Recent research in Game Theory-based VM Placement in Cloud Computing explores strategic frameworks where cloud providers and users act as players in a game, competing or cooperating to optimize virtual machine (VM) placement across physical hosts. These approaches use models like Stackelberg and cooperative games to reflect real-world interactions: providers aim to maximise utilization, minimise energy cost, and avoid SLA violations, while users seek performance and budget advantages. By framing VM placement as a game, these studies derive equilibrium strategies for resource allocation, cost-sharing, and QoS trade-offs, enabling adaptive, fair, and energy-aware VM placement decisions in multi-tenant cloud infrastructures.
