  1. DOIT Training Briefings November 18, 2009 Conference Room 1002 9:30 am What Is Citrix? Presented by Richard May Many of you have heard of “Citrix” but did you ever wonder exactly what it is? Rick will present a high-level introduction to what Citrix is, and what benefits it provides for several of our agency customers. Rick May is an IT Technical Analyst 4 for the Dept of Information Technology, Application Hosting Unit, with over 32 years of IT experience.

  2. What is Citrix ? Many of you have heard the term “Citrix” but do you really know what it means, and what it does for several of our agency customers?

  3. Origins • Founded in 1989 • Citrix was originally named Citrus Systems, Inc. • Changed their name to Citrix when they moved from Texas to Florida.

  4. Citrix Products XenApp – Application delivery system EdgeSight – Server performance monitoring NetScaler – Network Load balancing, and Web Page optimization XenDesktop – Virtual Desktop

  5. Citrix Products These are a few of Citrix’s other products... XenServer – Hypervisor for OS virtualization (Think VMServer) Citrix Password Manager – Single Signon GoToMeeting – Online Meeting solution GoToWebinar – Online webinar presentations GoToAssist – Remote Support Assistance GoToMyPC – Remote access to desktops Access Gateway – Remote SSL VPN Access Concentrator – Optimizes remote office network traffic

  6. What we think of when we say Citrix? • When we speak of Citrix, most of us are thinking about the product formerly referred to as WinFrame, then MetaFrame, then Presentation Server, but now known as XenApp. • XenApp is an application delivery solution. • XenApp works much like the Remote Desktop solution many IT people use to access their servers, and the reason is…. Citrix invented it for Windows NT in 1995.

  7. How does XenApp work? User is authenticated to Active Directory and passes back the users group membership information User Logs into the Citrix Web Interface The Web Interface Server passes the credentials to Active Directory Based on the users Group Membership, XenApp presents the user with applications they are authorized for

  8. How does XenApp work? Application is presented to the end user from the remote server User clicks on an ICON representing the application User logs into the XenApp (Terminal) server In the background The least busy XenApp server is selected (Load Balancing) Users Login scripts are executed Users drives are mapped (C:, P:, etc.) Users printers are mapped

  9. How does XenApp work? Users keyboard typing and mouse movements are transmitted to the Remote XenApp server Only the screen image is transmitted back to the user The result is a significant decrease in traffic between the remote server in the computer room, and the desktop at some distant office

  10. What does XenApp do for me? • Gives the end user a standardized version of all applications. How many offices do you know of that are using multiple versions of Office? • Everybody gets the same patches to their software at the same time. Patching is all done at the servers in the computer room • Enables you to move from desktop to desktop across the state. No matter where you log on to XenApp, you will get all your applications, and have access to all your files. • Enables the you to “Telecommute” from anywhere • In inclement weather conditions • In a disaster situation • When situations call you away from your normal duty site

  11. What does XenApp do for me? • Permits a “temporary” application be assigned to you, and then unassigned to you (freeing up the license) without having to visit your desktop. • Encourages you to store your files on the file server, protecting your work in a stable environment, and providing consistent backups.

  12. What does XenApp do for IT? • Minimizes traffic between the end users desktop and the computer room • By keeping the users files on the file server, data retention, recovery and security are enhanced • Minimizes the need for desktop visits. Applications are installed, configured and patched on the XenApp server not the desktop. • Extends the life-span of the computer. Most of the work is done at the server, and with server resources. • Enables IT to remotely observe any visual issues the user is seeing by “Shadowing” the users sessions (with permission)

  13. Current Enterprise XenApp Users • Currently supporting up to 3800 concurrent users • Dept of Developmental Services (formerly known as DMR) • Dept of Social Services • Dept of Mental Health and Addition Services • Dept of Banking • Office of Consumer Council • Connecticut Siting Council • Office of Workforce Competitiveness • State Board of Accountancy • Emergency Management & Homeland Security (GIS only)

  14. Other State XenApp Users • Dept of Veterans Affairs • 1st State agency to implement a Citrix Product • WinView OS/2 using a 9600 baud modem pool in 1993 • Dept of Insurance – Hosted by the NAIC • Judicial • Dept of Public Health – Also using the XenDesktop product • Dept of Public Works – Hosted by an outside vendor.

  15. Around the Corner • Some new features are being tested with the release of XenApp 5 Feature Pack 2 • Application Streaming – stream the application down to the laptop/desktop based on user credentials permitting off-line use of that application • WorkFlow Studio – Permits the automation of server building, and application installation. • Power & Capacity Planning – permits the automated shutdown and startup of servers based on user needs. • HDX – High Definition User Experience
