QoS-Aware, Cost-Efficient Selection of Cloud Data Centers

Cloud computing is increasingly used to deliver multimedia services with stringent Quality of Service (QoS) requirements, rather than simple infrastructure. Due to these requirements, the QoS-aware, cost-efficient selection of data centers arises as a new research challenge. In our ongoing work, we examine the corresponding Cloud Data Center Selection Problem and propose an exact optimization approach. A brief evaluation indicates that the proposed approach is primarily suited for small problem instances due to its high computational complexity, and hence highlights the need for the development of heuristic optimization approaches.
