Overview of Distributions

https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/distribution-overview.html

When you want to use CloudFront to distribute your content, you create a distribution and choose the configuration settings you want. For example:

CloudFront Configuration Settings

• Your content origin—the Amazon S3 bucket, MediaPackage channel, or HTTP server from which CloudFront gets the files to distribute. You can specify any combination of up to 25 Amazon S3 buckets, channels, and/or HTTP servers as your origins.
• Access—whether you want the files to be available to everyone or restrict access to some users.
• Security—whether you want CloudFront to require users to use HTTPS to access your content.
• Cookie or query-string forwarding—whether you want CloudFront to forward cookies or query strings to your origin.
• Geo-restrictions—whether you want CloudFront to prevent users in selected countries from accessing your content.
• Access logs—whether you want CloudFront to create access logs that show viewer activity.

For the current limit on the number of distributions that you can create for each AWS account, see General Quotas on Web Distributions. The number of files that you can serve per distribution is unlimited.

Type of Content a Distribution can Server

• Static and dynamic download content
• Video on demand in different formats
• A live event, such as a meeting, conference, or concert, in real time
