Approximate Co-Location-Resistant VM Placement Strategy With Low Energy Consumption

Abstract

In cloud computing, muti-tenancy enables virtual machines to co-host the same server to reduce the power expenses. Although, there may exist co-hosts that attempt to conduct co-location attacks, which cause data leakage. To address this challenge, the most recent works present Virtual machines placement strategies minimizing co-location attacks and energy consumption. Few works establish a security before-hand threshold to constraint attack probability with respect to the provider/users priorities. Thus, we adopt this approach and introduce a novel virtual machines allocation strategy that considerably reduces energy consumption. Finally, we deploy our strategy and prove its high performance on the simulation platform CloudSim.
