New Features

Streaming Content With the new API version (2009-12-01), Amazon CloudFront gives you the option to stream on-demand media files over a Real-Time Messaging Protocol (RTMP) connection, or several of its variants. To do this, you use a new type of distribution called a streaming distribution. Streaming distributions are very similar to basic distributions, except they use RTMP instead of HTTP. For complete details of how to use CloudFront to stream on-demand content, go to Streaming Media Files in the Amazon CloudFront Developer Guide.
New API Version With this release, Amazon CloudFront has a new API version (2009-12-01) for the control API. The schema is at This new version is backward compatible with the previous versions (2009-04-02, 2008-06-30, and 2009-09-09). If you want to take advantage of the new streaming content feature, you must upgrade to the 2009-12-01 version.

Known Issues

No access logs or private content for streaming distributions Currently there are no access logs available for streaming distributions. Also, all content served with a streaming distribution must be publicly accessible to all end users. You currently can't restrict access to RTMP streamed content through the use of special signed URLs.
No console support for private content Currently the AWS Management Console does not let you create or update distributions with the components required to serve private content.
Range GET objects not cached If an end user sends a byte-range GET request for an object that isn't cached in the edge location, Amazon CloudFront fetches only the specified range from the origin and then serves the request. It doesn't cache either the range or the object.
