7/4/2023 0 Comments Virtualmachine![]() ![]() Think of a virtual environment as the IT services that need to use the physical hardware’s resources. VMs are created through a process called virtualization, which uses software - also known as a hypervisor (explained next) - to separate the physical hardware resources from the virtual environment. As such, the end-user experience emulated within a VM is nearly identical to that you’d expect on a physical machine. For example, you can run Windows, Linux, and macOS on the same PC, and each OS runs precisely as it would on the host hardware. VMs also allow multiple different OSes to run simultaneously on a single hardware system. You can also move them easily between host servers depending on demand and efficiently use the dedicated hardware’s resources. Since VMs are abstracted from the rest of dedicated hardware, many of them can exist on a single piece of hardware. While the parts (CPU, memory, storage, and NICs) that make up your PC are physical and tangible, VMs are software-defined computers or virtualized computers within physical hosts, existing only as code. ![]() It has its own CPU, memory, storage, and network interface card (NIC) - created from a physical server - that allows it to run its own operating system (OS) and application environment separate from the dedicated hardware. Definition of a Virtual MachineĪ VM is a computer file that behaves like an actual physical personal computer (PC). In this post, we’ll explore what a VM is, how VMs work, their advantages and disadvantages, and other terminology associated with virtualization. Increased performance, greater workload mobility, and automated operations are some of the benefits that virtual machines (VMs) provide, making IT simpler to manage and less costly to operate. In recent times, however, organizations are increasingly using the technology to enhance IT agility while creating significant cost savings. As early as the 1960s, IBM was already using virtualization to develop robust time-sharing applications. While the IT sector’s focus on virtualization technologies has significantly increased over the past couple of years, the concept has been with us for much longer. ![]()
