The Benefits of CitrixRunning OTTR in a Citrix Environment
What is Citrix? Citrus Unix Citrix (I’m not kidding!) Citrix is an Application Server––––––Runs an application instance for each logged in userMany users can run an app simultaneouslyAllows remote access to applicationsCan manage printing centrallyHelps control user accessFrees IT staff do other work
How Citrix Works OTTR Runs on the Citrix Server(s) Each session gets their own resources –RAM, CPU, Disk User PC sends keystrokes, mouse clicks Server sends back screen changes ICA Protocol makes it happen
Fairview OTTR Architecture Application Servers– 20 Users per Citrix machine– 3 Production machines Novell Zen Application Distribution Database Servers– SQL Server 2005 SP2 Interface Servers Printers Environments– Production, Test, Dev, Training, Conversion

Benefits Central application administration– Deployment - One place to install & configure– Client workstations can be low-level so equipment life can beextended– Quickly provision new users Server consolidation Application Monitoring and performance– Load balancing Access Control– Remote Access: Citrix Secure Gateway– Manage app utilization
Benefits – cont’d IT staff efficiency – Use staff for otherprojects Application Monitoring and performance Versus MS Windows Terminal Services:– Terminal Services did not have managementtools.– TS did not have server balancing
Even more Benefits Server consolidation through virtualization ICA file deployment easy on our automatedapplication and distribution process
Future Developments Application Virtualization Streaming
