What is a virtual server?

A virtual server, or Virtual Private Server (VPS), is a form of server virtualization that allows partitioning a single physical server into several independent virtual servers. Each virtual server operates as if it were a separate physical server, with its own operating systems, allocated resources, and applications. This separation is made possible by virtualization software, which simulates the existence of multiple independent machines on a single physical hardware.

How does a virtual server work?

Unlike shared hosting, where resources are shared between multiple users, a VPS allows the user to benefit from dedicated resources in an isolated environment. This means you have your own operating system, dedicated resources in terms of CPU, RAM memory, and storage, as well as complete freedom on server configuration.

Technically, a VPS is created by dividing a physical server into several independent virtual servers via virtualization software. Each virtual server runs autonomously and can be restarted independently without affecting other units on the same hardware.

Virtualization: The technology behind virtual servers

Virtualization is at the heart of virtual server technology. It uses a hypervisor, a software that allows to create and manage several virtual machines on a single physical unit. The hypervisor acts as a management layer between the hardware and the different operating systems, ensuring that each virtual server has the resources to operate efficiently without interfering with other servers sharing the same hardware.

Compared to physical servers, virtual servers offer several significant advantages, especially in terms of cost, flexibility and resource management. Unlike a physical server, where resources can be underutilized, each virtual server can be adjusted to accurately use the amount of resources needed, optimizing energy efficiency and reducing overall costs.

What are the benefits of virtual servers for businesses?

  1. Isolation: Each VPS is isolated from the others, providing a higher level of security than shared hosting.
  2. Customization: Users can install any software that runs on the server’s operating system, which provides considerable flexibility to customize the server according to the specific needs of the company.
  3. Scalability: It’s easy to increase the resources allocated to a VPS to support your business growth without disrupting ongoing operations.
  4. Cost-effectiveness: The VPS offers a cheaper solution than renting a dedicated server, while enjoying a substantial share of the benefits of a dedicated server.
