Virtualization

pc

Virtualization is the process of creating a virtual instance of a computer resource, such as a server or storage device.

expanded

Virtualization involves running multiple virtual instances on a single physical system, allowing for resource consolidation and better utilization. It provides a method to efficiently manage system resources by isolating applications and users on different virtualized environments, thereby optimizing hardware performance and reducing costs.

examples

An example of virtualization is using VMware ESXi to run multiple virtual servers on a single physical server, each with its own allocated CPU cores, memory, and storage.

This setup is commonly used in enterprise data centers to improve hardware utility and decrease the number of physical servers needed.

Using Oracle VirtualBox to create isolated virtual machines on a personal computer, which can host different operating systems for development and testing.

This is frequently employed by developers to test applications on different operating systems without requiring additional physical hardware.
