VIRTUALIZATION Meaning and
Definition
-
Virtualization refers to the process of creating a virtual version or representation of a physical entity, such as a computer, operating system, or even a network infrastructure. It involves the creation of a virtual environment that simulates the functions and capabilities of the physical entity.
In the context of computing, virtualization primarily pertains to the creation of virtual machines (VMs). A virtual machine is an emulated computer system that operates in a self-contained environment within a physical machine. Multiple VMs can coexist on a single physical machine, each running its own guest operating system and applications, independent of one another.
The main purpose of virtualization is to maximize the utilization of hardware resources and enhance flexibility in managing and deploying software applications. It allows the consolidation of multiple servers or machines into a single physical unit, leading to cost savings in terms of power consumption, maintenance, and space requirements. Moreover, virtualization enables easier and faster software deployment, testing, and disaster recovery.
Virtualization can also extend to other areas, such as network virtualization, storage virtualization, and application virtualization. Network virtualization creates virtual networks that are logically separated from the physical network infrastructure, allowing for increased flexibility and scalability. Storage virtualization abstracts physical storage devices and presents them as virtual storage pools, simplifying management and improving efficiency. Application virtualization isolates applications from the underlying hardware or operating system, enabling them to run in a self-contained environment without conflicts.
Overall, virtualization provides a framework for creating virtual instances that mimic physical systems, thereby delivering greater efficiency, flexibility, and agility in the realm of computing and networking.
Common Misspellings for VIRTUALIZATION
Etymology of VIRTUALIZATION
The word "virtualization" has its roots in the Latin word "virtus", meaning "virtue" or "power". In the 15th century, the term "virtual" was introduced to refer to something having the essence or effect of a particular quality or thing though not physically existing. In the context of technology, "virtualization" was coined in the late 1960s to describe the process of creating a virtual (rather than physical) version of something, such as an operating system, network, or storage device. It involves abstracting and isolating resources, allowing them to be shared and utilized more efficiently.
