نبذة مختصرة : International audience ; Cloud data centers nowadays represent a significant share of global electricity consumption and have multiple environmental impacts as Greenhouse Gases (GHG) emissions or Abiotic resources Depletion (ADP). This assessment is reinforced by the fact that, due to their overprovisioning capacities, Cloud infrastructures tend to be oversized, which results in low average resource usage and potential resources waste. The scientific literature explored multiple methods to improve resource usage and reduce energy consumption on these Cloud infrastructures. Virtual machines (VM) consolidation has been studied alongside other techniques like shutdown policies to mitigate the power consumption of infrastructures, but they are still rarely used in production in small and large-scale environments. In this poster, we revisit the potential of VM consolidation on heterogeneous cloud infrastructures. We explore a versatile consolidation methodology to reduce the energy and resources consumption of both small and large-scale virtualization infrastructures through an evaluation made on two Cloud providers. The results show that both cloud resources and energy usage can be reduced on production infrastructures.
