What is virtualization primarily defined as?

Virtualization is primarily defined as the creation of a virtual version of physical resources. This concept allows multiple virtual systems to run on a single physical hardware platform, enabling more efficient resource utilization and management. By using virtualization technologies, organizations can host multiple operating systems and applications on a single server, optimizing hardware usage and reducing costs associated with physical machines.

In contrast to creating an actual version of hardware, virtualization does not involve replicating physical components but rather simulating them through software. It also does not eliminate physical resources; instead, it leverages them for better efficiency. Additionally, virtualization is not about replacing all existing operating systems; rather, it provides the capability to run various operating systems simultaneously on the same physical infrastructure.
