Overview of Download and Streaming Distributions

Note

By default, you can create a combined total of 100 download and streaming distributions for each AWS account. To request a higher limit, go to http://aws.amazon.com/cloudfront-request/.

The number of files that you can serve per distribution is unlimited.

Download distributions serve both static and dynamic content, for example, .html, .css, .php, and image files, using HTTP or HTTPS. A download distribution gets files from locations—known as origins—that you specify. Each origin is either an Amazon S3 bucket or an HTTP server, for example, a web server. You can specify any combination of up to 10 Amazon S3 buckets and/or HTTP servers as your origins.

For more information about how download distributions work, including the values that you specify when you create a download distribution, see Working with Download Distributions. For information about creating a download distribution, see Creating Download Distributions.

Streaming distributions stream media files using the Adobe Real-Time Messaging Protocol (RTMP). A streaming distribution must use an Amazon S3 bucket as the origin.
