What is one key benefit associated with the use of hypervisors in virtualization?

The use of hypervisors in virtualization significantly enhances scalability, which is a critical benefit. Scalability refers to the ability to grow or shrink resources as needed to accommodate varying workloads and applications. Hypervisors allow multiple virtual machines (VMs) to run on a single physical server, making it easier to add or remove VMs dynamically. This flexibility enables organizations to respond quickly to changes in demand, facilitating better resource utilization and cost efficiency.

By using hypervisors, businesses can also efficiently manage workloads across different environments, whether they're in-house data centers or cloud resources. This adaptability supports the rapid deployment of applications and services in a scalable manner, as new instances can be created with relative ease without requiring significant additional hardware investment.

In contrast, factors like increased hardware costs are contrary to the objectives of virtualization, which typically aims to maximize existing resources. Physical security and strict resource allocation are considerations in virtualization, but they do not directly relate to the core advantage of scalability that hypervisors provide.
