An energy aware framework for virtual machine placement in cloud federated data centres

  1. 1. An Energy Aware Framework for Virtual Machine Placement in Cloud Federated Data Centres Corentin Dupont Authors: Corentin Dupont (Create-Net); Giovanni Giuliani (HP Italy); Fabien Hermenier (INRIA); Thomas Schulze (Uni Mannheim); Andrey Somov (Create-Net)
  2. 2. Presentation ü FIT4Green seeks energy saving policies for DCs, enhancing the effects inside a federation by an aggressive strategy for reducing the energy consumption in ICT ü We aim at reducing cost for companies è Strengthening competitive position ü FIT4Green needs to be DC framework agnostic: § Demonstrated in Cloud computing, Traditional computing, Super computing and Networking
