Short answer: A VPS (virtual private server) is a virtual machine rented on a shared physical server, with its own operating system, root access, IP address and a guaranteed share of RAM and storage. It costs from about $2 to $20 per month for typical plans and sits between shared hosting and a dedicated server.
VPS (virtual private server) explained
A physical server is divided by a hypervisor (usually KVM) into several virtual machines. Each VPS boots its own kernel and operating system, gets its own public IP address and a fixed amount of memory and disk, and is isolated from the other customers on the same machine. CPU cores are normally shared between tenants unless you buy a dedicated-CPU plan.
Compared with shared hosting, a VPS gives you root access, guaranteed resources and freedom to install any software: Docker, a game server, a VPN, a trading terminal or several websites. Compared with a dedicated server, it costs a fraction as much, can be resized in minutes and is backed up and moved by the provider, at the price of sharing hardware with neighbours.
People use VPS hosting for websites and online stores, self-hosted apps (n8n, Nextcloud, OpenClaw), forex and trading terminals on Windows, game servers, VPN and proxy endpoints in a chosen country, bots and development servers. The main choices when buying one are location, operating system (Linux or Windows), RAM, storage type (NVMe or SSD), traffic allowance and whether you want it managed.
Benefits over shared hosting: dedicated resources, root access, a static IP, better security isolation and the ability to scale. Drawbacks: you are responsible for updates and security unless you buy a managed plan, and a misconfigured server is your problem, not the host's.
