Precisions

The management of the consumption of physical resources involves data collection of the physical equipment and of all the virtual equipment it hosts. Recent virtualization techniques allow parameters to be changed without interruption to increase or decrease the resources (CPU / RAM) allocated to virtual machines, as needed, or even migrate virtual machines to less loaded physical servers.
