Description: A physical host is a physical server that provides the necessary resources to host and run virtual machines. This type of server acts as the foundation upon which virtualized environments are built, allowing for the creation of multiple instances of operating systems and applications on a single hardware platform. Physical hosts are essential in virtualization infrastructure, as they offer resources such as CPU, memory, storage, and networking, which are shared among virtual machines. The capacity of a physical host is measured in terms of its processing power, amount of RAM, storage capacity, and network connectivity. Additionally, physical hosts are often equipped with hypervisors, which are software that enable the management of virtual machines, facilitating resource allocation and performance monitoring. Virtualization on a physical host not only optimizes resource usage but also enhances operational efficiency, reduces costs, and provides greater flexibility in managing IT infrastructure.
