Cloud Front is a content delivery network (CDN) service provided and managed by AWS.
The Amazon CloudFront consists of many nodes in the network which are called Edge Locations that are dispersed across the globe.
To reduce latency, the content is copied to all the edge locations that are located all over the world at various places.
A client, instead of making a request to original server for a file, the request will be sent to nearest edge location and it will be served from there itself.
If a client requests for a file for the first time to original server, then it is served from original server and that file is copied to all the edge locations by aws cloud front. Next time, if any client requests for that same file, it will be served from nearest edge location.
If users need to upload files to S3 buckets, then they can upload to edge locations (nearest one) thereby reducing latency and those files will be transferred to S3 much faster. AWS Cloud Front will take care of this fast transfer. This is called “S3 Transfer Acceleration”
