Public and private clouds based on VMs are a modern approach for deploying computing resources. Virtualisation of computer hardware allows additional optimizations in the utilisation of computing resources compared to the traditional HW deployment model. A price to pay when running virtual machines on physical hypervisors is an additional overhead. This is an area of concern in the context of...
