MILENA: a model for implementing distributed multiplayer games in computing clouds

Cloud computing environments are characteristically composed of distributed infrastructure, heterogeneous and virtualized resources, besides serving concurrently a wide range of customers whose service level agreements may require different levels of Quality of Service (QoS). Distributed multiplayer games, in turn, are collaborative distributed applications that must have an acceptable level of QoS to maintain justice among its players. This article proposes MILENA, a model for implementing distributed multiplayer games on computer clouds. The proposed model meets the requirements of QoS, fault tolerance and scalability. As a case study for verification and validation of the proposal, we have developed a game and evaluated its performance by SLA violations and response time of requests metrics. The results show that the MILENA scales up to 100 players without QoS loss, thus improving justice in distributed multiplayer games.
