What is Server Virtualization?

Computer NetworkInternetMCA

Server Virtualization is the phase of breaking a physical server into multiple virtual servers known as virtual private servers. Each virtual private server can run freely. The concept of Server Virtualization is broadly used in the IT infrastructure to diminish the costs by improving the utilization of existing resources.

Server Virtualization enables us to use resources effectively. In server virtualization, it can remove the major cost of hardware. This virtualization in Cloud Computing can break the workload to multiple servers and all these virtual servers are capable of implementing a dedicated task.

The main advantage of server virtualization is cost-effective because it can divide a single server into several virtual servers which removes the cost of physical hardware. Furthermore, the applications are no in high in need of their server as each virtual machine on the server works them.

Hypervisor plays an important role in Server Virtualization. It is a layer among the operating framework and hardware. There are two methods of hypervisors including Type 1 hypervisor and Type 2 hypervisor.

In server virtualization, it is broadly used in IT infrastructure as a technique of minimizing costs by enhancing the utilization of existing resources. Virtualizing servers is generally a good solution for small- to medium-scale software. This technology is broadly used for supporting cost-effective web hosting services.

Types of Server Virtualization

The types of server virtualization are as follows −

  • Full Virtualization

    Full Virtualization uses a hypervisor to directly connect with the CPU and physical server. It supports the best isolation and security structure to the virtual machines. It is similar to Para-virtualization. Therefore, machine operation used by the operating system is used to implement input-output or change the system status.

    The unmodified operating frameworks can run on top of the hypervisor. This is possible because of the operations, which are emulated in the application and the status programs are restored with what the real hardware can deliver.

  • Para Virtualization

    In the Para virtualization model the simulation is trapping overhead in software virtualizations. It depends on the hypervisor and the guest operating system and changed entry compiled for installing it in a virtual device.

  • Operating System Virtualization

    Operating system virtualization is also referred to as system-level virtualization. It is a server virtualization technology that divides one operating framework into multiple isolated user-space called a virtual environments. The main advantage of using server visualization is that it decreases the use of the physical area, so it will store money.

  • Hardware-Assisted Virtualization 

    Hardware-Assisted Virtualization was given by AMD and Intel. It is also referred to as Hardware virtualization, AMD virtualization, and Intel virtualization. It is created to improve the performance of the processor. The benefit of using Hardware-Assisted Virtualization is that it needs less hypervisor overhead.
