Reducing power consumption has been an essential technique for Cloud resources and data centers not only to decrease operating costs, but also to improve the system reliability. As Cloud computing becomes emergent for Anything as a Service (XaaS) paradigm, modern real-time Cloud services are also available throughout Cloud computing. In this paper, the authors investigate power-aware provisioning of virtual machines for real-time services. Their approach is: to model a real-time service as a real-time virtual machine request; and to provision virtual machines in Cloud data centers using Dynamic Voltage Frequency Scaling (DVFS) schemes.
