Microsoft Hyper-V is the second largest hypervisor on the market (after ESXi). Not least because of its integration into Windows Server (and Windows for PCs, too). The article will be long and detailed, so a thermos of something stronger won't hurt - I'll try to cover all the most important things, including licensing, system requirements, key features, and in the end I'll compare it with ESXi, KVM and Proxmox.
Let's get started.
What is Microsoft Hyper-V: About the hypervisor and licenses
Hyper-V is a Type 1 (Bare Metal) hypervisor from Microsoft. Hypervisors of this type run directly on the hardware, without pre-installing a host operating system. The structure is as follows: physical hardware → hypervisor → virtual machines (VM) → guest operating systems. The hypervisor completely isolates virtual machines from each other and wordpress web design agency emulates full-fledged hardware, although in fact it uses only a portion of the server's physical resources. This allows multiple users to work on virtual machines on one server without knowing about each other's existence and without interfering with each other (different guest operating systems, different application software, etc.).
A simple analogy from life. Imagine that the owner of a business, for example a hotel (host system), wants to use the rooms as efficiently as possible. He hires an efficient manager (hypervisor), who manages all the bookings, provision, preparation of the rooms for stay, hires other staff (other software), so that each guest (user) checks into a clean room (virtual machine) with all the amenities (dedicated host resources). The management, manager and staff do not care where the guest comes from, what language he speaks (different operating systems). A Russian (Astra Linux), a Chinese (Deepin), an American (Windows) and a European (openSUSE) can live in neighboring rooms without interfering with each other. The maximum they will cross paths in the elevator or at the exit from the hotel (common network channel of the host).
The main idea of a hypervisor is the optimal use of server computing resources, compatibility with various software tasks, and ease of administration. Correct and balanced implementation of a hypervisor/virtualization system increases system reliability, reduces recovery time after failures (RTO/RPO), saves administrators' time, and reduces the total cost of ownership of the IT infrastructure.
If your server is dedicated to one task, such as website hosting, then virtualization may be unnecessary (especially on paid software), but in many scenarios a hypervisor is justified, since you can distribute different services across different isolated VMs. For example, a mail server, a file server, a domain controller, an application server. One server instead of four, with easy scaling, maintenance, and without conflicts. Sounds good? And you can solve more complex problems.
