10 Popular uses of Virtual Machines

In the digital computer world, a virtual machine (VM) is an emulation of a certain computer system. Virtual 
PC machines work on computer architecture and use real or hypothetical computer functions where their versions 
can include specialized hardware, software or a combination of both. That is, a virtual machine is a program that 
acts as a virtual computer where it runs 'the host operating system' on your current operating system and supplies 
virtual hardware to guest operating systems.

The guest operating system would then run as if it were running on a real physical computer, and from the perspective 
of the guest operating system, the virtual machine appears to be a real, physical computer.

The guest operating systems running in Windows can be called Microsoft Virtual Machines on your host operating system, 
just like any other program on your computer and there are other types of virtual machines that you know, such as Linux Virtual Machine,
Java Virtual Machine, and VMware virtual machine.

Components of Virtual Machines

Virtual machines are built to provide users with their own virtual hardware, including a virtual CPU, memory, hard drive, 
network interface, and other devices. The virtual hardware devices provided by the virtual machine are stuck to your physical machine 
in real-life hardware. For example, the virtual hard drive of a virtual computer is stored in a file that is located on your hard drive.

In addition, you can install a few virtual machines on your system where you are limited only by the amount of available storage space. 
Once you have installed OS on your virtual machines, you can open your virtual computer program and choose which virtual machine 
only wants to boot when the guest operating system is activated and your host operating in a window Running on the system.

A popular use for virtual machines

 Virtual machines have a great array of uses that will certainly come in handy. Here are the top 10 reasons to use virtual machines:

1) Take a spin on newer versions of operating systems: With virtual machines, you can use a secure method to run the 
development version of Windows 10 on your Windows 8 computer. This method allows you to run a Windows 10 trial without 
installing an unstable version of Windows on your computer.

2) Virtualization from your own desktop: There is a arrive trend in the IT community where users store their operating systems
and desktop applications on a distinct virtual machine in the server and use their PC as a "thin client" for the server. 

Each user is isolated from all other users using virtual machine technology and the maintenance of the applications is moved from each 
user's desktop to the data center.

3) Test with different operating systems: You can also install various distributions of Linux or other lesser-known operating systems in a 
virtual machine to experiment with and understand how they work. Multiple operating systems can be run on the same server, 
eliminating the need to dedicate a single machine to an application.

If you have a sudden fascination or tendency in Ubuntu, you can actually install it in a virtual machine and dabble with it in a window 
on your regular desktop.

4) Use of software that requires an outdated operating system: In a situation where you have an important application running 
on Windows XP, you can install XP on a virtual machine and run the rather prehistoric application on the virtual machine where compatibility 
is not a problem. The best part is that with virtual machines you can use an application that only works with Windows XP without 
installing Windows XP on your computer, which is really handy as not much hardware fully supports Windows XP.

5) Run software formatted for other operating systems: Linux and Mac users can as well run Windows in a virtual machine to run 
Windows software on their computers without the compatibility headaches of Crossover.

6) Moving and Mimicking: Virtual machines are like transferable independent packages. It is relatively easy to move a virtual machine 
from one server to another to keep the workload in balance, to migrate to faster hardware and recover from hardware errors. In addition, 
virtual machines can easily be simulated and implemented.

7) Test software on many different platforms: In a case where you have to test whether an application works on multiple operating systems, 
you can set up in a virtual machine instead of a huge number of various computers applicable for each.

8) Consolidation: With virtual machines, it eliminates the need to dedicate a single machine to an application. Older and newer applications can 
be run together with their related operating systems on multicore servers with numerous threads, energy consumption and saving space in the 
data center. The latest versions of the operating system and new applications can be implemented without buying new hardware.

9) Compile different servers for business use: For companies running multiple servers, their existing servers can be inserted into virtual 
machines and run on a single PC. Each virtual machine is isolated, so this does not cause security problems related to the execution of different 
servers on the same operating system. VM’s can also be moved among physical servers.

10) Security and protection: As mentioned earlier, due to the isolation of virtual machines, an attack or violation of piracy in one does not affect 
the others. The fault tolerance and security that comes with the isolation of each virtual machine is an important benefit of virtualization. 
This means that virtual machines can save you time and effort in troubleshooting and repair.

The blog would have given you a basic idea about how virtual machines work and their popular uses.

The concept of virtual machines and virtualization has evolved during the period with concentrated efforts of organizations such as Vmware, 
Citrix, Windows, etc. to optimize the infrastructure challenges facing the industry. IT professionals can expect a career in virtualization itself with 
great opportunities available worldwide.

The demand for professionals with virtualization skills has been constantly increasing. 

At the same time, there are some good online IT courses on virtualization, with which you can learn from the basics to advanced implementations,
Cloud computing training in Chandigarh institute is one of the best cloud computing courses provided institute.
