A virtual machine is a type of computer application used to create a virtual environment, which is referred to as virtualization. Virtualization is defined as a logical view between computer hardware systems and the software used to operate them. Virtualization allows the user to see the infrastructure of a network through a process of aggregation. Virtualization may also be used to run multiple operating systems at the same time. Through the help of a virtual machine, the user can operate software located on the computer platform.
There are several different types of virtual machines. Most commonly, the term is used to refer to hardware virtual machine software, also known as a hypervisor. In computing, a hypervisor, also called virtual machine monitor (VMM), is one of many virtualization techniques which allow multiple operating systems, termed guests, to run concurrently on a host computer, a feature called hardware virtualization. It is so named because it is conceptually one level higher than a supervisor. The hypervisor presents to the guest operating systems a virtual operating platform and monitors the execution of the guest operating systems. Multiple instances of a variety of operating systems may share the virtualized hardware resources. Hypervisors are installed on server hardware whose only task is to run guest operating systems. Non-hypervisor virtualization systems are used for similar tasks on dedicated server hardware, but also commonly on desktop, portable and even handheld computers.
A virtual machine is essentially a software container that bundles or “encapsulates” a complete set of virtual hardware resources, as well as an operating system and all its applications, inside a software package. Encapsulation makes virtual machines incredibly portable and easy to manage.
At front end, it will basically contain a web portal. Web would be having user authentication. Server will be having all rights to change anything like giving permission, etc. It may also be showing which machine is using which O.S, for how much time it is using it. Here we can assign a particular session to be given to client machines.
At back end, it would contain an virtual box. A virtual machine is a tightly isolated software container that can run its own operating systems and applications as if it were a physical computer. A virtual machine behaves exactly like a physical computer and contains it own virtual (i.e., software-based) CPU, RAM hard disk and network interface card (NIC).
