Recommendation : 3. Adapt the use of technical equipment to needs
Is the size of the physical park in line with the number of virtual machines to be run ?
Is the allocation of physical resources relative to virtual machines monitored?
Virtualization techniques make it possible to pool the physical resources of a server and a storage space. This abstraction can optimize the use of equipment, but can also lead to underutilization of physical equipment and to a deployment of new equipment before the need is really present. The total environmental footprint of a server and its use is significant.

Rule for assessing the level of compliance of the criterion
Taux utilisation VM > 60 = 100 ; 60-40 = 50 ; < 40 = 0 / 100
11 other criteria related to the recommendation: Adapt the use of technical equipment to needs
Are servers / routers turned off when not in use ?
Is the allocated memory based on actual use ?
Is the number of CPU cores allocated based on actual use ?
Is the technical choice (shared, dedicated, clustered) optimised between the actual need and energy efficiency ?
Are unused cores disabled ?
Is the backup system incremental (disk optimization) ?
Is the use of containers over virtual machines preferred ?
Are Open Source solutions implemented when available ?
Is high availability designed in a modular fashion ?
Is provisioning / deprovisionning dynamic depending on the load ?
Do storage solutions reduce the number of components (for example: high density SSD media) ?
