Windows Server: what it is in simple words
Windows Server is a server operating system from Microsoft designed for network management, data storage and running enterprise applications. It provides centralized management of users, printing, files and security in an enterprise environment. Below is where it is used, how to choose a version and how it relates to procurement.
- Versions: 2016, 2019, 2022 — newer versions support more security and performance features.
- Roles: domain controller (AD), file server, print server, web server (IIS), application server.
- Licensing: by cores or by users/devices — depends on the server role.
- Import substitution: for government bodies a transition to domestic OS is required (Astra Linux, RED OS) — Windows Server is not in the Unified Register.
- Security: Group Policy, BitLocker, Windows Defender, auditing — built-in protection tools.
- Hardware requirements: 64-bit processor, at least 2 GB RAM (8+ recommended), SSD for the system.
- Virtualization: Hyper-V — built-in hypervisor for running virtual machines.
- Support: Microsoft provides extended support for 10 years from a version release.
- For SMB: Windows Server 2022 Standard — domain controller and file server.
- For data centers: Windows Server 2022 Datacenter — virtualization and high availability.
- For government: consider Astra Linux / RED OS to meet import substitution requirements.
- Small office: 1 server with AD and file server.
- Large office: cluster of 2+ servers with Hyper-V and redundancy.
- Data center: virtualization on Hyper-V managed via System Center.
- 44-FZ / 223-FZ, KTRU; for government — import substitution requirements.
- FSTEC certification for personal data processing systems.
- Information protection requirements per GOST.
- Windows Server is not in the Unified Register — government needs a replacement.

Use the newest supported LTS version appropriate to the company size: Standard for 1-2 servers, Datacenter for clusters and virtualization-heavy environments.
Which Windows Server is right for my company?
Small office — 1 server with AD and files; large — cluster of 2+ with Hyper-V; data center — Datacenter edition with System Center.
