CDN
(Content Delivery Network)
A network that keeps copies of website content close to users so it loads faster
What's it for?
Makes websites and downloads faster by keeping copies of common content closer to users.
For example…
Staff in Manchester download the training video from a nearby CDN cache instead of pulling it from a distant origin every time.
A news site uses a CDN so readers in different countries download images and scripts from a nearby location instead of one distant server
Think of it like…
Having local depots that keep copies of items closer to customers, so they don’t all have to come from one distant warehouse
