting. You still a web hosting package to host your website; the CDN will work with your hosting to cache your content. Caching in this sense means taking a copy of your website and placing it on different servers so visitors can view it quicker. Without caching, visitor would have to get the content from your web host. And if there’s too many visitors trying to access your website at once then performance will suffer.

Reason #1 Why A Content Delivery Network Is A Good Choice: Faster Loading Speeds

The first reason why you should invest in a Content Delivery Network because this service can improve your website’s loading speeds. Why? Due to all the servers in placed around the world. Major CDN companies have servers spread out on all continents. Hence, the faster loading times. It doesn’t matter if your visitors are in the middle of Africa or up on Norway. And remember that caching I discussed earlier? That’s another reason for the faster loading speeds.

Reason #2 Why A Content Delivery Network Is A Good Choice: Lower Bandwidth Costs

The second reason why you should invest in a CDN is to lower your bandwidth costs. Now, if you have a hosting package that gives you unlimited bandwidth then this tip won’t apply to you. However, if you have a VPS or a Dedicated Server then this tip will do you well. That’s because these two hosting packages charge for bandwidth when you go over a certain amount.

A CDN will help you here because of caching and other features. Thus, you don’t have to worry about paying overage fees to your web hosting company.

Final Reason: Protection Against DDoS Attacks

The final reason why you should invest in a Content Delivery Network is to get protection against Distributed Denial of Service attacks. These attacks can be pretty devastating and leave your website down for hours if not days. A CDN can prevent these attacks by mitigating it through various network devices and/or software. Usually, the service can drop the malicious traffic and only allow the “good” traffic through. This is a simplified version of what happens.
