Also written as Content Delivery Network, CloudFront
A network of geographically distributed servers that cache and serve content (images, videos, static files) from a location physically close to each user, reducing load times.
Think of it like
Like a chain of regional warehouses, so a customer's order ships from the nearest one instead of every single order coming from one central factory across the country.
