CloudFront from Amazon Web Services is a global content delivery network (CDN) service.

A CDN accelerates the delivery of your website by caching copies of your static content, such as images, CSS & JS files, using a network of servers around the world.

For example, if a customer is visiting your website from Europe, they will download all your website’s static content from the physically closest European server. This method decreases the load time of your website and frees up your server resources.

Affordable Content Delivery

Amazon Cloudfront is cheap CDN solution if you are a small website owner because the service is intended to be sold in bulk to large-scale websites. If you are only using a minimal amount of resources, 1 medium size website might cost lest then $1 a month to host.
