2. How Does VPS Work?

What is VPS and how does it work?

Imagine a physical server:

• This server has powerful hardware like CPU, RAM, and storage.
• Traditionally, this server could be used to host one website (dedicated hosting), or be divided into smaller sections for multiple websites (shared hosting).

VPS uses virtualization technology:

• This technology essentially creates virtual partitions within the physical server.
• Each partition acts like a separate, isolated server with its own dedicated resources like CPU, RAM, and storage.
• This allows multiple VPS users to share the physical server, but each user has their own dedicated space and resources.

Here’s what happens when you use VPS:

• You rent a VPS plan from a hosting provider.
• The provider configures a virtual partition on the physical server based on your chosen plan (e.g., amount of RAM, storage).
• You get root access to your virtual partition, giving you complete control over its settings and software.
• You can install your operating system, applications, and configure everything according to your needs.
• Your website runs on your isolated virtual server, unaffected by other users on the physical server.
