What is a VPS
A virtual private server (VPS) is a virtual machine that runs on a physical host server. Multiple VPS share the hardware resources of the host system. Each VPS behaves like an independent server with its own operating system, own IP address and root access.
How a VPS works
A hypervisor divides the physical hardware into multiple isolated environments. Each VPS receives a guaranteed base level of CPU, RAM and storage. At NexoraHost we use KVM virtualization – each VPS gets dedicated resources assigned, but can use additional performance when the host system has free capacity.
Resource allocation at NexoraHost
Our host servers are oversold, meaning the sum of all assigned resources across VPS can exceed the actual available hardware. In practice this rarely causes issues, as not all servers run at full load simultaneously. Typical overselling ratios are CPU 1:4 and RAM 1:1.2. This allows us to offer affordable prices while maintaining stable performance.
VPS vs. Root Server at NexoraHost
| Feature | VPS | Root Server |
|---|---|---|
| Resources | Shared, overselling possible | Dedicated, no overselling |
| Host utilization | Can exceed 100% | Maximum 100%, usually with reserve |
| Price | More affordable | Higher |
| Performance | Guaranteed base + burst | Full dedicated performance |
| Use case | Web hosting, small projects, game servers | Production environments, large projects, databases |
Root Server – dedicated resources
A root server at NexoraHost uses real dedicated hardware or heavily isolated dedicated resources. We allocate a maximum of 100% of server performance – never more. In most cases we intentionally leave some reserve free, so you always have the full performance available. This guarantees consistent performance without fluctuations caused by other users.
Which one is right for you?
- VPS: Ideal for beginners, small to medium web projects, test environments and game servers with moderate player counts.
- Root Server: Recommended for business-critical applications, large databases, high-traffic websites and game servers with high player counts.
