Introduction

OS Virtualization or Operating System Virtualization works as the last mode of Cloud Computing Virtualization. It is the mode of virtualization of the server.

OS Virtualization means in which we use software that lets system hardware run different operating systems on a single computer. These multiple operating systems can be used for running different applications without interfering with each other.

In this virtual system, the Operating system accepts commands given by its users and runs several applications on the computer. 

  1. Uses of OS Virtualization
  2. How Does OS Virtualization work?
  3. Types of Operating System Virtualization
  4. Advantages of OS Virtualization
  5. Disadvantages of Operating System Virtualization

1) Uses of OS Virtualization:

The following purposes of using Operating System Virtualization will tell you the importance of this system in Cloud Computing:

  1. Operating System Virtualization separates different applications into multiple particles or containers. 
  2. Operating System Virtualization creates the Virtual Hosting Environment. 
  3. Operating System Virtualization or OS Virtualization moves its resources on individual servers by integrating server hardware.
  4. The resources get security by the Operating System Virtualization as these resources get harmed by suspicious users.

2) How Does OS Virtualization work?

In this OS Virtualization, All hardware, as well as software from the computer, can be managed by the OS. The OS allows the running of multiple computer programs simultaneously on the machine with the help of the CPU of that computer. The Operating system connects to some parts of the device so that each application and program can run successfully on that device.  

3) Types of Operating System Virtualization:

There are two types of Virtualization in OS: 

  1. Windows Operating System Virtualization – In this virtualization, you have to install VMware Workstation Software in the first place. Then you can install Windows Software virtually. 
  2. Linux Operating System Virtualization – You have to install VMware software in the first place for installing any software. OS Virtualization requires installing VMware software in the first place to virtualize the Linux Operating System as well.

Also, OS Virtualization in cloud computing works via two virtual disks. Therefore, the client will be able to connect to that disk through the network. 

  1. Shared Disk – Multiple companies/ clients can use the shared disk at a time. The change created by the companies applies separately and clears the cache. Other clients’ settings will not be affected after the restarting of this system. The system sets as default after the restarting process. 
  2. Private Disk – A single company/client can use a private Disk. The client/ company stores the information that is based on assigned capacity.             

4) Advantages of OS Virtualization:

The advantages of virtualization in the operating system are as follows: 

  1. Traditional Deploy in Traditional Experience in each computer takes more time to load separately. Compared to the traditional system, OS Virtualization can be deployed quickly in seconds. 
  2. Operating System Virtualization saves money and time as it doesn’t require more maintenance due to the non-requirement of any hardware. 
  3. Operating System Virtualization is a space-saver system too. It doesn’t need the physical space used by the IT system because every instance of this system is virtual. 
  4. Operating System Virtualization helps companies to get better Return on Investment on the purchase. Because Companies use server hardware with great efficiency. Also, Companies enhance their operational works.
  5. In OS Virtualization, fewer machines mean low maintenance, less power, more electrical saving, and less requirement of cooling systems. 
  6. OS Virtualization is a good example of a security system as it finds resources in the number of mutual distrust users. 
  7. The server hardware can be merged by using this virtualization by the system administrator. This can be processed by moving the resource to an individual host combined with two containers.  

5) Disadvantages of Operating System Virtualization:

  1. Operating System Virtualization supports only a single operating system for the guest OS and as the base in the single server. The client can use a single OS, either Linux or Windows. 
  2. The container should have the same OS version and the same patch level as the base OS.
  3. If the base OS crashes, all virtual containers become unavailable inaccessible. 

Conclusion

In this mode of virtualization, the OS can lock up materials. Hence, such material doesn’t see in the calculation results when the computer reads the program. 

The program can be run in containers in which only a fraction of these materials have been assigned. Some containers may introduce a single operating system that included a variant of computer resources that have been assigned.

The operating system uses virtualization software so that different OS can be run with the help of server hardware. OS Virtualization is used by many clients/Companies due to its flexibility, cost-saving facility, and reliability. 

In this type of virtualization, the Operating system runs by the OS Kernel by giving access to reproduce the operating system on each separate platform.

OS visualization offers a wide range of benefits to companies/users. This virtualization is not only compatible with small companies but also useful for large businesses.
