It is typical for video streaming service providers (such as NetFlix) to rely on services from cloud providers (such as Amazon), in order to build a scalable video streaming platform with high availability. The trend is largely driven by the fact that cloud providers deploy a number of datacenters inter-connected by high-capacity links, spanning different geographical regions. Video traffic across datacenters, such as video replication and transit server-to-customer video serving, constitutes a large portion of a cloud provider's inter-datacenter traffic. Charged by ISPs, such inter-datacenter video traffic incurs substantial operational costs to a cloud provider.
