Content Delivery Networks - CDN
Service: Cloud Front
- It's Like Caching

- 450 Edge Locations currently
- Speeds up distribution of static web content, html/css/jss by using aws backbone and not internet
-

Example:
User wants to watch a movie but they are sitting very far from where the movie Is stored. The request will be routed to the nearest edge location from the 450 edge locations that we have.
The edge location checks if it has the movie in the catch, if not, it’s called a cache miss.
So if there is a cache miss at the edge location our request goes to the origin but not via the internet but via the AWS backbone.
Once the request is answered the edge location close to our user holds that movie into it’s cache so the next user that comes along to the edge front will have a much faster experience
