Working with AWS Elemental MediaPackage and CDNs

You can use a content delivery network (CDN) such as Amazon CloudFront to serve the content that you store in AWS Elemental MediaPackage. A CDN is a globally distributed set of servers that caches content such as videos. When a user requests your content, the CDN routes the request to the edge location that provides the lowest latency. If your content is already cached in that edge location, the CDN delivers it immediately. If your content is not currently in that edge location, the CDN retrieves it from your origin (in this case, the MediaPackage endpoint) and distributes it to the user. The following illustration shows this process.

The following sections provide more information about using a CDN in your MediaPackage workflow.
