Desktop virtualization is a technology that separates the physical location of a desktop environment and its applications from the device that is used to access it. Instead of applications and data residing on a local hard drive, they are centralized on a remote server. End users can then access their personalized desktop environment, applications, data and settings from any internet-connected device, regardless of operating system or location.
Benefits of Desktop Virtualization
Desktop virtualization offers numerous benefits for both organizations and end users. Some of the key benefits are:
Increased IT Agility and Manageability
With desktop virtualization, IT administrators have complete control over the centralized desktop environments and applications. Administrators can quickly roll out new desktops, applications or operating systems from the data center rather than having to touch each individual endpoint device. Troubleshooting issues also becomes easier since the core computing environment is hosted remotely rather than scattered across many physical machines. Any changes made at the server-level instantly apply to all virtual desktops, saving immense time during rollouts, updates and maintenance cycles.
Enhanced Security and Compliance
Centralizing desktop services helps strengthen security in multiple ways. Firstly, end user data never resides on the physical devices, eliminating the risk of data loss or theft. All user data, settings and credentials are kept securely on centralized servers within the organization’s infrastructure. Next, virtual desktops can be isolated through virtual machine environments, keeping work separated from personal activities even when using unmanaged personal devices. Virtual desktops also make it easier for organizations to apply and monitor security policies at a systemic level.
Improved Business Continuity and Disaster Recovery
Since the core desktop infrastructure exists independently in data centers, desktop virtualization provides businesses continuity even during disruptive events. In times of regional outages, health emergencies or other unplanned situations where employees cannot access physical offices – they remain productive with their virtual desktop environments. Virtualization also makes disaster recovery planning simpler by allowing quick restoration of environments from centralized backups.
Enhanced End User Experience
For end users, virtual desktops deliver a consistent and personalized computing experience regardless of device or location. Users can seamlessly switch between their PC, laptop, tablet or thin client at home or on the move while maintaining the same customized desktop layout, applications, data and settings. Multi-device access empowers mobile workstyles and flexible work arrangements. Users also benefit from the responsibility and security of having no sensitive or proprietary data stored on personally-owned devices.
Device Agnosticism and Flexibility
Since virtual desktops detach the OS and applications from hardware, organizations gain tremendous flexibility to choose their endpoint devices. Physical machines no longer need high-end specs and can be inexpensive thin clients, zero clients or even shared devices. This reduces capital expenditures on hardware refreshes and expands portability options. Users are no longer tied to specific machines either and can use any internet-connected device to access their desktop services.
Cost Savings and Optimized Licensing
Procuring, managing and supporting a variety of diverse physical endpoints becomes unnecessary with virtual desktops. Less needs to be spent on new PCs/laptops, peripherals and complex support contracts. Desktop virtualization also helps optimize licensing costs by separating user profiles from devices. For example, employees can temporarily use desktop services from loaner devices without the need to purchase new licenses. Organizations can also rightsize their licensing needs based on active rather than perishable user counts. Overall IT costs reduce through simplified management and support models.
Types of Desktop Virtualization: Hosted VDI and Hybrid VDI Environments
There are two primary types of desktop virtualization deployment models based on where computing resources are hosted.
Hosted VDI: In a hosted VDI environment, both the virtual desktops and their supporting infrastructure like RAM, storage, processing power etc. are hosted entirely within a private or public data center. Users connect remotely to their centralized virtual desktops over the network using thin/zero clients or repurposed existing PCs/laptops. Hosted VDI is highly scalable, cost-effective, centrally manageable but requires high-bandwidth connectivity.
Hybrid VDI: Hybrid VDI blends physical and virtual desktop paradigms. While core applications and data remain hosted in data centers like Hosted VDI, lightweight local virtual machines are deployed on physical endpoints using hypervisor software. Local VMs bootstrap into hosted sessions upon sign-in, giving users the feel of native desktops while retaining centralized management and mobility benefits. Hybrid VDI offers lower latency than fully hosted setups while reducing infrastructure load.
Hosted VDI is simpler to manage since nothing resides on end devices, while Hybrid VDI is ideal when stable network connections cannot be guaranteed. Most large organizations transition to Hybrid VDI models for their optimal balance of features, security, TCO and end user experience.
Desktop Virtualization Platforms and Key Implementations
Major vendors in the virtual desktop infrastructure space include VMware, Citrix, Microsoft and Nutanix. Each offer comprehensive VDI solutions consisting of hypervisors, connection brokers, hosting/session virtualization, app/profile layers, management consoles etc.
Some common desktop virtualization implementations across industries are:
– Healthcare: Clinical desktops for doctors, tablets for nurses, pooled lab PCs and flexible work-from-home access.
– Call Centers: Pool of virtual agent desktops with self-service management and geo-independent access.
– Education: Hosted lab environments, BYOD-ready classrooms, pool desktops and app-based learning.
– Remote Workforce: Secure VPN-less remote access to mission-critical systems for field engineers and traveling employees.
– Government: Centralized secure access infrastructure for citizen services portals, shared access controls and auditing.
– Retail: Shared point-of-sale and kiosk environments, store-switching flexibility, mobile merchant devices.
Widespread adoption of desktop virtualization is transforming the delivery, consumption and management of desktop computing resources across all types of organizations worldwide.
Concerns and Considerations with Desktop Virtualization
While desktop virtualization offers immense benefits, certain concerns remain during initial planning and implementation stages. These include:
Network Dependence: Reliance on stable high-bandwidth network connectivity for smooth interactive experiences. Local failures require contingency planning.
Initial Investment: Set up requires capital expenditure for infrastructure, licensing, specialized skill sets and testing/validation phases.
Learning Curve: Employees/students new to virtual environments may face adjustment issues compared to native desktops.
