Submission summary

Companies are increasingly outsourcing their IT to cloud as a result of the attractive prices generated by resource pooling. Virtualization is used in the cloud to isolate applications, each being executed in a virtual machine (VM), which may be seen as an operating system (OS) with a limited amount of allocated resources. Power consumption is a major concern in the cloud (50-70% of the investment). VM consolidation, the most important mean for reducing the power consumption, is limited by virtualization which can run a VM exclusively on a single physical machine (PM). The latter must have enough available resources. This constraint leads to datacenter fragmentation, hardly addressable by consolidation considering the incongruous sizes of VMs. Because of these limitations, we have observed a significant level of resource waste in a cluster of our cloud partner (Eolas - Grenoble, France). The Scalevisor project proposes a virtualization that meets the nowadays cloud requirements: that is the unification of the ressourcesof several PMs into a single powerful PM. We propose to do this at the granularity of a rack where fast network links (Infiniband) are used.
