Power model for virtual machine in cloud computing
Satit Chinprasertsuk, Sethavidh Gertphol · 2014
Cloud computing has potentials to reduce energy consumption cost for the providers by intelligently allocating virtual machines to energy efficient servers. This paper proposes a new method to create an energy model that describes a direct relationship between resource utilization in the VM and the energy consumption by the host. With the model it is possible to estimate how much energy a server will consume if it accommodates a specific number of VMs, each with a specific resource utilization. This work also investigated the power consumption of a server when different combinations of VMs with different utilization are running on it. The result shows that the energy consumption varies non-linearly with the number of VMs allocated on that host.
