Why each option
Datacenter virtualization improves hardware resource utilization and standardizes the virtual hardware interface presented to VMs regardless of the underlying physical host.
Virtualization does not reduce the volume of data that must be backed up - the same application data exists and requires protection whether workloads run on physical or virtual hardware.
The hypervisor layer introduces CPU overhead, so a given application typically requires the same or slightly more CPU resources in a VM compared to running directly on bare metal.
Virtualization consolidates multiple workloads onto shared physical servers, dramatically increasing CPU, memory, and storage utilization rates compared to the traditional one-application-per-server model.
Each VM is presented with standardized virtual hardware devices (such as VMXNET3 NICs and PVSCSI controllers) regardless of which physical host it runs on, ensuring a consistent hardware footprint that simplifies driver management and enables live migration between hosts.
