# VPS Ultra

Simafri's VPS Ultra is a whole KVM virtual machine: your own kernel, memory reserved for you, a dedicated IPv4 address included, running Linux or Windows Server. You administer it with full access, and **Full-Stack Assistance** is included: describe what you are seeing, and we diagnose it and tell you what to do, from the system down to your application. You keep control of your server.

## Which projects is the VPS Ultra designed for?

Projects that call for a whole virtual machine: a kernel you tune yourself (a VPN such as WireGuard, modules, kernel parameters), reserved memory for a database or a demanding application, a dedicated IPv4 address, Windows Server, or direct mail sending from your own address.

## Three sizes

| Size    | vCPU | Guaranteed memory | NVMe SSD |
| ------- | ---- | ----------------- | -------- |
| Ultra 1 | 2    | 4 GB              | 60 GB    |
| Ultra 2 | 4    | 8 GB              | 120 GB   |
| Ultra 3 | 6    | 12 GB             | 200 GB   |

Every size includes its dedicated IPv4 address and the same level of service. Your server moves up to a larger size at any time, without reinstalling (see [Sizes and scaling](/en/vps-ultra/tailles-et-evolution.md)). Prices, monthly or yearly with one month free, are on the [VPS Ultra page](https://www.simafri.com/en/vps-ultra/).
