# VPS or dedicated server: how to choose for your project?

A suitable server starts with a precise description of your workload. The number of visitors alone is not enough: a lightweight API and a heavily used database may require different resources.

## The short answer

Choose a VPS to get an isolated virtual environment with a defined configuration. Prefer a dedicated server when your project requires an entire physical machine, more resources or management of your own virtualized environments.

- Measure CPU, RAM, storage and network before comparing plans.
- Root access is available on both ranges; it does not turn a VPS into an exclusive physical machine.
- Include backups and administration in your budget.

## What is the difference between a VPS and a dedicated server?

A VPS is a virtual machine. With KVM, a hypervisor provides multiple isolated environments with their virtual hardware: processor, memory, disks and network interfaces. Each environment can run its own system, while the physical server remains the shared foundation.

A dedicated server assigns the physical machine to your project. You choose how to use its resources, either directly or through your own virtualization layer. This architectural difference matters more than the number of cores shown in a table alone.

| Point of comparison | VPS | Dedicated server |
| --- | --- | --- |
| Environment | Isolated virtual machine | Reserved physical machine |
| Processor | Allocated vCPU | Configured processor |
| Control | System of the VPS | System and machine organization |
| Sizing | Selected virtual configuration | Resources of the selected server |

## Start by measuring your application

Observe the memory used during normal periods and during peaks, the processor load and the disk space actually required. An application waiting on its database will not necessarily benefit from a larger processor. Poorly suited queries, caches or indexes can explain the slowness.

Add the less visible operations: application builds, backups, data imports or scheduled processing. These tasks can concentrate the load at a different time than visits. Keep a margin rather than sizing exactly to the level of the last observed peak.

## Compare the resources that change your usage

Distinguish storage capacity, network port throughput and traffic volume. A port at 1 Gbps describes throughput; unmetered traffic describes volume billing. These are two different characteristics. RAID concerns disk organization and does not constitute an independent backup.

In the WispHost catalog, VPS come with 4 to 64 GB of RAM and dedicated servers with 32 to 512 GB. These ranges allow you to compare the ranges; they do not replace a test with your application and your dataset.

## Who will administer the server?

Root access allows you to manage the system. It also means preparing updates, access rights and restoration. Have the division of responsibilities between your team and the host clarified, then verify that your deployment tools work on the chosen system.

Keep a copy of your data outside the server and test its restoration. A strategy exists when you know which files to recover, where to find them and how to bring the application back into service, not only when a backup is scheduled.

## Also choose your region

The distance between the server, your users and your other services influences the network path. Look in particular at the location of your database or large files. For a latency-sensitive need, request an appropriate test point rather than inferring a measurement from the city name alone.

The WispHost selectors show six regions for VPS and three for dedicated servers. The price updates with the region. Check this choice in the summary, as well as the duration and any options.

## A simple decision to document

Choose the VPS if its resources and environment match your workload. Consider the dedicated server if you need the entire machine or if your sizing exceeds the virtual range. Before ordering, note your measured needs, your backup strategy and the criteria that will trigger a configuration change.
