Resources allocation trade-off between cost and delay over a distributed Cloud infrastructure

Massively Multiplayer Online Games (MMOG) keep attracting hundreds of thousands of players from all over the world. Ensuring a scalable and latency-sensitive MMOG service is a challenge task since it is subject of high workload variability. Traditionally, MMOG providers used to over provision resources in order to cope with worst workload scenario. Nowadays, MMOG infrastructures have switched to Cloud computing paradigm. In this paper, we propose a novel architecture for MMOGs and we address the problem of dynamic resources provisioning over a distributed cloud infrastructure. Our contribution allocates necessary virtual resources while managing the trade-off between resource allocation cost and processing delay constraint. Experiment results prove effectiveness of our proposition.
