Virtual Machines
Main Post
Virtual Machine is an operating system which is installed on software and works as dedicated hardware. The end users will have the same experience on Virtual machines (VMs) as they would have on dedicated hardware. Virtual machine acts as an emulator for a machine which executes programs like a computer (Edwards, 1998). There are many advantages of using virtual machines. Virtual machines can provide an architecture for users which is different than the actual computer. It allows users to use more than one operating systems (OS) environments on the same machine. When a user creates a virtual machine, they basically create a hard disk so anything on VM can crash, but it won't affect the host machine. Virtual machines also provide more security to users by monitoring guest operation systems for inadequacy. However, Virtual machines are less efficient as compares to the real machines. They can be infected due to the weakness of the real machine which is hosting them. When many Virtual machines (VMs) are working on a single machine, they decrease the performance of the real machine because they require more power to run Virtual machines. Virtual machines will also use the resources of the host machine which also affect the performance of the real machine.

There are many virtual machines software that can be used in a host machine to create virtual machines. The most used software for creating Virtual machines (VMs) include VMWare workstation, VMware fusion, Oracle VM VirtualBox, Parallels desktop, cloud-based virtual machines, Microsoft Hyper-V, System Center Virtual machine manager, etc. These are some of the most used for implementation and management of Virtual machines.

Virtual machines are divided into two categories which include System Virtual Machines and Process Virtual Machine. They are implemented according to software emulation methods or hardware virtualization techniques. Virtual machines are dependent on the use and level of correspondence to any real machine. Virtual machines are usually implemented to perform operations which are different and can’t be performed on a real machine.
