What is a key benefit of decoupling virtual machines from physical hardware?

The key benefit of decoupling virtual machines from physical hardware is the enhanced resource consolidation it enables. When virtual machines are not tied to specific physical hardware, it allows for multiple VMs to run on a single physical server, optimizing the use of resources such as CPU, memory, and storage. This consolidation leads to better overall efficiency, reduced hardware requirements, and a more flexible environment in which resources can be allocated based on demand. This flexibility allows for quick scaling up or down of resources, improves energy efficiency, and minimizes hardware costs over time as fewer physical servers are necessary to support the same number of workloads.

This approach also makes it easier to manage and maintain the environment, as VMs can be migrated between hosts with minimal downtime, further enhancing operational efficiency and agility. In contrast, options suggesting increased hardware dependency, reduced operational capabilities, and increased hardware costs do not align with the benefits of virtualization and resource management provided by decoupling VMs from physical servers.
