On the impact of advance reservations for energy-aware provisioning of bare-metal cloud resources
Marcos Dias de Assuncoo, Laurent Lefèvre, François Rossigneux · 2016
This work investigates factors that can impact the elasticity of bare-metal resources. We analyse data from a real bare-metal deployment system to build a deployment time model, which is used to evaluate how provisioning time impacts the reservation of bare-metal resources. Climate/Blazar, a reservation framework designed for OpenStack, is discussed. Simulation results show that reservations can help reduce the time to deliver a provisioned cluster to its customer while achieving energy savings similar to those of strategies that switch-off idle resources.
