What is one of the main benefits of using virtualization in IT?

One of the main benefits of using virtualization in IT is that it allows for better resource allocation. Virtualization enables multiple virtual machines to run on a single physical server, which maximizes the utilization of hardware resources. This leads to more effective use of CPU, memory, and storage, as tasks can be allocated dynamically based on current needs. By optimizing resource usage, organizations can reduce waste, lower operational costs, and improve overall efficiency.

In contrast to this, increasing hardware costs is contrary to the principle of virtualization, which typically aims to consolidate workloads and reduce the need for additional physical servers. While virtualization does simplify network management to some extent, the core advantage lies more in the efficient use of resources. Enhancing physical security is not a primary feature of virtualization; rather, it focuses on logical separation and management of resources rather than the physical security of the hardware itself.
