Virtual Private Server (VPS)

A Virtual Private Server (VPS), also referred to as a virtual dedicated server (VDS), is a virtual machine provided as a service by hosting providers, such as Pulsed Media. VPS hosting allows users to enjoy many of the benefits of a dedicated server—full root access, customizability, and isolation—while maintaining the affordability and efficiency of shared infrastructure.

Pulsed Media VPS plans are powered by cutting-edge technologies like KVM, Proxmox, and LXC, delivering high-performance, fully isolated environments for your applications and services. Whether you're hosting a website, running a game server, or building out a development stack, our VPS offerings strike the perfect balance between power and cost.

History of Virtual Private Servers

The roots of virtualization date back to the 1960s, when IBM pioneered techniques to partition mainframes into separate environments, allowing multiple users to access computing resources simultaneously. This foundational concept evolved into modern server virtualization.

By the early 2000s, as demand for web hosting surged, virtualization technology matured to a point where individual users could run isolated server environments on shared physical hardware. This gave rise to VPS hosting, which rapidly became a mainstay in the hosting industry.

Virtualization Technology

VPS hosting relies on two major types of Virtualization:

At Pulsed Media, we use both approaches depending on your use case. Our premium plans utilize KVM (hardware virtualization) for maximum compatibility and control. Our lightweight options leverage LXC containers for unmatched efficiency.

Proxmox VE

Proxmox Virtual Environment is a complete open-source server management platform. It supports both KVM and LXC and offers a powerful web interface.

Pros:

  • Unified management of VMs and containers.
  • Built-in backup, clustering, and firewall features.

Cons:

  • Some learning curve for beginners.
  • Requires Linux proficiency for advanced features.

Pulsed Media utilizes Proxmox extensively for virtualization management. It allows us to maximize uptime, flexibility, and operational efficiency.
