Hello, and welcome to my blog!
This week, we will discuss virtualization.
But what is virtualization, and why is it used? Well, virtualization is the process of
running an operating system in an app window on your desktop that behaves like
a physical computer.
Another great feature of virtualization is the ability to
run applications in a sandbox environment. Meaning, you can test applications
in a safe place protected from interacting with your computer, or you can try
different operating systems like Linux to see if it is right for you.
There are different types of virtualizations, such as
Hardware Virtualization, Desktop visualization, Application Virtualization,
Memory Virtualization, and my favorite, Video Game Console Emulation. Of course, there are many more types of
virtualizations, but I will not be going over all of them today as this blog
could take a long time explaining each one of them. I will be going over the
ones I just mentioned in the best detail that I could.
Hardware Virtualization
This
type of virtualization refers to creating a virtual machine that emulates like
a real computer with an operating system. Applications on these types of
virtual machines are separated from the hardware resources. This can be
explained if a computer running Windows may host a VM that seems like a
computer with a different operating system, such as Ubuntu Linux OS.
Desktop Virtualization
This is
the idea of separating the logical desktop from the physical machine. Desktop
Virtualization is often hosted on a remote central server, rather than a hard
drive on a physical computer. Chances are you may have experienced a virtual
desktop at work and did not notice.
Application Virtualization
Also
known as process virtualization is a software technology that encapsulates
computer programs from the operating system on which it is executed.
Memory Virtualization
In a
data center, memory virtualization decouples volatile random-access memory or
RAM from a computer system. It then aggerates those resources into a virtual
memory pool, which is then available to any computer in a cluster or network.
The collection of memory is then accessed by an operating system or application
running on top of the operating system.
Video Game Emulation
It is a
type of emulator that allows a computing device to emulate a video game
console’s hardware. So, that game that you enjoyed playing back in the NES days
can be played on your phone or tablet with an emulator.
Of course, there are many more types of VM out there, and a good portion of them are free to use, such as VirtualBox, VMware Player, and
VMware Fusion, just to name a few.
So, is there a VM you like using? Have you had issues with
them? If so, please leave a comment below!
Until next time!
I generally want quality content and I found that in your post. The information you have shared about virtualization is beneficial and significant for us. Keep sharing these kinds of articles here. Top Virtualization Training in Delaware
