What does server virtualization involve?

Server virtualization primarily involves the logical partitioning of a physical server into multiple virtual servers, allowing for the efficient use of resources and improved management. This process enables a single server to run multiple operating systems and applications independently, as if they were running on separate physical machines. By abstracting the physical hardware, virtualization optimizes resource utilization, enhances performance, and simplifies server management.

In the context of the given choices, logical partitioning is fundamental to allowing multiple virtual systems to coexist on one piece of hardware. This contrasts with other options that do not accurately describe the core function of virtualization. For instance, physical concealment of data relates more to data protection strategies rather than virtualization principles. Similarly, the mere installation of multiple operating systems on one server doesn’t encompass the complete essence of virtualization, which focuses on the abstraction and isolation features facilitated by a hypervisor. Lastly, creating physical copies of servers is associated more with data redundancy and backup strategies than with virtualization itself.
