What is System Virtualization?

There has been a great deal and a number of solutions present in the market which can be utilized for application virtualization. The challenge occurs when the user falls into the pit of which software virtualization solution can provide a good trade off.

However, some explication about application virtualization should be done to remove the clouds of questions and doubts.

The term application virtualization illustrates software technologies that enhance the manageability and compatibility of previous application that had been used through putting in a nutshell applications from the hidden operating system where these applications were completed. In this process it should also be distinguished that the whole operating system and not just particular applications is virtualized.

How is this linked to software virtualization software?

To begin with, software virtualization software or SVS in short is the newest and most-up-to-date way of using software. The software usage happens by putting application and data into administered units which are called Virtual Software Packages. These packages permit the user to immediately activate, deactivate, or reset applications to entirely avoid inconsistencies and conflicts among applications without modifying the foundation of Windows installation.

This is the perfect tool to use in preventing conflicts among applications hence, previous software which do not offer this kind of feature should be exchanged with this software.

Centralized management of application can be attained if the right software virtualization solution is acquired and executed. To better emphasize this point, it should be noticed that SVS permits application and data to be gathered into virtual layers which in turn results in an organized and virtualized application.

Technology particularly virtualization technology has indeed plenty of contribution in the world of Information Technology. It can be traced back when virtual machine systems were developed and then from it yielded more form of hardware architecture including full virtualization and paravirtualization. This advanced technology is grounded with the idea that operating systems can be actually modified and the multiple OS can simultaneously run. Just one of the wonders of technology.

Nonetheless, the point of this matter is about system virtualization where in developers realized that the use of single computer with single operating system is no longer the reality to be dealt with. So, system virtualization lies with the ideas that the possibility that running multiple computer systems is indeed helpful.

System virtualization is achieved once a virtual duplication of the system’s hardware and operating systems run on the copied system the way they function on the original hardware. Given this wonderful truth about system virtualization, it is provided that applications and operating systems remain unaltered, totally unaware to the environment to which they are actually processing.

However, this story has also some disadvantages and that would be when an operating system that uses virtual memory calls for a page of memory the OS decodes the memory address from the application’s virtual space into the system’s real space which is illustrated through a page table. The retrieving of memory from the original space into the copied space and vice versa is a difficult task which could also be too expensive to maintain.

Though system virtualization can be beneficial it can also be provide additional cost as it tries to achieve a greater benefit. However, since virtualization is really an evolving technology the drawback that was mentioned will soon be eliminated. After all, technology can still stretch its limits.
