Introduction to virtualization and Hyper-V
In this section, we will introduce the concept of virtualization, specifically in the context of compute – that is, CPU and memory – as opposed to storage or network virtualization.
Computers (machines), whether virtual or physical, are the core building blocks of on-premise solutions and Azure IaaS solutions.
The term we use for these virtualized physical machines is virtual machine (VM). VMs are the virtualization of a computer’s physical memory and processor resources; physical computers are emulated in software. This allows a physical machine’s resources to be subdivided and have a portion allocated to each virtual machine. Each VM runs its own isolated OS, the same as a physical server. The OS accesses virtual compute resources such as virtual processors (virtual CPU or vCPU) and virtual memory.
The next section will look at the relationship between physical computers and VMs.
