Towards bringing real-time online applications on Clouds

The paper studies an emerging class of Real-Time Online Interactive Applications (ROIA), including multi-player online computer games, e-learning and training applications based on real-time simulations, etc. ROIA combine the challenge of the scalability and real-time user interactivity with the problem of efficient and economic utilization of resources for changing number of users. To address these challenges, we develop a dynamic resource management system which implements load balancing for ROIA on Clouds. We illustrate three different load-balancing actions and report experimental results on bringing a multi-player online game on Cloud.
