It varies between which of the two types of VPS’s you use. There are two types of VPS’s: containers and cloud servers (VM).
Containers use a lightweight operating system virtualisation, and open-source operating system (OS) Linux. This makes them the cheapest solution available. Container VPS’s can cost as little as $7.26 per month.
Cloud servers use a resource-intensive hardware virtualisation, and provide each VM with their own OS. Linux VMs can cost from $8.56 per month, whereas Windows VMs may cost from $32.38 per month.
