Join us in this blog as we delve deep into the essential components of Virtual Desktop technologies, uncovering how they can optimize hybrid work scenarios within your organization. Let's explore the world of virtual desktops, unraveling their potential and possibilities.

What Is a Virtual Desktop?

A virtual desktop refers to a software simulation of a hardware device operating on a physical or virtual machine situated remotely, whether on-premises or in the cloud. Platforms like Azure Virtual Desktop exemplify this concept by allowing users to remotely access their personalized desktop setups via a network. This encompasses the complete desktop experience, including operating systems and software applications, accessed through client software or web browsers on their preferred endpoint devices.

How Does a Virtual Desktop Work?

Virtual desktop infrastructure operates through virtual machines to provide virtual desktop experiences across a range of connected devices, using two main approaches: persistent and non-persistent.

In a persistent virtual desktop setup, each user is assigned a distinct desktop image exclusively customized by them, complete with personalized apps and data. This configuration retains all applications and files even through reboots, maintaining user settings for each login. This consistent approach resembles the familiarity of a physical PC environment, promoting user adoption and proving particularly advantageous for power users. Managing individually customized virtual desktops entails unique considerations for storage and software updates, differing from non-persistent virtual desktop solutions.

On the other hand, a non-persistent virtual desktop infrastructure allows users to access virtual desktops from a shared pool of available options. These non-persistent virtual desktops replicate from a common "golden" desktop image, generating a fresh instance upon each user login. Personalization of non-persistent virtual desktops occurs through user profiles, scripts, or specialized software, though any changes made during sessions, such as app installations, are discarded. Reduced storage needs result from storing user configuration settings and data separately. When a user logs out, the virtual machine reverts to its base image state, ready for the next user. Administratively, non-persistent desktops are easier to manage due to the consistent base image, often making them more popular than persistent desktops.

In the realm of VDI, creating multiple virtual machines from a single physical machine is orchestrated by a hypervisor in on-premises environments. This hypervisor ensures server operating system isolation, intercepting commands directed at the underlying hardware. It facilitates multiple operating system instances via virtual machines (VMs), all utilizing a shared hardware platform. This hypervisor and underlying infrastructure are abstracted within public clouds, allowing administrators to interact directly with virtual machines and leverage cloud-native actions and APIs.

Given that virtual machines mimic physical machines but draw resources from a single computer system, virtualization enables IT organizations to run multiple operating systems on one server or within a single public cloud account. This spans from Microsoft Windows 10 and Windows Server 2019 to Linux and FreeBSD. Computing resources—like CPU, RAM, and disk space—are allocated to each virtual machine by the hypervisor or public cloud as required. This form of server virtualization serves as the bedrock of cloud computing.

Enhanced Security Features

Virtual desktops bring forth notable security advantages. VDI (Virtual Desktop Infrastructure) enables precise control and secure data isolation, avoids data storage on endpoint devices, and subsequently minimizes vulnerability to theft. As sensitive data remains within the data center, IT gains the capability to conduct audits and manage security incidents more effectively. This proves particularly pivotal in industries subject to stringent regulations, ensuring compliance.

Efficiency in IT Operations

Due to the centralized management nature of VDI, which operates from a data center or public cloud, administrators can seamlessly apply software patches, updates, configure settings, and enforce policies for all virtual desktops across the deployment. This encapsulated environment also provides developers a safe space to test applications without jeopardizing the production setup.

Cost-Effectiveness

Despite users interacting with applications on virtual desktops as if they were on physical devices, the virtual desktops themselves reside within virtual machines on servers within on-premises or cloud data centers. As computational processing occurs in these central data centers, virtual desktop technology allows organizations to opt for more budget-friendly endpoint devices instead of high-performance desktop clients.

Seamless Scalability

A dependable VDI solution simplifies scaling crucial applications and services to accommodate a growing population of mobile users and remote teams. Whether expanding the workforce temporarily—such as with seasonal employees or contractors—or embracing a permanent shift towards a widely dispersed remote workforce, organizations can swiftly extend the VDI environment. This agility enables users to become operational within minutes, gaining instant access to enterprise virtual desktop workloads and associated applications.
