Server Virtualization is the practice of decoupling physical server hardware from the operating systems and applications that run on them. By employing a hypervisor, IT professionals can create and manage multiple, isolated virtual machines (VMs) on a single physical host, enabling more efficient utilization of CPU, memory, and storage. This competency encompasses the design, configuration, and maintenance of virtualized environments, including the management of host architecture, virtual hardware allocation, resource scheduling, and high-availability clusters. Practitioners in this space focus on the operational lifecycle of virtual workloads, addressing requirements such as live migration, snapshotting, and the configuration of virtual networking and storage backends. Unlike broader cloud orchestration, this skill is specifically grounded in the hypervisor layer and the foundational components required to deliver stable, isolated computing environments within an on-premises data center or hybrid infrastructure.
Server virtualization is the technical method of using a hypervisor to slice, encapsulate, and present physical server compute resources as independent, isolated virtual machine instances, allowing multiple guest operating systems to share the underlying hardware efficiently.
