This illustration is centered on the Amazon cloud, which is depicted here as a cloud shape containing five servers. Three arrows point from the Amazon cloud towards three servers, each labeled "CDN server;" the arrows are labeled "Upload version to CDNs." Below the Amazon cloud is a desktop computer, labeled "Client," representing the user of Netlflix's service. A blue arrow, labeled "Manifest file," points downward from the cloud to the client. Another arrow, labeled "Video chunks (DASH)," also points from one of the CDN servers to the Client.
