• Host and deliver apps from centralized virtual machines• Apps run on dedicated Windows XP, Vista or Windows 7 environments• Apps accessed via same method as other XenApp managed apps• Enables Full USB-support and greater app compatibility

• Complementary to server-hosted model• Valuable "niche" option for delivering an app• Apps that won’t run on Terminal Services or need 1:1 environment• Apps that require special devices like USB*, keyboard, biometrics• Apps that consume too many server resources• Potential stop gap while app validation for server-hosting completed• Least TCO efficient of 3 delivery methods (local, server, VM) • Still more cost effective compared to traditional app deployment

• Available in Enterprise and Platinum Edition

• Application runs in virtual machine (Windows XP, Vista, 7)

• App can be delivered to any device (Windows, Mac, Linux, etc.)

• Users consume one license for all app sessions (VM or server hosted)

2. User clicks app icon and Citrix Receiver contacts connection broker

4. User interacts with app remotely. Screen updates, mouse clicks and keystrokes sent between user and server.

XenApp WorkersHosted apps on physical or

virtual PC’s and blades

3. Pooled VM is booted for user. App executes within VM and remote displays to user in seamless mode.


Best Performance. Highest Security.Lowest Total Cost.

End-user experience

1. Server or VM hosted apps appear in the applications tab.

2. Click to connect. Same experience as connecting to server-hosted application.

3. Final release will not show connection bar but display app in seamless mode.

If application VM is suspended, users sees info message and spinner under app icon.

3 ways to deliver any application

Provisioning Services


• Hosted delivery for client-server applications• Requires network connectivity in order to function• Better protection for sensitive data, does not transmit application passwords over the external network• Critical business applications become platform independent (e.g. can be accessed from any OS)• Lowest Total Cost of Ownership

• Local delivery for apps that require offline use• Windows-based, graphics-intensive, multi-media applications• Desktop applications and utilities where offline/disconnected use is required• Easier/faster to maintain than Electronic Software Delivery or traditional app deployment

• VM Hosted delivery for everything else• Benefits of centralized delivery but at a higher cost model (e.g. requires Microsoft VECD license)• For apps that have special device needs, can’t run on terminal services or are resource intensive

• Only Citrix XenApp includes all three

Selecting the best delivery method

Power and Capacity Management


Basics of power management

• Before…• Session sprawl• Low and uneven server utilization• Over-provisioned capacity• Unnecessary power consumption

• After…• Sessions on fewer servers• Optimal server utilization• Just-in-time capacity• Reduced power consumption

e.g. 65% unused capacity, 2 unnecessary servers e.g. 30% unused capacity, 0 unnecessary servers

40,000kWh =* assuming 400W servers

$3600 =*assuming $0.09 per kWh

Provisioning Services


Dynamic Provisioning of Server Workloads

Challenge• Exploding storage cost• High cost with server failures by complex recovery methods• Existing storage infrastructure is not effective enough

Benefits• Fast delivery of new server workloads• Few basis images reduce storage demand• Supports provisioning to XenServer and MS Hyper-V• Also streaming to physical server• Virtualization of server- and device harddisks
