Difference between Application Virtualization and Paravirtualization?

Difference between Application Virtualization and Paravirtualization?
There are several categories of virtualization currently making their way to change the computing world before our very eyes. However, we will be looking at the differences between application and paravirtualization; and see at what level of popularity they are working on. Furthermore, we will also be looking at how both of these virtualization types can affect each other in the near future. Let us start:

Application Virtualization:

Application virtualization is a software technology that is able to be assimilated on to the underlying operating system on which it is present on. To make the understanding much more lucid, take the example of the Windows 7 operating system. The Windows 7 operating system has the functionality of providing users with a Windows XP Mode that allows older Windows XP applications, which were previously incompatible on the Windows 7, to run without hindrance on the new platform. That being said, there are several advantages of using application virtualization:

1: This allows certain applications to run in environments that are incompatible with the original applications (like the Windows 7 operating system)

2: This form of virtualization also allows some Microsoft Windows applications to run on the Linux operating system.

3: A virtual machine uses higher amount of computer resources compared to application virtualization resources, making the latter the obvious choice.

4: Run majority of the incompatible applications.

There are some limitations of using application virtualization. First of all, not all software can be virtualized. This is because some applications require a device driver to run properly. Furthermore, some applications that need to run in shared memory space.


Paravirtualization is a virtualization technique that allows the execution of a software interface to be placed in a virtual machine. The only difference is that there will be no incorporation of additional hardware. The function of the modified interface will be to reduce the portion of the user’s execution time that is being spent on performing operations which are considered to be more difficult to run in a virtual environment than a non-virtual environment. Currently, para-virtualization methods are still under development and will obviously have limitations such as the level of security, and cache data.

Can The Two Virtualization Forms Be Integrated In The Future?

Right now, the world of virtualization is going through a complete metamorphosis. With other virtualization techniques such as full virtualization are taking computing to the next level and beyond. However, the question that jumps right in is that is there a way that two virtualization techniques can exist in a single system. Yes they can. How? Since full virtualization techniques comprises up of a system that is completed isolated from different virtualized applications, there will be a time where the requirement of synergistic behavior from simultaneous virtualized applications will be required in order to make a more flexible virtualized environment.

Currently, full virtualization applications are highly secure thanks to the isolation of virtualized applications. However to provide a flexible workflow, more virtualization techniques will be required in order to speed up level of productivity.

Finally, here a pioneer and leading virtualization software company “VMware” that provide certification in virtualization. If you want to have a great career opportunity, getting certified in virtualization is the best thing to do. This is an ideal source to succeed.
