A VPS (Virtual Private Server) is an isolated virtual machine running on powerful physical hardware. Unlike classic shared hosting, you get dedicated CPU, RAM, and storage quotas for your instance, with root or administrator access and full freedom to install your OS and software stack.
This guide explains what a VPS is, how it works, what it's used for, and how to pick the right plan — including Infrawire NVMe VPS, Ryzen VPS, and Windows VPS tiers. For more power, read what is a dedicated server.
Definition: what is a virtual private server?
A VPS is created by a hypervisor (usually KVM on Linux) that splits a bare-metal server into independent virtual machines. Each VPS has its own operating system (Linux or Windows), IP addresses, disk volumes, and resource limits.
You get a guaranteed slice of hardware without renting the entire machine — the sweet spot between price, flexibility, and performance for most web, app, and game projects.
How does a VPS work in practice?
- KVM virtualization: isolation close to bare metal, unlike shared PHP hosting or lightweight containers.
- NVMe storage: fast disks for websites, SQL databases, Redis caches, and backups.
- Dedicated network: public IP, firewall, often Anti-DDoS included.
- Control panel: reboot, OS reinstall, console, RAM/CPU upgrades in a few clicks.
At Infrawire, VPS instances run in tier-1 datacenters (including Equinix PA5 in Paris) on network AS210699 — see our BGP network article.
VPS vs shared hosting vs dedicated server
| Criterion | Shared hosting | VPS (KVM) | Dedicated server |
|---|---|---|---|
| Resources | Shared, limited | Allocated to your VM | 100% of hardware |
| System access | Restricted | Full root / admin | BIOS, IPMI, RAID |
| Price | Very low | Moderate | Higher |
| Scalability | Low | Fast upgrades | Hardware migration |
| Typical use | Small brochure site | Web, API, games, VPN | High-traffic SaaS, hypervisor |

What is a VPS used for? Real-world examples
- Websites and e-commerce: WordPress, PrestaShop on VPS France or VPS Germany.
- Apps and APIs: Node.js, Python, Docker, microservices.
- Game servers: Minecraft, FiveM — choose Ryzen VPS for CPU-heavy loads.
- Remote desktops: trading, Windows workloads via Windows VPS.
- VPN and network tools: WireGuard, proxies, tunnels.
- Dev/staging environments: production clones at controlled cost.

How to choose the right VPS
- CPU: light web → Xeon Gold NVMe; builds, games, ETL → Ryzen.
- RAM: keep 20–30% headroom for spikes and caches.
- Storage: NVMe for databases; size backups properly.
- Network: latency to users, Anti-DDoS, optional BGP or extra IPs.
- Support: 24/7 response before your first critical incident.

Infrawire VPS tiers at a glance
| Tier | CPU | Best for | Link |
|---|---|---|---|
| NVMe VPS | Intel Xeon Gold | Sites, APIs, VPN | infrawire.net/vps |
| Ryzen VPS | AMD Ryzen | Games, CPU-heavy | infrawire.net/vps/ryzen |
| Windows VPS | Xeon / Ryzen | RDP, .NET, light SQL | infrawire.net/vps/windows |
| Cloud | Elastic | Variable workloads | infrawire.net/cloud |
Activation in minutes, clear billing, upgrades without changing providers. When a VPS is no longer enough, move to a dedicated server on the same infrastructure.
Frequently Asked Questions (FAQ)
What is a VPS in simple terms?
A virtual private server: an isolated slice of physical hardware with your own resources and OS, managed like a real remote server.
Is a VPS faster than shared hosting?
Usually yes: resources are allocated to you, KVM isolation limits noisy neighbors, and you control the software stack.
Can I host WordPress on a VPS?
Absolutely. An NVMe VPS fits most sites; step-by-step guide: WordPress on VPS.
What's the difference between Linux VPS and Windows VPS?
Linux (Debian, Ubuntu…) dominates web and DevOps; Windows Server fits .NET, RDP, and SQL Server — see Windows VPS at Infrawire.
When should I move from VPS to dedicated?
When CPU/RAM is constantly saturated, you need guaranteed disk I/O, or you want your own hypervisor (Proxmox). Hub: dedicated servers.
Does Infrawire include DDoS protection on VPS?
Yes — Anti-DDoS network protection is included on Infrawire VPS plans.
Conclusion
A VPS is the modern foundation for web and application hosting: power, control, and predictable cost. Start on NVMe VPS, scale to Ryzen or Windows as load grows, and move to dedicated when your project demands it.
