Pay-as-you-use on-demand cloud service: An IPTV case

Cloud computing, the latest buzzwords in the technology sector, describes a new era of Internet usage when services are delivered over the Web. The present work proposes a new strategy to integrate cloud solutions to curb the rising IT costs, the complexity of network management, and infrastructure inefficiencies for IPTV. This new approach adopts two virtualization techniques: 1) server virtualization - virtual servers co-reside on a single dedicated server, and 2) application virtualization - the customer select to play a channel or videos from program menu. In these cases, all videos behave as if they are being streamed by a dedicated server. An architectural framework, named the Video-on-demand as a Service (VoDaaS), which formalizes the contextualization of the on-demand cloud service for IPTV, enabling subscribers to receive television programs or video stream from anywhere, is proposed. We highlighted the components of the framework and discussed preliminary implementation in the paper.
