Why should I use a Content Delivery Network or CDN?

There are some very good reasons for using a Content Delivery Network or CDN on your site. The key ones are:

User Experience: If your site loads faster for your site’s visitors, then it is more likely that they will stay on the site and also come back for other visits.

Reduce Server Load: Having your content cached not on the edge not only makes your site faster, it also reduces the amount of load on your server for those resources and the amount of bandwidth you have to pay for.

Reduce Latency: If your server is located in the United States, but your visitors are also coming from places like Europe or Asia, it will take longer for the site to load going directly to your server for those visitors. Having the static content cached and delivered from a node closer to them will greatly reduce any latency they experience.

Traffic surges or spikes:
If you suddenly have a great crush of traffic to your site because of a major news or online event, your server may not be able to cope with the additional visitors hitting the site and may go down. Having a CDN in front of the site will greatly reduce the probability that your site will go down.
