Distribution
A CloudFront distribution is a globally distributed network of caching servers. These servers are used to serve content to end-users with low latency and high data transfer speeds. Distributions have unique domain names or alternate domain names that identify them. AWS customers can create multiple distributions associated with their AWS account, each serving different types of content or use cases. Users can choose from two types of distributions, web distributions for serving static and dynamic content, and RTMP (Real-Time Messaging Protocol) distributions for serving streaming media.
