7 Application Streaming

8 Client-side Application Virtualization Overview 1. Applications profiled using installer and profiler tool, then stored in App Hub 2. User logs in and the XML service on the XenApp Server is used to enumerate the icons 3. User clicks on the application icon to and client contacts XML service to build the RAD file that contains the properties for how to connect to the Application HUB Application Hub 4. Application is streamed and executed Profiler XML Service (on XenApp Server) Client 8

9 Components Existing Infrastructure Profiler File Servers Access Management Console License Server Client Device Hosted Apps Streamed Apps XenApp Web UI XenApp Server IMA Data Store 9

10 Isolated Execution Layers Profiler Machine Two Layers: Installation layer and the Machine layer Read/Write Target Machine Three Layers: User Layer, Installation layer, Machine layer Read/Write Installation/Execution Image Per User Image Read Only Read Only Install program, registry, named Machine objects etc. stored in.cab file Nothing gets written to this layer at profile time when the application is installed The installation program is painted on this pane of glass File redirection Installation/Execution Image Machine Execution image common to all users enables centralized app management User changes are written to Per User Image 10

11 What is in a Profile Package Profile Can consist of one application or multiple applications that need to communicate with each other Single set of Icons and Apps Target Isolation Environment where application is run Multiple targets can exist within one profile OS, Boot Drive, and Language differentiate the targets Streaming Client determines appropriate target to build based on the client machine OS, Boot Drive and Language 11

12 The Profile Package.profile file Targets (cab files) Targets are uniquely identified by a GUID One.cab file for each Target in a Profile 12

13 Target Properties Defined By Operating System Boot Drive Language Isolation Rules 13

14 Isolated Execution Layers Execution Layer Application Files Application Registry Execution Layer Application Files Application Registry Data System Environment Machine Machine 14

15 Isolated File System Virtual path: Adobe 9: C:\Program Files\Adobe Physical path: Adobe 9: C:\Program Files\Citrix\RadeCache\ae357acb aad9-d6e794a55ca8_1\Device\C\Program Cache Location on the Target Target ID - GUID Application files 15

16 Isolated Registry - Location HKLM\Software\Citrix\RadeCache\43eedfd1-bcd4-4cbf c10ff5b900_1\... Application Registries 16

17 File System In Action C: Windows Program Files My App The streamed application thinks it is running in C:\Program Files\My App. C: Windows Program Files My App The streamed, application files are stored in local cache. MyApp.EXE MyApp.INI UserConfig.INI Citrix RadeCache GUID Device C Program Files My App MyApp.EXE MyApp.INI UserConfig.INI Virtual File System Physical File System 17

18 File System In Action C: Windows Program Files My App MyApp.EXE MyApp.INI UserConfig.INI %HomeDrive% AppData Application still believes file is in application folder Roaming Citrix RadeCache GUID Device C Program Files My App UserConfig.INI If file is opened for Write access, it is copied to user layer C: Windows Program Files My App Citrix RadeCache GUID Device C Program Files My App MyApp.EXE MyApp.INI UserConfig.INI Virtual File System User Layer Physical File System 18

19 Read/Write Redirection Application layer is read-only (file and registry) Changes made to application layer redirected within the user layer: File: %HomeDrive%\AppData\Roaming\Citrix\RadeCache\ GUID\Device\C\... Registry: HKCU\Software\Citrix\RadeCache\GUID\Registry\ Machine\Software\... User Files User Registry User Layer (User 2) Application Files Application Registry Execution Layer Data System Environment Machine 19

20 Network Optional XenApp Server Application Hub Deployment Cache Remote User 20

21 Network NOT Required Users continue to launch applications from Start Menu C: Windows Program Files My App Citrix Deploy Office 2007 Adobe RadeCache GUID GUID.CAB Office.profile Device C Physical File System (Laptop) Offline-defined application profiles copied into local Deploy folder on physical device Application launch streams bits from Deploy folder (local Application Hub) 21

22 Updating Profiled Applications Run the Profiler Wizard and update the application Save the profile updates to the file server Next execution, user receives updates 22

23 Updating Profiled Applications Live! User Layer User Files User Registry %APPDATA%\Citrix\RadeCache\GUID (notice no version) Execution Layer Application Files Application Registry C:\Program Files\Citrix\RadeCache\43eedfd1 bcd4 4cbf c10ff5b900_1\ Device\C\Program Files\... Application is updated Machine Data System Environment C:\Program Files\Citrix\RadeCache\43eedfd1 bcd4 4cbf c10ff5b900_2 \Device\C\Program Files\... Guid remains unchanged The version is updated 23

24 Design Considerations

25 Branch Offices Application profiles can be GB in size Offline users must cache the entire profile to local device Multiple users over a single WAN connection to a branch office Consumes WAN bandwidth Slow caching Disrupts other business 25

26 Branch Offices Application Hub XenApp Server Client Branch Repeater WAN Repeater 26

27 Application Conflicts Unknown end-user device XenApp delivered applications cannot break device Machine layer contains userinstalled applications Streamed applications are isolated from machine layer Execution Layer Machine Layer IT-Delivered Application 1 Windows User App 1 Execution Layer IT Delivered Application 2 User App 3 User App 2 27

28 Application Corruption Disconnected users cannot get files in event of deletion/corruption Corrupted or deleted files C: Windows Program Files My App Citrix Deploy Office 2007 Adobe RadeCache GUID GUID.CAB Office.profile Device C Re-Streamed from local deploy folder Physical File System (Laptop) 28

29 Application Updates Previously, updated offline apps required a full re-download of the profile With Streaming 1.2 Only new application files sent to client New files combine with old profile in Deploy folder and an updated profile is reconstructed Profile contents on file share and client are identical Temporarily trades client-side CPU for significantly lower bandwidth usage (e.g. 1.4GB profile vs. 100MB update) DELTA ONLY PC with Citrix Applications client Old profile in Deploy folder Uncompress New files from updated profile Updated Old profile Profile on on UNC Share Application Hub (File Server) Updated Profile in Deploy folder Combine and recompress RADE Cache on Server XenApp Farm (Server-side App Virtualization) Stream on-demand to RADE Cache folder on Client 29

35 Application Streaming Streaming implementation using the SMB protocol Profiler copies package to file share XenApp points to UNC path of file share during application publishing Target contacts the file share during streaming Protocol used in all instances is SMB Limitations of SMB: Not WAN friendly Communication not secure Client SMB Publish XenApp Web & XenApp Service site Profiler XenApp Servers File Share SMB application Profiling SMB Profiler 35

36 Application Streaming Streaming implementation using the HTTP(S) protocol Profiler copies package to file share XenApp points to the URL of profile located on a web server during application publishing Publish XenApp Web & XenApp Service site Profiles can be streamed from a web server XenApp Servers Target contacts the web server during streaming Streaming protocol is HTTP(S), which is faster and more secure SMB streaming is still supported Client HTTP(S) HTTP(S) Web Server File Share Profiler File Share SMB Profiler 36

37 New OS? No Problem!

38 Target Properties Defined By Operating System Boot Drive Language Isolation Rules Citrix Systems, Inc. All rights reserved 38

39 Single Profile Multiple Targets MS Office.profile Standard Base OS Images Streaming Client Target 1 WinXP Target 2 Windows 7 Target 3 XP-German Windows XP Windows 7 German Windows XP File Server Citrix Systems, Inc. All rights reserved 39

40 New Operating System Install Windows 7 (20-30 minutes) Install Citrix Receiver (1-2 minutes) Receive XenApp-delivered applications (x minutes) 40

41 Next Steps

42 Getting Started Assess application/user needs Identify risks with enabling offline Bandwidth Security Storage Create an assessment plan and test In house testing with XenApp Evaluation Virtual Appliance (EVA) ( Cloud testing with XenApp in the Amazon cloud ( 42
