Which of this is best defines Virtualization
It is the process of running a virtual instance of a computer system in a layer abstracted from the actual hardware.
allows one computer to do the job of multiple computers, by sharing the resources of a single hardware across multiple environments
Provides
Abstraction – to simplify the use of the underlying resource (e.g., by removing details of the resource’s structure)
•Replication – to create multiple instances of the resource (e.g., to simplify management or allocation)
Isolation – to separate the uses which clients make of the underlying resources (e.g., to improve security)
