# System Requirements for Large-Scale Deployment

The required deployment configuration relies on the custom deployment scenario, where Veeam ONE components are hosted as follows:

- [Veeam ONE Server](one_server.md) (on a dedicated machine)
- [Microsoft SQL Server](sql_server.md) (on a dedicated machine)
- [Veeam ONE UI](one_ui.md) (co-installed with Veeam ONE Server or run on a standalone machine)

Veeam ONE supports both virtual and physical servers for installation. This document describes a scenario where Veeam ONE components are installed on virtual machines.
