Top 10 Benefits of a GIS Citrix Farm1. Guarantee best performance – Good corporate LAN “citizen”

• Enables remote GIS users to access GIS desktop system across slower WAN connections• Smaller footprint for GIS desktop users on faster Corporate LAN

– (GIS fat-client comparable to Video Conference footprint on corporate network)• Even possible to connect over 56K dial-up connections

2. More stable across WAN connections (latency tolerant)• Application can disconnect and then reconnect without losing Citrix session• Less affected by latency issues across WAN

3. Lower cost for hardware requirements and system administration• No need for costly high-end workstations for each GIS user

4. Easy to scale over time5. Centralized management / configuration of Client GIS software6. Easier detection and resolution of software bugs and performance issues7. Easier to distribute upgrades or bug fixes8. Faster turn-a-round for development & QA integration testing of custom GIS

extensions: • Development Test Production

9. Any authorized GIS user can access all three environments at the same time from their local workstation

10. Remote Monitoring/Control - Shadowing

How Many Concurrent GIS Users Can a XenApp Server Support?32-bit vs. 64-bit Windows Server OS

32-bit Windows Server OS10-20 GIS users 2 core server w/ 4 GB RAM

30-40 GIS users 4 core server w/ 16 GB RAM(using Enterprise version of Windows Server OS & /PAE switch)

64-bit Windows Server OS (Requires 64-bit Drivers)

40-60+ GIS users 8 core server w/ 32 GB RAM80+ GIS users 16 core server w/ 64 GB RAM

Today’s Intel & AMD based servers are so fast and powerful that the primary hardware issue for Citrix servers

is the amount of Memory not CPU capacity or speed.
