Hyper-V | Windows Server

Hyper-V is a hardware virtualization product developed by Microsoft. Hyper-V can create and run virtual machines, each virtual machine acts like a complete computer. Hyper V is available as a server role for Windows Server and it can subdivide the hardware capacity of a single host computer by allocating the host’s hardware resources to multiple Virtual machines. It provides an isolated space for each Virtual machine to run its own operating system that’s independent of the host’s OS and other Virtual machines. An operating system that runs in a Virtual machine is called a guest operating system. 

Virtual machines give you more flexibility, help save time and money, and are a more efficient way to use hardware than just running one operating system on physical hardware. Server Virtualization can create separate virtual machines and run them concurrently on a single server that is running Hyper-V. These virtual machines are guests, while the computer that is running Hyper-V is the virtualization server.

Hyper-V is a Type-2 hypervisor that runs inside the Windows operating system, The type-2 hypervisor runs inside an operating system of a physical host machine. Checkpoints are static images of the data on a virtual machine at a given moment and it not a replacement for backups. Checkpoints are stored on the same volume as the virtual hard disks.

Virtual Machine

A virtual machine is a software computer that, like a physical computer, runs an operating system and applications. Every virtual machine has virtual devices that provide the same functionality as physical hardware but are more portable, more secure, and easier to manage. A VM contains its own virtual (software-based) CPU, RAM, hard disk, and NIC.

Virtual Hard Disk

A virtual hard disk is a file that represents a hard disk drive that can be configured as a virtual hard disk with partitions and an operating system. Dynamically expanding virtual hard disks use only the space that it needs and it grows as and when data is added to them.

Virtual Switches

Virtual switches are a virtual version of a network switch, Hyper-V has three types external, internal, and private.

External Virtual Switch: This type of Virtual Switch maps a network to a specific network adapter.

Internal Virtual Switch: This type of Virtual switch communicates between multiple virtual machines on the Virtualization server and between the Virtual machines and the virtualization server.

Private Virtual Switch: Private Virtual Switches communicate between multiple virtual machines on the Virtualization server. Private Virtual switches can’t communicate between the Virtual machines and the virtualization server.
