Virtualization

Virtualization is the process of creating virtual versions of physical resources, such as servers, storage devices, or network resources, allowing multiple operating systems or environments to run on a single physical machine. It enables greater resource utilization, isolation, and flexibility, making it easier to manage IT infrastructure. Virtualization is commonly implemented through a hypervisor, which abstracts the hardware and allocates resources to virtual machines (VMs).

Types of Virtualization:

Hardware Virtualization: Allows multiple operating systems to run on a single physical machine by virtualizing the hardware. Software Virtualization: Creates virtual instances of applications or services, enabling isolated execution environments. Network Virtualization: Combines network resources, such as bandwidth and IP addresses, to create a virtualized network environment.
