When evaluating VDI options on Azure, Citrix and Nerdio, it’s clear that each offers unique benefits.
This article provides a balanced comparison to help clients determine which platform best suits their VDI needs, with an emphasis on cost structure, features, and functionality.
1. Comparison Table: Citrix VDI vs. Nerdio on Azure
The table below provides a quick side-by-side comparison of Citrix on Azure and Nerdio, focusing on key aspects like cost factors, protocol efficiency, and scalability.
| Feature | Citrix VDI on Azure | Nerdio VDI on Azure |
| Cost Factors | Lower egress costs due to the efficient ICA protocol | Nerdio manages Azure Virtual Desktop (AVD), which includes cost optimization strategies that can significantly reduce overall deployment costs by more than 80%. Egress costs are a minor component (3%) of the total AVD cost, with primary expenses being compute and storage. |
Licensing and Runtime |
Optimized runtime with Autoscale, reducing VM usage hours | Upfront licensing may be lower, but runtime costs can increase based on VM usage |
| Scalability | Robust Autoscale tool to manage VM usage and save on costs | Basic scaling via Microsoft’s native tools |
| Protocol | Uses ICA, a lightweight protocol designed to minimize bandwidth costs | Uses RDP, a protocol requiring more bandwidth, impacting costs and performance |
| Ideal Use Case | Feature-rich and adaptable to complex, customized environments | Suited to basic environments with standard requirements |
Pro Tip: This table highlights some major considerations, but it’s essential to align these features with your specific requirements before making a choice.
2. Cost Factors
Egress Costs
One of the most critical aspects to examine when choosing a VDI platform on Azure is egress cost. Citrix’s ICA protocol is optimized for performance and bandwidth efficiency, which can help manage egress costs effectively.
In contrast, Azure Virtual Desktop (AVD) uses an improved version of RDP that also focuses on efficiency and cost-effectiveness. Nerdio manages AVD and utilizes RDP; while RDP traditionally requires more bandwidth, the actual impact on egress fees can vary based on specific usage patterns and configurations. For instance, while egress costs for Azure can reach up to $0.087 per GB in some scenarios, effective management strategies can help mitigate these expenses for organizations with large data transfer needs.
Licensing and Runtime Costs
While Nerdio’s licensing fees may seem lower on the surface, Citrix’s Autoscale feature enables optimized VM management by powering machines on and off as needed, reducing runtime hours and potentially saving on overall costs. According to Citrix’s documentation, Citrix Autoscale provides advanced scaling capabilities that optimize resource usage and reduce costs. However, this doesn’t imply Nerdio lacks advanced tools; Nerdio also offers automation features for Azure Virtual Desktop that can effectively manage and optimize costs.
3. Feature Highlights
Citrix’s Advanced Autoscale Tool
Citrix’s Autoscale is ideal for companies managing complex environments with variable VM usage. This tool actively reduces costs by ensuring VMs only run when needed, which can make a notable difference for companies with large deployments or fluctuating workloads. Citrix Autoscale indeed offers sophisticated power management features, such as schedule-based and load-based scaling. However, Azure Virtual Desktop (managed by Nerdio) also includes robust automation tools that can efficiently handle scaling and cost management.
Nerdio for Simple and Complex Environments
Nerdio offers comprehensive solutions for both simple and complex environments when managing Azure Virtual Desktop. It provides advanced features and scalability options suitable for a wide range of organizational needs.
Its ease of setup may be attractive to companies seeking a no-frills solution, but they should carefully consider the feature trade-offs involved, especially if scaling and custom configuration are priorities.
4. User Experience and Protocol Efficiency
Protocol selection affects both performance and cost. Citrix’s ICA protocol is designed for high efficiency, reducing bandwidth requirements and lowering egress costs without sacrificing the user experience. Nerdio’s use of RDP, while functional, requires more bandwidth, which can influence both performance and long-term egress expenses. For companies with significant VDI activity, ICA’s lower bandwidth demands may result in both cost savings and a smoother user experience. This protocol efficiency is a critical factor in choosing the best VDI solution for Azure: Citrix or Nerdio.
5. Choosing the Right Platform: Citrix or Nerdio?
To help clarify which VDI solution may suit your organization’s needs best, see the table below comparing factors like company size, environment complexity, budget, and data usage.

Consideration
|
Better Fit for Citrix
|
Better Fit for Nerdio
|
| Company Size | Mid to large enterprises with complex needs | Small to mid-sized companies with basic needs |
| Environment Complexity | High; requires advanced customization or scaling | Low; standard or “vanilla” environments |
| Budget Focus | Willing to invest in tools like Autoscale for long-term savings | Upfront cost-sensitive, with short-term budget focus |
Data Transfer Needs |
High; large amounts of data transfer expected, so lower egress costs are critical | Low to moderate data transfer needs |
User Experience Priorities |
Prioritizes smooth, efficient user experience through ICA protocol | Standard user experience with RDP protocol |
This table is designed to highlight which solution might align more naturally with your company’s priorities, but keep in mind that a tailored evaluation is recommended to address specific needs. The cost comparison of Citrix and Nerdio for Azure VDI should also factor in how egress rates impact your bottom line.
Selecting between Citrix and Nerdio is more complex than just a comparison of licensing costs or ease of use. Citrix’s advanced features and cost-saving mechanisms, like Autoscale and ICA, make it highly suitable for complex environments requiring robust management and user experience. Nerdio, on the other hand, may work well for standard environments, but companies should remain cautious of higher egress costs due to RDP and a more limited feature set.
Key Takeaways
- Consider Total Cost: Egress costs and runtime fees may affect your budget significantly. Citrix’s ICA protocol and Autoscale tool are designed to control these costs, while Nerdio may carry higher egress fees due to RDP’s bandwidth usage.
- Match the Platform to Your Needs: Citrix’s feature-rich VDI infrastructure is built for complex or larger-scale environments, while Nerdio suits smaller setups needing a simpler solution.
- Prioritize User Experience: Citrix’s ICA protocol can enhance user experience through efficient bandwidth use, which may benefit companies with high VDI activity.
- Plan for the Long-Term: If scalability and custom configurations are in your future, Citrix may be a better fit, while Nerdio could serve basic needs well if growth isn’t a priority.
Hopefully, this article equips you with the main considerations to confidently choose between Citrix and Nerdio on Azure for your VDI needs.
