QoS architecture for cloud-based media computing

Cloud computing is the current significant technology trend because of its potential to reduce the cost and increase the productivity. Virtualization is the key enabling technology in cloud computing which maximizes the utilizations of resources to provide the service. Multimedia application over cloud computing has its quality of service (QoS) requirements such as bandwidth and delay. The provision of QoS is challenging in cloud computing environment because of the virtual platforms. This paper proposed an architecture of private cloud for media computing. It addresses the QoS provision mechanisms at the virtualized infrastructure. The paper also presents an example of a low-cost virtualized video streaming server on VMware.
