Virtual Computing, Thin Clients & Virtual Desktop Infrastructure (VDI)

Virtual computing enables multiple users to access independent desktop environments using centrally managed computing resources. Instead of every user requiring a powerful desktop PC, applications and operating systems run on central servers, cloud infrastructure or virtual machines, while users connect through thin clients, zero clients or existing computers.

Modern virtual computing solutions are widely used in education, business, healthcare, government, manufacturing and call centres, providing secure, scalable and cost-effective desktop environments. With today's powerful servers, high-speed networking and cloud technologies, organisations can deliver Windows, Linux and other virtual desktop environments to users almost anywhere.

What is Virtual Computing?

Virtual computing separates the user's desktop environment from the physical hardware. Each user receives an independent virtual desktop running on a server or cloud platform, while a thin client, zero client or existing PC provides keyboard, mouse, display and network connectivity.

Users experience their own secure desktop session with applications, files and settings, while IT administrators manage software, updates, security and backups centrally.

Thin Clients and Zero Clients

• Thin Clients - Compact computers that include a lightweight operating system and minimal local storage. They connect to remote desktops, virtual machines or terminal servers while performing only limited local processing.
• Zero Clients - Dedicated endpoint devices with virtually no local operating system or storage. They are designed specifically for connecting securely to virtual desktop environments using remote display protocols.
• Repurposed PCs - Existing desktop or laptop computers can often be converted into virtual desktop endpoints using remote desktop software, extending hardware life and reducing upgrade costs.

Benefits of Virtual Computing

• Lower hardware replacement costs.
• Reduced power consumption.
• Centralised software installation and updates.
• Simplified system administration.
• Improved security through central data storage.
• Easy deployment of new users and desktops.
• Supports remote work and hybrid work environments.
• Extends the useful life of existing computer hardware.
• Simplifies backup and disaster recovery.
• Scales easily as organisations grow.

Common Virtual Computing Technologies

• Virtual Desktop Infrastructure (VDI).
• Desktop as a Service (DaaS).
• Remote Desktop Services (RDS).
• Cloud-hosted virtual desktops.
• Application virtualisation.
• Server-based computing.
• Remote application publishing.

Typical Applications

• Schools, colleges and universities.
• Business offices.
• Call centres.
• Healthcare facilities.
• Government departments.
• Libraries and public access computers.
• Retail and point-of-sale environments.
• Manufacturing and industrial workstations.
• Remote and hybrid workforce deployments.

When Virtual Computing Works Best

Virtual desktops perform exceptionally well for office productivity, web browsing, email, accounting software, ERP systems, CRM applications, document management, remote access and general business applications. Central management makes them particularly attractive where many users require similar desktop environments.

Workloads That May Require More Powerful Solutions

Modern VDI platforms can support graphics acceleration using dedicated GPU hardware, making many creative, engineering and multimedia workloads possible. However, high-end 3D rendering, advanced CAD, professional video production, scientific computing and demanding modern games generally require specialised GPU-enabled virtual infrastructure or dedicated workstations for the best performance.

Buying Guide

When selecting virtual computing solutions, consider the number of concurrent users, application requirements, network bandwidth, storage performance, security requirements and future scalability. Thin clients are ideal where a lightweight operating system is beneficial, while zero clients offer simplified deployment and enhanced security for dedicated virtual desktop environments.

Also evaluate monitor support, USB peripheral compatibility, display resolution, network connectivity, remote desktop protocols and management software to ensure compatibility with your existing IT infrastructure.

Frequently Asked Questions

What is virtual computing?

Virtual computing allows desktop operating systems and applications to run on central servers or cloud infrastructure while users access them from thin clients, zero clients or other endpoint devices.

What is a thin client?

A thin client is a compact computer with a lightweight operating system that connects to a centrally hosted desktop or application environment.

What is a zero client?

A zero client is a dedicated endpoint device designed specifically for connecting to virtual desktops without requiring a traditional local operating system.

Can multiple users share one server?

Yes. Modern virtual computing platforms allow many users to run independent desktop sessions simultaneously on shared server infrastructure.

Is virtual computing suitable for gaming?

General-purpose virtual desktop environments are primarily designed for business and productivity applications. High-end gaming and advanced 3D workloads typically require specialised GPU-enabled virtual infrastructure or dedicated gaming hardware.

Can users work remotely with virtual desktops?

Yes. Virtual desktop solutions can provide secure remote access to desktop environments from offices, homes and other supported locations using appropriate network connectivity.
