OAS offers all options in Cloud Deliver services. Not only is the organization a certified Azure provider, OAS is also qualified in offering AWS CloudFront solutions.

When a user requests content that is served with CloudFront, the request is routed to the edge location that provides the lowest latency (time delay), so that content is delivered with the best possible performance. 

  • If the content is already in the edge location with the lowest latency, CloudFront delivers it immediately. 
  • If the content is not in that edge location, CloudFront retrieves it from an origin that has been pre-defined—such as an Amazon S3 bucket, a Media Package channel, or an HTTP server (for example, a web server) that has been identified as the source for the definitive version of the content.

As an example, when serving an image from a traditional web server, not from CloudFront, the image, for example, could serve an image, sunsetphoto.png, using the URL http://example.com/sunsetphoto.png

Users can easily navigate to this URL and see the image. But they probably don't know that their request is routed from one network to another—through the complex collection of interconnected networks that comprise the internet—until the image is found. 

CloudFront speeds up the distribution of the content by routing each user request through the AWS backbone network to the edge location that can best serve the content. Typically, this is a CloudFront edge server that provides the fastest delivery to the viewer. 

Using the AWS network dramatically reduces the number of networks that users' requests must pass through, which improves performance. Users get lower latency—the time it takes to load the first byte of the file—and higher data transfer rates. 

In addition, CloudFront does increase reliability and availability because copies of the files (also known as objects) are now held (or cached) in multiple edge locations around the world.
