What is a common use case for virtualizing servers?

Virtualizing servers is commonly used to reduce physical space and energy consumption. By using virtualization technology, multiple virtual machines can run on a single physical server. This consolidation minimizes the number of physical servers needed, which in turn decreases the overall physical footprint in a data center. With fewer physical machines, the required space for hardware is significantly less, leading to lower real estate costs.

Additionally, energy consumption is reduced because fewer servers mean less power required for processing and cooling the hardware. This reduction in physical resources is also beneficial from an environmental standpoint, as it contributes to energy efficiency initiatives.

While other choices may reflect some aspects relevant to server virtualization, they do not encompass as broad a benefit or priority as the reduction in space and energy consumption, which is a primary reason organizations adopt server virtualization strategies.
