What is a key benefit of virtualized servers?

The key benefit of virtualized servers being a shared hardware approach highlights a fundamental aspect of virtualization technology. By allowing multiple virtual servers to run on a single physical server, it optimizes the use of resources, such as CPU, memory, and storage. This sharing enables organizations to reduce hardware costs, as fewer physical machines are needed to support the same or greater number of workloads. Additionally, it leads to better resource allocation, higher utilization rates, and improved efficiency in managing IT infrastructure.

In contrast, having individual hardware per virtual server would negate the advantages of virtualization, as it would lead to underutilization of resources and increased costs. The statement about physical servers taking less room space than virtual servers misunderstands the nature of virtual servers since they are essentially software constructs that do not physically occupy space but rely on physical hosts. Lastly, saying that virtual servers take less disk space than physical servers simplifies the discussion because it pertains more to how the underlying storage is managed rather than just the virtual environment itself. Virtual servers can require disk space for their images, which can sometimes equate to more space than traditional setups, depending on the implementation and the storage technologies used. Thus, sharing hardware stands out as the most coherent and impactful benefit of virtualization.
