While running multiple virtual machines, the hypervisor schedules operations so that resources do not overrun each other. The role of a hypervisor is to allocate and distribute resources to VMs, for instance, storage and memory from the hosts.

The entire process is managed by a software hypervisor. End-users can run multiple virtual machines on a single computer. VMs run as an isolated partition on its host computer wherein it uses power, CPU, operating system (Windows, Linux, macOS), and other resources. The physical machines on which virtual machines run are known as host machines. Some examples are DocGeneration Engine (DGE), and Sprint, a scalable document software solution for CCM (Customer Communications Management).Virtual machines are virtual environments that work as physical machines within a computer. Greater security provided : fast programming of backups facilitates the backup of virtual machines.ĭocPath’s document solutions software is designed to take advantage of the benefits of virtual machines in the cloud.On these occasions, a virtual machine is the preferred option. For instance, it may happen that the disk storage capacity becomes overloaded, that the user needs a more powerful machine in case of a high workload, or that the server becomes too small. Provides elasticity, flexibility and scalability: a virtual machine allows to increase or decrease the power of an infrastructure quickly and easily according to the user’s needs.This would save costs by not having to invest in equipment that may not be used on a regular basis. Possibility of pay-per-use included : in general terms, virtual machines can be purchased on a pay-per-use basis.Provides greater accessibility: being available in the cloud, it can be accessed from anywhere if an internet connection is available.No hardware investment require d : unlike a physical machine, the setup of virtual machines does not require physical components, therefore prevents organizations from spending money on the maintenance and renewal of these devices.Virtualization and virtual machines offer a range of advantages to be considered: Both processes are carried out quickly and easily technical problems are avoided too. In this way, a copy of a virtual operating system is made possible from a computer to another, as well as the generation of backup copies. All of the elements in a virtual machine are included in a set of files.From the RAM and hard disk, to the CD-ROM drive, video card and network card, are included in a virtual machine, the virtualization of all these elements being the only difference with respect to a real computer. Elements composing a virtual machine are the same as those available in a physical computer.O perating systems’ mode of use from a virtual machine is identical to that of an operating system installed on any computer.Therefore, if a virtual machine suffers any problem or stops working directly, others will not be affected and will continue their course and functioning. Each operating system that is being virtualized is completely independent from the rest of the operating systems.Notwithstanding, there exist others allowing only one operating system to be displayed.

Main Characteristics of a Virtual MachineĪfter defining virtual machine concept and having exposed some of its functionalities, it is essential to know its principal characteristics: However, there are applications that allow and facilitate the transfer of files and data from the host to the virtual machine. All this emulation is invisible to the operating system running the virtual machine, but all components work just as a computer will do.Įven if virtual machines are physically working inside another computer, the y cannot access to the host machine. This type of virtual machine emulates a complete computer: it has its storage disk, graphics card, RAM memory and the rest of the hardware components of a PC, but in this case virtually.
As the term says, it is not a physical and tangible machine, but one that we can only see virtually or emulated.Īlthough it is true that there exist several types, the most commonly used virtual machine is the “system” virtual machine. In general aspects, a virtual machine is a software able to load another operating system inside it, pretending to be a real PC. This way, it is possible to save space in the data center and reduce the need for physical servers. Over the last 15 years, virtual machines have been gaining strength, due to organizations which have opted for server virtualization to use the computing power of their physical servers much more efficiently.
