Virtualization in Computing Overview

A hypervisor that runs directly on the bare metal hardware without any underlying operating system.

A hypervisor that runs on top of an existing operating system. It's like a layer on top of your main OS.

A software-based computer that runs on top of a hypervisor. It is independent of the physical hardware and other VMs.

The process of allocating resources, like CPU, RAM, and storage, to virtual machines.

The benefit of virtualization that allows for cost savings by minimizing the need for physical servers.

The benefit of virtualization that minimizes floor space requirements by using virtual machines instead of physical servers.

The benefit of virtualization that simplifies maintenance and management by centralizing control over multiple virtual machines.

The benefit of virtualization that allows VMs to be moved easily to other physical servers, enhancing flexibility and reliability.

The benefit of virtualization that maximizes the utilization of a machine's resources by creating multiple VMs on a single server.

The benefit of virtualization that enables easy backups and disaster recovery by using software-based VMs.

Virtualization in computing is the process of creating a simulated environment of hardware and software resources within a computer system. This simulated environment mimics the real-world hardware, allowing multiple operating systems and applications to run concurrently on a single physical machine.

A virtual machine (VM) is a software-based emulation of a physical computer system. It allows you to run separate operating systems and applications on a single host machine, as if they were on individual physical computers.

A hypervisor is a core component of virtualization technology. It acts as a layer between the physical hardware and the guest operating systems. It manages the allocation of resources, scheduling, and communication between VMs.

A Type 1 hypervisor is installed directly onto the physical hardware, acting as the base layer of the system. It has full control over the hardware and runs independent of the host operating system.

A Type 2 hypervisor runs on top of a host operating system. It acts as a virtualized layer within the host OS, providing virtualization capabilities within that environment.

Virtualization offers several benefits, including cost savings by consolidating hardware, improved resource utilization, increased flexibility in deploying and scaling applications, and greater resilience through redundancies.

Servers that are physically separate, each with its own dedicated hardware and operating system.

Traditionally, organizations used one physical server for each application, leading to inefficient resource utilization and higher operational costs.
