Towards Optimal Deployment of Cloud-Assisted Video Distribution Services
For Internet video services, the high fluctuation of user demands in geographically distributed regions results in low resource utilizations of traditional CDN systems. Due to the capability of rapid and elastic resource provisioning, cloud computing emerges as a new paradigm to reshape the model of video distribution over the Internet, in which resources (such as bandwidth, storage and etc.) can be rented on demand from cloud data centers to meet volatile user demands. However, it is challenging for a Video Service Provider (VSP) to optimally deploy its distribution infrastructure over multiple geo-distributed cloud data centers. A VSP needs to minimize the operational cost induced by the rentals of cloud resources without sacrificing user experience in all regions.
