What is a CDN and why do you need one?

A CDN, or content delivery network, is a system of servers distributed around the world that are used to store copies of static files (such as JavaScript, CSS and HTML files) and deliver them to users locally regardless of their location.

This can be useful for several reasons. First, it can help reduce the load on your own server, since your files are stored on other servers.

Second, it can help speed up the delivery of those files to users, since they can be retrieved from a nearby server location instead of one from far away.

And finally, it can help improve the security of your website by routing your traffic through an eternal firewall, making it harder for hackers to access your server directly.

How do you choose the right CDN for your website?

The first step is to identify your content delivery needs:

• Do you need to deliver static text, images and videos or pages that are dynamically built?
• How about managing low, medium or high amounts of traffic?
• Do users need to access your site from around the globe or are they local in relation to your website's server?

Once you know what your needs are, you can begin to evaluate different CDN providers.

Some factors to consider when choosing a provider include:

• Capabilities: Make sure the CDN provider offers the features that you need, no more and no less, so you don't end up paying for bells and whistles that don't apply to your circumstances
• Global Coverage: Choose a CDN provider with servers located in regions where your users are located. There's no point in paying extra for a vast distributed network in areas of the world where your users don't live
• Price: Compare pricing plans from different providers and choose one that fits your budget, but don't skimp on speed or uptime. The lack of either can result in search engine penalties
• Customer Support: Finally, choose a CDN provider with 24/7 customer support, preferably live support
  

What to Do Next

Nowadays, a CDN is an essential component for any website that wants to load fast from anywhere around the world.

By caching your files on multiple globally distributed servers, visitors from all corners of the world will experience faster speeds and as a result your site will rank higher on search results.

So, if you're looking to turbocharge your website, be sure to consider a CDN as one of your top priorities. Most of the above networks offer either free trials or a money back guarantee.
