When Unstable Networks Break Traditional VDI
Virtual Desktop Infrastructure (VDI) is a virtualization technology that hosts desktop operating systems and applications on centralized servers and delivers them securely to end users over a network. These desktops typically run inside virtual machines managed by platforms such as VMware or other enterprise hypervisors. While this model offers centralized control and security, it depends on one critical assumption: reliable, always-on connectivity.
For organizations operating in environments with unstable or limited connectivity, that assumption quickly becomes a liability. Remote workers, field teams, and global offices often struggle with dropped connections, high latency, and slow file access when using traditional VDI. Productivity suffers, users lose access to critical data, and IT teams spend hours troubleshooting. VDI profiles and files can become unusable or fail to synchronize due to WAN disruptions. Resilio Active Everywhere addresses this common problem.
The Challenge with Traditional VDI
Dependence on Constant Connectivity
Traditional VDI platforms such as Citrix, Azure Virtual Desktop, and VMware Horizon rely on continuous connectivity between desktop sessions, centralized storage, and the supporting control plane. When those environments are accessed over MPLS, VPNs, or unstable internet links, performance and user productivity can quickly degrade. Resilio enhances these deployments by keeping user data synchronized and locally available, improving availability and responsiveness even when network conditions are poor.
If WAN links degrade or drop, users often experience login failures, profile mount issues, slow file access, or session instability. In many environments, profiles and data shares are stored in centralized systems and aren’t connected. In many real-world environments, such as remote job sites or developing regions, this level of connectivity simply does not exist.
Latency, Downtime, and Sync Delays
Even when a connection is available, high latency can make remote desktops nearly unusable. File operations lag, applications respond slowly, and user experience deteriorates. Synchronizing large workloads, such as CAD files or analytics data, across wide-area networks can introduce additional delays, especially when bandwidth is constrained.
The result is a fragile system that performs well only under ideal network conditions and offers limited disaster recovery capabilities when connectivity is lost.
Why Offline-Ready Data Access Matters in VDI
Offline-ready VDI deployments reduce dependence on constant WAN connectivity by keeping user profiles and project files available locally. This helps users maintain productivity even when network conditions are disrupted.
It is particularly valuable for:
- Field teams operating in areas with intermittent connectivity
- Remote offices connected over slow or unstable links
- Global organizations with users spread across regions
- Industrial, energy, and defense environments with restricted, isolated, or air-gapped networks
In these scenarios, users need uninterrupted access to critical data and a consistent virtual desktop experience, regardless of network quality.
How Resilio Synchronizes Data for Resilient VDI
Resilio Active Everywhere enhances Citrix, Azure Virtual Desktop, and VMware Horizon deployments by synchronizing user profiles and file data across sites. This enables resilient VDI operations even when WAN connectivity is unreliable.
Learn more about Resilio VDI synchronization capabilities and architecture.
Peer-to-Peer Synchronization
Resilio uses a peer-to-peer architecture to distribute VDI-related user data (profiles, containers, and project files) across endpoints, sites, and cloud environments. This reduces reliance on centralized file servers and eliminates single points of failure that commonly disrupt traditional VDI deployments.
For example, a customer can maintain an SMB profile share at each site or region for FSLogix/Citrix profile containers, then synchronize the containers (and related user data) in real time so the Virtual Delivery Agent (VDA) can mount profiles locally in every location—enabling true multi-site active-active operations.
Offline Access with Automatic Synchronization
Resilio Active Everywhere keeps profile and project data available locally within each VDI site, reducing session disruption when centralized storage becomes unreachable.
When connectivity between sites is restored, changes synchronize automatically. Because profile and project data remain available locally at each site, VDI sessions are less likely to be disrupted by loss of access to centralized storage during WAN outages. No manual intervention is required, ensuring data consistency across environments while maintaining a seamless end-user experience.
WAN-Optimized Performance for Unstable Networks
Resilio is optimized for wide-area networks and poor connectivity. The Active Everywhere distributed data movement platform transfers only incremental file changes rather than entire files, significantly reducing bandwidth consumption and improving synchronization speed.
This WAN-optimized approach delivers faster VDI login performance when time-to-desktop is dominated by profile/container and user-share access over WAN. With Resilio synchronizing profiles and user shares locally, VDI logins and file access become more predictable, even over high-latency or low-bandwidth links.
Flexible Deployment for Enterprise VDI Environments
Resilio supports cloud, hybrid, and on-premises VDI deployments, allowing organizations to meet security, compliance, and data sovereignty requirements. Resilio Active Everywhere works with and distributes content across existing VDI storage patterns, including SMB/NAS profiles and user shares, in on-prem, cloud, and hybrid environments.
These capabilities make Resilio an ideal solution for offline-ready file access and synchronization in VDI environments, especially for remote offices and field teams.
Real-World Example: Resilient VDI for Remote and Field-Based Teams
A North American engineering and construction leader uses Resilio Active Everywhere to deliver a high-performance, resilient VDI environment for thousands of remote and field-based users operating across unstable and high-latency networks.
By combining Citrix Virtual Apps and Desktops, Microsoft FSLogix, Azure NetApp Files, and on-premises NetApp storage with our real-time synchronization, the organization enables engineers to access mission-critical applications, CAD drawings, and large 3D design files from any location. User profile data remains available locally, allowing work to continue even when network connectivity is degraded or temporarily unavailable.
Resilio automatically synchronizes user profile changes across multiple active sites, ensuring data consistency and fast recovery without manual intervention. This active-active VDI architecture eliminates downtime caused by network disruptions, reduces time-to-desktop, and delivers a consistent user experience across on-premises and cloud environments.
