# Cloud Computing Virtualization

- In virtualization, a single physical instance of an [application](https://www.mindstick.com/articles/12824/calculator-application-in-android) or resource is shared among multiple [organization](https://answers.mindstick.com/qa/100623/what-is-the-role-of-the-world-health-organization-in-global-health) or tenants (customers).
- It does so by assigning a logical name to physical resources and providing a pointer to that physical resource when demanded
- Creating a [virtual machine](https://www.mindstick.com/forum/157900/what-is-a-virtual-machine-and-how-does-it-work) over existing [operating system](https://www.mindstick.com/articles/229069/operating-system-development) and hardware is referred as Hardware Virtualization.
- Virtual Machines provide an [environment](https://yourviews.mindstick.com/view/308/need-to-create-a-supportive-work-environment-for-women) that is logically separated from the underlying hardware.
- The machine on which the virtual machine is created is [known as](https://answers.mindstick.com/qa/35703/ricky-ponting-is-also-known-as-what) host machine and the virtual machine is referred as a guest machine.
- This virtual machine is managed by a software or firmware, which is known as a hypervisor.

##### Hypervisor

##

The hypervisor is a firmware or low-level program that [acts as](https://answers.mindstick.com/qa/51373/what-were-president-johnson-s-first-official-acts-as-president) a Virtual Machine Manager. There are two types of hypervisor:

Type 1 hypervisor runs on the bare system. LynxSecure, RTS Hypervisor, Oracle VM, Sun xVM Server, VirtualLogic VLX are examples of Type 1 hypervisor.

Note: The type1 hypervisor does not have any host operating system because they are installed on a bare system.

Type 2 hypervisor is a software interface that emulates the devices with which a system normally interacts. Containers, KVM, Microsoft Hyper V, VMWare Fusion, Virtual Server 2005 R2, Windows Virtual PC and VMWare workstation 6.0 are examples of Type 2 hypervisor.

##### Type of Hardware Virtualization

##

There are mainly three types of hardware virtualization:

1. Full Virtualization

2. Emulation Virtualization

3. Para virtualization

**Full Virtualization:** Here, the underlying hardware is completely simulated. Guest software does not require any modification to run

**Emulation Virtualization:** In Emulation, the virtual machine simulates the hardware and hence became [independent](https://answers.mindstick.com/qa/98599/what-is-the-longest-river-in-the-commonwealth-of-independent-states) of it. In this, the guest operating system does not require modification.

**Para virtualization:** In Para virtualization, the hardware is not simulated. The guest software run their own isolated domains

\

**Note:** VMware vSphere is highly developed [infrastructure](https://www.mindstick.com/news/2313/a-cybersecurity-and-infrastructure-security-agency-will-monitor-the-us-midterm-elections) that offers a [management](https://www.mindstick.com/articles/23490/tips-for-better-cash-flow-management) infrastructure framework for virtualization. It virtualizes the system, storage, and networking hardware
