An advantage of virtualizing servers, databases, and office applications is:

Virtualization platforms such as VMware vCenter or Microsoft Hyper-V Manager allow administrators to provision, monitor, and control all virtual machines from a single interface. This reduces administrative overhead and improves consistency across the environment. Centralized management is the defining operational benefit that distinguishes virtualized infrastructure from managing disparate physical hardware.

Virtualization shares existing physical resources among VMs rather than providing greater total resources to any individual user.

Virtualization does not inherently strengthen access control; access control mechanisms must be separately designed and enforced regardless of the hosting model.

Virtualization consolidates management onto a single platform, which is the opposite of decentralization.
