Optimization of resource reconfiguration for cloud-based multimedia applications

The cloud-based multimedia applications have been increasingly adopted in recent years. The key challenge for the application providers is how to optimally reconfigure resources to cope with the time-varying workload. In this paper, we study the optimal resource reconfiguration for cloud-based multimedia applications to minimize the average round-trip-time (RTT). Specifically, we propose the optimal resource reconfiguration schemes for single-site cloud and multi-site cloud, respectively. In each case, we formulate and solve the average RTT minimization problem. Simulation results demonstrate that the proposed optimal resource reconfiguration schemes can optimally utilize cloud resources to achieve the minimal average RTT.
