Many researchers, both in academia and industry, are very interested in MMOGs. MMOG environments require a high degree of flexibility to respond to environmental changes, including load change. We combine cloud computing with MMOGs to increase flexibility of resource allocation. In an MMOG cloud environment, we use virtual machines (VMs), instead of traditional physical game servers. A game world is divided into several game regions. Each game region is serviced by at least one VM. However, in the multi-server architecture, loads of regional servers may be unbalanced because there may be some regions that attract more players. Peer-to-peer (P2P) cloud computing is a new approach that combines high computation power, scalability, reliability and efficient information sharing of servers. This paper proposes a hybrid P2P cloud architecture for MMOGs which includes two-level load management, multi-threshold load management for each game server and load management among game servers. It is suitable for players to interact with P2P cloud servers and it avoids bottlenecks of the current multi-server MMOG architecture. Simulation results show that the proposed architecture can support 10.31% more players under no deadline (300 ms) miss compared to the multi-server architecture. The proposed hybrid P2P cloud architecture can reduce the average response time by 20.6% composed to the multi-server architecture under medium to high load through flexible allocation of resources (virtual machines). The proposed architecture also has a 27.9% smaller deadline miss ratio than the multi-server architecture under medium to high load.
