Definition
VPS (Virtual Private Server) hosting is a hosting model in which a physical server is divided into multiple isolated virtual machines, each with dedicated CPU, RAM, and storage allocations, giving users root-level control without the cost of a full physical server.
Overview
VPS hosting sits between Shared Hosting, where many customers share the same server resources and operating environment, and Dedicated Server Hosting, where a customer gets an entire physical machine to themselves. A hypervisor splits one physical server into several virtual machines, each running its own isolated operating system and allocated a guaranteed share of CPU, RAM, and Block Storage, so one tenant's traffic spikes or misconfiguration can't directly degrade another's performance the way they can on shared hosting. Because each VPS behaves like an independent server, users typically get root or administrator access, letting them install custom software, configure firewalls, and run control panels like cPanel or Plesk — or skip a panel entirely and manage everything via the command line. This flexibility makes VPS hosting popular for growing websites, custom application stacks, and development or staging environments that need more control than shared hosting allows. VPS hosting can be either 'unmanaged,' where the customer handles all server administration, or 'managed,' where the provider handles OS updates, security patching, and monitoring — a distinction similar to the managed/unmanaged split seen in Managed WordPress Hosting. It's a foundational hosting concept covered early in cloud and infrastructure courses like AWS Core Services.
Key Concepts
- Physical server divided into isolated virtual machines via a hypervisor
- Guaranteed, dedicated CPU, RAM, and storage allocations per instance
- Root or administrator-level access for full customization
- Available as managed or unmanaged, depending on provider
- More resource isolation and predictability than shared hosting
- Lower cost than a full dedicated server
