Virtual Machines : Definition, Types, Functions, & Advantages

Did you know virtual machines are? In the rapidly growing digital era, everything in the world can be stored and integrated into cloud services and virtual systems. Such systems are known as Virtual Machines. Companies, especially in the technology sector, use Virtual Machines for the smooth running of the company’s business.

So, what is Virtual Machine? Check out this article, OK!

What is Virtual Machine ?

Virtual machine (VM) is engineering software that has a function like a physical computer, with complete development components. Simply put, this VM is an additional operating system that works on a virtual server like the computer’s default OS.

software is able to perform activities like a computer in general. Starting from installing applications, creating e-mail files, running programs, system updates, and so on. Even though it was created on a piece of hardware, Virtual Machine can take advantage of the Hypervisor software to separate VM resources from hardware.

The implementation of this technology can be described as a second space on a computer, without affecting the state of the main computer. Of course, this is ideal for testing computer programs or updating operating systems, and it’s also useful for opening files with virus risk.

In a cloud computing, VM technology is widely used because it can run operating system, and function independently of the device. In addition, the operating system can also be operated simultaneously on host or device.

Types of Virtual Machine

Virtual Machine has several types, namely:

  1. Process Virtual Machine

type of virtual machine is a process virtual machine. This type of virtual machine also allows an operating system to be operated as the main application on the device or device that is the host. This type of VM is able to provide a programming environment that is independent of software platform .

This VM hides information from a hardware or operating system that underlies a device, so that the appearance and function of the device can be changed completely. The Java Virtual Machine is an example of this type of VM, where Java applications can run on OS .

  1. System Virtual Machine

The second type is a system virtual machine. This kind is totally virtualized and may perform the same functions as a real computer.This platform also supports the need share resources from the host to several Virtual Machines. Then, each VM can later run a standalone copy of the OS. The process of virtualization also depends on the performance of the Hypervisor, which can operate on hardware or on top of an operating system.

Advantages of Virtual Machines  

Virtual machines are useful for increasing productivity within the company. Here are the advantages of virtual machines, when compared to computing conventional

  • VM is much more flexible and efficient. In one device, users can take advantage of various operating systems for various needs.
  • Software on virtual machines is much easier to manage, maintenance costs are also cheaper.
  • Empower users to achieve their ultimate goals with performance, and quality that goes beyond computing conventional
