Virtual Desktop Interface technologies, such as Citrix and VMware Horizon, are key enablers of remote work, allowing for seamless access to applications and services employees consume when otherwise in the office. As remote work is likely to continue for some employees, some of the time, the dependencies and volume added to these technologies can vary greatly. Business tasks performed by remote workers must be maintained at acceptable user experience levels, but this can be challenging in several ways:
- Volatility in the number of remote workers causes shifts in the ingress/egress traffic patterns into the data center. Citrix ICA, EDT, and other VDI transports are extremely sensitive to latency that may result from high bandwidth utilization and poor QoS allocation. This necessitates ongoing monitoring to ensure they are meeting the demands of remote workers.
- The VDI infrastructure was not designed for this sudden shift in users and could be strained. Visibility into the performance of VDIs ensures that metrics and KPIs are available for both capacity planning and troubleshooting complex problems.
- Since the remote-to-datacenter connection of every remote worker’s access is different, there is a need for an objective analysis of VDI performance and the underlying applications its serves to effectively maintain and troubleshoot the entire service chain.
Leading Financial Ensures Quality Experience for Users of Virtual Desktop Infrastructure Over VPNs
NETSCOUT provides visibility throughout the service delivery path to quickly pinpoint whether a disruption is due to the VPN, VDI or application.
The NETSCOUT Solution
NETSCOUT’s service assurance solutions provide visibility from the core to the edge, as well as insight into end-user experience.
Assure remote workers who depend on a VDI solution receive acceptable performance when accessing application services by quickly pinpointing bottlenecks. NETSCOUT provides visibility into the VDI transports such as Citrix ICA and the interaction of Network and infrastructure components that ICA relies on inclusive of QoS setting, latency, and availability.
Maintain quality performance of applications delivered through the VDI interface. NETSCOUT helps troubleshoot issues across the entire complex service chains in VDI environments from applications tier to the end-user. Additionally, NETSCOUT solutions can automatically and continuously test and collect application performance data from end-user perspective.
VDI performance depends on a well-tuned low latency network. NETSCOUT solutions provide a multi-layered visibility across your entire network inclusive of hop-by-hop QoS setting, wireless, and last mile performance. Flexibility in meeting workforce requirements may require an increased number of configuration changes, which may lead to unintended consequences. NETSCOUT’s real-time network monitoring enhances situational awareness and enables early warning for critical network incidents in both the wired and wireless environments.
Corporate productivity depends on employee productivity. That means those employees must receive the same quality of experience with business applications, whether they are in their corporate office or accessing over VDI remotely. NETSCOUT’s unique combination of real-time monitoring and continuous testing can help organizations meet and surpass their goals for employee experience with visibility into performance of their VDI technologies.
