Understanding the Evolution and Re-Evaluation of VDI Deployments in Modern Businesses
The landscape of Virtual Desktop Infrastructure (VDI) is undergoing significant transformation. Businesses are now revisiting their decisions to implement, refresh, update, or replace VDI deployments, driven by recent advancements and changes introduced by leading vendors such as Citrix, VMware, Omnissa and Microsoft. This article aims to provide a comprehensive, vendor-agnostic analysis of these solutions, focusing on cost, licensing, sustainability, and deployment flexibility across public cloud, private cloud, or hybrid environments.
Virtual Desktop Infrastructure (VDI) has been a transformative technology for enterprises, enabling centralized management of desktops and enhancing security and accessibility. Market turmoil, driven by factors such as the change to licensing models from both Citrix and VMware, have sparked a renewed interest and re-evaluation of VDI implementations. Add to that Omnissa's emergence from the shadow of their former owner VMware and the release and general availability of Microsoft's AVD for Azure Stack HCI and you can understand why all industry verticals are placing this decision at the heart of their technology roadmap and strategy.
The Need for Re-Evaluation of VDI Deployments
VDI offers numerous benefits, however, several factors are prompting businesses to reassess their VDI strategies. The technology has become integral to modern businesses, VDI’s relevance has been further amplified by the increasing demand for remote work solutions, heightened security requirements, and the need for scalable and sustainable IT infrastructures.
Let's look at some of the reasons driving a decision to reassess.
Technological Advancements
VDI technology has undergone significant advancements, improving performance, scalability, and user experience. Innovations such as better graphics virtualization, enhanced network protocols, and AI-driven optimizations have made VDI more viable and attractive for a wider range of applications.
Changing Workforce Dynamics
The COVID-19 pandemic accelerated the shift to remote work, pushing businesses to seek robust and flexible solutions for remote desktop access. VDI provides an optimized, consistent and secure user experience, regardless of the physical location, making it an ideal solution for modern, distributed workforces.
Security Enhancements
With increasing cybersecurity threats, businesses are prioritizing secure computing environments. VDI inherently enhances security by centralizing data and reducing the risk of data breaches from lost or stolen endpoints. Recent improvements in security features by vendors have further solidified VDI’s role in an enterprise’s security strategy.
Sustainability and Business Continuity
Businessess alike have aspired to a growing emphasis on green IT and reducing environmental footprints. As governments across the globe strive towards the goal of Carbon Net Zero, enterprises likewise must conform in meeting this target.
Deployment flexibility aids in both this area and that of business continuity. The need to support diverse deployment models (public cloud, private cloud, hybrid), can aid in both reducing data centre footprint and providing a solution for continued service provison to clients and end users alike.
Cost
The biggest influencer driving re-evaluation of current VDI hypervisor deployments is cost!!
Both VMware and Citrix have recently revised their licensing models, leading to increased costs for customers:
VMware
Subscription-based Licensing: VMware has shifted from perpetual licenses to a subscription-based model. This change means that customers now pay recurring fees instead of a one-time purchase cost, leading to higher long-term expenses.
Price Increases: VMware has also raised the prices of its products, including vSphere and vSAN, citing increased development and operational costs as reasons for the hike.
Citrix
Move to Cloud Licensing: Citrix is transitioning customers from on-premises licenses to cloud-based subscriptions. Similar to VMware, this shift involves ongoing subscription fees rather than a one-time purchase.
Higher Subscription Costs: Citrix has increased the prices of its cloud services and subscriptions, attributing the rise to enhanced features and capabilities in their cloud offerings.
These changes are intended to drive revenue growth and encourage customers to adopt cloud-based solutions, but they also result in higher costs for existing customers.
Impact of Licensing Changes by VMware and Citrix
The shift by VMware and Citrix to subscription-based licensing models reflects a broader trend in the software industry towards more flexible and predictable pricing structures. This change has several implications:
Lower Upfront Costs:?Businesses can start with smaller deployments and scale up as needed without significant initial investment.
Operational Expenditure (OPEX):?Moving to a subscription model shifts costs from capital expenditure (CAPEX) to operational expenditure (OPEX), which can be easier to manage and justify within IT budgets.
Scalability:?Subscription models provide the flexibility to scale VDI deployments up or down based on business needs, ensuring that organizations only pay for what they use.
Microsoft
These changes have also opened the door for Microsoft, particularly with its AVD and AVD on Azure Stack HCI offerings. Microsoft’s competitive pricing, combined with its extensive cloud ecosystem, positions it as a strong contender in the VDI market.
Microsoft’s licensing for AVD is particularly attractive for organizations already invested in the Microsoft ecosystem, offering bundled pricing and integrated services that can lower total cost of ownership.

Decision-Making Considerations
When deciding whether to implement, refresh, update, or replace VDI deployments, it is imperative that they focus on:
Business Requirements
Understanding specific business needs, such as the number of users, performance requirements, and application usage, is critical. For instance, sectors like finance and healthcare may require high-performance solutions with stringent security measures.
Total Cost of Ownership (TCO)
Evaluating the total cost of ownership, including licensing, infrastructure, and ongoing maintenance, helps in making informed financial decisions. Subscription-based models may offer lower upfront costs, while perpetual licenses could be more cost-effective in the long run.
Scalability
The ability to scale the VDI solution in response to changing business needs is essential. Solutions that offer seamless scalability, can accommodate growing user bases and evolving IT requirements.
User Experience
Ensuring a seamless and responsive user experience is vital for productivity. Solutions known for their high performance and reliability, can significantly impact user satisfaction if not implemented and configured in accordance with both the constraints of the platform and/or the specific requirements of the use case in question.
Integration
The ease of integration with existing IT infrastructure and applications is another critical factor. Microsoft AVD, for instance, integrates well with other Microsoft products, which can simplify deployment for businesses already using the Azure ecosystem.
Support and Services
Access to reliable support and professional services can greatly influence the success of VDI deployments. Vendors like Citrix and VMware have extensive support networks, while newer entrants like Omnissa may offer more personalized service.
