A CDN (Content Delivery Network) is a distributed server infrastructure that helps deliver web content to visitors on your website. Instead of loading the content from a single server, it is spread across multiple servers around the world. Using a CDN is usually only worthwhile if the visitors are spread over a larger geographical area.
The primary purpose of a CDN is to improve page speed and performance through reduced latency and shorter response times. When someone visits your website, their request will automatically be routed to the nearest server in the CDN network, resulting in a faster experience for the user regardless of their geographic location.
In addition to increasing speed, a CDN can also handle large amounts of traffic and distribute the load evenly across the servers. This means that your website will not be overloaded in case of high traffic volume or DDoS attacks, which contributes to better operational security.
Depending on the type of content you have on your website and where in the world your primary visitors are located, a CDN may be worth investing in. A prerequisite for CND to be helpful is often that the website's primary visitors are scattered all over the world. Additionally, if you have heavy multimedia files or a lot of images, it can definitely help you reduce download times and optimize your web content globally.
In conclusion, if you want faster page speed, better performance, scalability and security, and the ability to deliver your content globally, you should definitely consider using a CDN for your website. But using a CDN for a website that only has visitors in Sweden does not give as great an effect as if the visitors were scattered all over the world.
