What is a CDN and do I need it?

What is a CDN?

A CDN (Content Delivery Network) is a system of distributed servers that deliver web content to users based on their geographic location. This allows for faster and more efficient delivery of content, as the server closest to the user is automatically selected to deliver the content. CDNs also provide caching and other optimization techniques to improve the performance and reliability of web content delivery.

Does my site need global delivery?

CDN usage depends on your website's needs and goals. A CDN (Content Delivery Network) can improve the performance and speed of your website by serving static content (such as images, CSS and JavaScript) from multiple locations around the world. This can help to reduce latency and improve the user experience for visitors who are far from your website's primary server location.

If your website receives a high volume of traffic from multiple regions, has a large amount of static content, or needs to provide a smooth and fast user experience, then a CDN most likely would be beneficial.

However, if your website has a low volume of traffic or serves mostly localized traffic, then a CDN may be optional. It is always a good idea to assess your website's specific needs and goals before deciding whether or not to use a CDN; however, in most cases you will see additional benefit from it!
