Energy Models for Virtual Machines
Research Guide
What is Energy Models for Virtual Machines?
Energy models for virtual machines are computational frameworks that predict and optimize power consumption of VMs in cloud and cluster environments through measurement-based and migration-aware techniques.
Research develops models like computation type power models (Enokido and Takizawa, 2015, 36 citations) and group migration algorithms (Duolikun et al., 2019, 21 citations). These address energy waste in virtualized infrastructures. Over 10 papers from 2011-2022 focus on VM energy prediction and reduction.
Why It Matters
VM energy models enable precise resource allocation in data centers, cutting operational costs and carbon emissions in cloud systems handling 70% of enterprise workloads. Enokido and Takizawa (2015) model VM power for scalable services, reducing energy by 20-30% via load balancing. Duolikun et al. (2019) show static/dynamic VM migrations save up to 15% energy in server clusters, directly impacting hyperscale providers like AWS.
Key Research Challenges
Accurate Power Prediction
VM power varies with workload types, making static models inaccurate for dynamic clouds. Enokido and Takizawa (2015) propose computation models but note 10-20% prediction errors. Measurement-based calibration remains hardware-specific.
Migration Energy Overhead
VM migrations consume extra energy during transfer, offsetting consolidation gains. Watanabe et al. (2016) model eco-migration but highlight laxity-based limits (15 citations). Balancing live migration costs with long-term savings is unsolved.
Scalability in Large Clusters
Models scale poorly to thousands of VMs due to inter-VM interference. Duolikun et al. (2019) address group migrations but computational complexity grows quadratically. Real-time optimization for fog/cloud hybrids lacks efficient algorithms.
