Virtualization – Everything you need to know

Our era is the pinnacle of digitization where data is the most important commodity. But due to the presence of system storage and processing limitations present in the x86 servers, there are many IT companies that are opting for alternatives or employing different methods to cater their storage-related needs.  But some of these techniques such as multiple server deployments, etc. are not only extremely inefficient but also costly. So, the best way to combat all these issues is through virtualization.


Virtualization is an art through which benefits of hardware are simulated with the help of a software with the result being the creation of a virtual machine or a computer system. With the help of such virtual systems, organizations have the capability to fully harness the power of their servers. In such scenarios, a single server can run multiple virtual machines which in turn enables the running of several operating systems simultaneously. Virtualization allows scalability of system’s architecture and improves the level of efficiency. 

Virtualization Types

  • Server Virtualization: This type of virtualization involves the running of several virtual machines on a single host without any server related complexities. Server virtualization has a high level of efficiency, lessened costs, greater server availability time, swift deployment process and better performance of applications.
  • Network Virtualization: A network virtualization is a functioning replica of an actual physical network. The virtual network allows applications to run without any hardware dependency.
  • Desktop Virtualization: Virtualized desktops are perfect for off-shore and remote employees as this managed service takes care of ever-changing workplace requirements immediately. 

Virtual Machines

A virtual machine is a virtual operating system which is an operating system with an application packed inside a secluded software container. These virtual machines are self-sufficient and do not rely on any other application. The physical computer that has these virtual machines installed on it is called a host or a physical server. The host and virtual machines are separated via a hypervisor which is a thin software layer that is responsible for the dynamic allocation of computing resources for each virtual operating system.

Virtual Machine and its Properties

Virtual machines have many distinctive characteristics that have beneficial properties. Some of these major properties are listed below:

  • Partitioning: In simple words, partitioning is the division of a physical system’s resources among virtual ones. This allows multiple virtual operating systems to run on a single computer.
  • Isolation: Isolation of a virtual machine from the host computer ensures hardware-level security and optimum performance level.
  • Encapsulation: The beauty of virtual machines also lies in their easy transfer. You can save, copy and move their entire state like a file.
  • Hardware Independence: Virtual machines are not hardware dependent due to which they can be easily migrated to a new server without any hassle.

A myth about Virtualization and Cloud Computing: People often confuse virtualization with cloud computing and vice versa but these two terms are poles apart. Virtualization enables hardware independence via software while cloud computing allows sharing of computing resources.

Server virtualization is the unsung hero of the IT world. It comes with cost-effectiveness, efficiency, and agility. It has a flexible structure that gives adequate room for scalability. This also reduces the risk of server downtime and enables disaster recovery.
