Abstract:

Energy-conscious bare-metal provisioning has become an important research question since virtualized data centers are now full of mixed workloads, whose performance, isolation, and energy usage vary radically across virtual machines, containers, and direct hardware allocation. Traditional consolidation-based resource management assumes that more virtualization and higher resource utilization will always improve efficiency; however, more recent work shows this does not hold when boot latency, migration overhead, thermal characteristics, I/O interference, and workload heterogeneity are factored in. This paper reviews the current state of research on this topic in energy-aware bare-metal provisioning in virtualized data-centers and has a special focus on provisioning delay, architecture choice, power-aware scheduling, placement optimization, thermal interrelations and hybrid orchestration between bare-metal and virtualized resources. Key topics include energy modeling, dynamic resource consolidation, VM placement, bare metal reservation, hybrid resource management, and the activation-energy trade-off. Reported research suggests that energy efficiency depends heavily on server utilization, provisioning granularity, interference sensitivity, data center wide orchestration policies, and the ability to reserve non-virtualized nodes for latency-sensitive workloads.
