Description: The host refers to a physical machine that runs one or more virtual machines. In the context of virtualization, the host provides the necessary hardware resources, such as CPU, memory, and storage, for the virtual machines (VMs) to operate efficiently. Each virtual machine operates as an independent system, with its own operating system and applications, while sharing the same underlying hardware. This architecture allows for better resource utilization, as multiple environments can coexist on a single physical server. Additionally, the host can manage resource allocation, security, and isolation between different virtual machines, which is crucial in cloud and enterprise computing environments. The ability to scale and manage multiple VMs from a single host is fundamental for cost optimization and operational efficiency in modern IT infrastructure.
