What is virtualization | Answers and Benefits

 September 9th, 2019

Virtualization: The creation of a virtual resource (server, desktop, operating system, file, storage or network).  This creation is virtual (not physically existing but created by software to appear to look physical), not actual.  According to javatpoint.com, the concept behind virtualization is “[The] creation of a virtual machine over existing operating system and hardware is known as Hardware Virtualization.  A Virtual machine provides an environment that is logically separated from the underlying hardware.”

Operating System Virtualization

Multiple operating systems will run on a single piece of hardware.  Virtualization will essentially separate the physical hardware and software by emulating hardware using software.  When a different operating system is running on top of the system’s main operating system by means of virtualization, it is referred to as a virtual machine.  A lot of times, this is used for testing applications on different operating system platforms.

Hardware Virtualization

According to Wikipedia, “Hardware virtualization is the virtualization of computers as complete hardware platforms, certain logical abstractions of their componentry, or only the functionality required to run various operating systems.”  In other words, when virtual machine software, or the virtual machine manager is installed on the hardware system, it is known as hardware virtualization.  Its purpose is to “virtualize” hardware components such as the processor, memory and/or devices (hard drives, dvd/cdrom drives, etc).  Once the hardware has been virtualized, you will be able to install different operating systems that are capable of running in their own instance and able to run different applications and perform tasks.

Server Virtualization

Server virtualization is when the virtual machine or the virtual machine manager is installed on a server.  Essentially, it masks resources on the main server machine.  Typically this is used to divide the server into multiple isolated servers (virtual environments) for load balancing and for “on demand” requirements.  This is typically known as Virtual Private Servers, or VPS.

Storage Virtualization

This feature is typically the process of grouping or pooling physical storage devices to appear as a single storage device.  RAID for example could be construed as a type of storage virtualization.  Storage virtualization can be done from a single machine or from machines on multiple networks.  An example for use would be for the creation of VPS, back-up or recovery systems, etc.

Network Virtualization

According to sdxcentral.com, “Network virtualization (NV) is defined by the ability to create logical, virtual networks that are decoupled from the underlying network hardware to ensure the network can better integrate with and support increasingly virtual environments.”  Simply put, when you use virtualization in a network, software virtualization that consists of hardware and software networking resources (switches, routers, etc.) is created.  Physical networking devices forward packets, while the “virtual” network deploys and manages network services and resources.  This is utilized to support virtual environments.

The Benefits of Virtualization In The Cloud

Virtualization allows for multiple operating systems to be run.  Virtualization allows for more flexible and efficient allocation of resources.  Virtualization enhances development productivity and lowers the cost of IT infrastructure.  It promotes a more secure environment for remote access.  Virtualization allows for rapid scalibility.  Virtualization has a much higher availability and disaster recovery rate.
