Hosted Application Delivery and FeaturesHosted application delivery is the process of delivering applications to users by firsthosting them on centralized servers in the data center, and then remotely displaying orpresenting them to user devices. Presentation virtualization occurs when the userconnects to the hosting server and the application is remotely displayed on their devicein a seamless fashion.

The following sections briefly describe the XenApp features that help facilitate hostedapplication delivery. See the Citrix XenApp Administrator's Guide for more informationabout each feature, unless otherwise noted.

Load ManagementUse Load Manager to set up, monitor, and balance the server and published applicationloads in a server farm so that users can run the published applications they needquickly and efficiently.

The criteria you define in Load Manager determine which servers are least busy and canbest run an application. When users launch published resources, Load Manager selectsthe server that runs the application or desktop session, based on server load. LoadManager ensures that each new session request is forwarded to a server that is notoverloaded, thus improving the user experience. For more information, see the LoadManager Administrator’s Guide.

Preferential Load BalancingPreferential Load Balancing provides preferential treatment for users and applications.This feature enables you to prioritize a user group and applications based on pre-established priorities. Use Preferential Load Balancing to assign higher or lower levelsof XenApp service to specific users, groups, and applications.

Users and applications with higher priorities and levels of service connect to theirXenApp sessions more quickly, experience more interactive ICA sessions, and have morecomputing resources available to them.

CPU Utilization ManagementCPU utilization management improves the ability of a farm or server to manageresources and normalize CPU peaks when performance becomes limited by CPU-intensive operations (Enterprise and Platinum Editions only). Depending on yourXenApp edition, you can enable Fair Sharing or Preferential Load Balancing.

Resource ManagementFor the XenApp Enterprise Edition, a new Resource Manager improves monitoring andreporting capabilities with session-level performance counters, multivariable alertcapabilities, a vast library of pre-configured and customizable reports, and integrationwith Health Assistant.

To locate the EdgeSight documentation needed to transition to this release of ResourceManager, see Finding EdgeSight Documentation.

Chapter 3 XenApp Feature Overview

18

Health AssistantThe Health Monitoring and Recovery service monitors the health of many XenAppfeatures and reports failures. You can configure this utility to stop accepting newconnections or take the server offline if it detects a problem, thereby optimizing the end-user experience.

SNMP MonitoringXenApp supports Simple Network Management Protocol (SNMP) monitoring andintegration with third-party SNMP network management products. Via this support, third-party applications can monitor server status, terminate processes on servers,disconnect, logoff, or send messages to users, and query server activity.

The XenApp administrator enables SNMP monitoring on the XenApp servers, andindicates the traps to be monitored.

XenApp Provider and XenApp Management PackWorking together, the XenApp Provider for Microsoft Windows ManagementInstrumentation (XenApp Provider) and the XenApp Management Pack for MicrosoftOperations Manager and System Center Operations Manager (XenApp Management Pack)enable you to monitor the health and availability of farms running XenApp Enterpriseand Platinum Editions. This feature enables integration with Microsoft monitoring toolsto anticipate and react quickly to any problems.

To learn more, see the Provider for Microsoft WMI Administrator’s Guide, ManagementPack 2007 Administrator’s Guide, and Management Pack 2005 Administrator’s Guide.

Application StreamingApplication streaming centralizes the management of desktop applications and isolatesand streams them to users without application and system conflicts. When you publishapplications for streaming to client desktops, users access the application from the fileshare or Web server and stream it to their client device. Streamed applications arecached on the local client device and run within an isolation environment, whichprevents conflicts with locally installed applications. You must prepare applications forstreaming using the Streaming Profiler.

Application streaming provides the following benefits:

w Applications run on the local Windows client device. Streamed applications canuse system resources on the client device, not the XenApp server.

w Update applications centrally. Deliver upgrades or patches efficiently andseamlessly to client devices the next time they access the application.

w Isolation environments. Run applications within protected isolation environmentson client devices, which prevents conflicts with other applications installed locally.

w Application caching. Configure the option for caching files on the client device toallow faster access the next time the application is launched.


19

w Dual-mode streaming. Configure a fall-back method for application delivery in caseclient devices do not support streaming.

w Offline access. Allow users to continue running streamed applications afterdisconnecting from the network.

For information about using application streaming, see the Application StreamingGuide.

Local desktop (offline) use of the Application streaming feature is available to allXenApp users who access hosted applications. This allows XenApp users to streamapplications to the desktop without requiring a separate license.

Important: Your use of Application streaming to end-user devices (or clients ormachines) included with the Advanced, Enterprise, and Platinum Editions of XenApp islimited to support users of XenApp hosted applications, and not other users.

Citrix ReceiverCitrix Receiver provides a simple way for users to download and install Citrix plug-ins,and then access their applications from anywhere. It invisibly manages updates to theCitrix plug-in family on the user's desktop and consolidates Citrix notifications anddesktop icons.

Citrix Receiver comprises the Receiver application that resides on the end user’scomputer, the Update Server that resides in your data center, and the Citrix UpdateService that resides on a Citrix Web site.

Citrix Receiver simplifies application access and management for end users andadministrators by providing the following features:

w No end user setup or configuration. Users install the Receiver on their computer.When installation is complete, the Receiver installs all of the applications scheduledby the IT administrator, without requiring the user to enter any information.Upgrades to the Receiver software are handled the same way.

w Ease of operation. The Receiver starts when users start their computer. On startup,the Receiver evaluates its managed applications and starts them in the correctorder, ensuring a secure connection before starting applications which rely on it.(Users who want to customize their configuration can access the applicationinterfaces through the Receiver Control Panel.)

w Invisible operation. The Receiver silently handles application upgrades andinstallation. If a download is interrupted, the Receiver silently resumes the actionwhen the connection is restored.

w Simplified administration. Citrix Receiver enables administrators to deliverapplications and application plug-ins to all end users at once without performingrepetitive deployments. The Update Server retrieves application updates from theCitrix Update Service and presents the update list to the administrator. Theadministrator then downloads the updates, performs standard file testing, anddelivers the new updates to users.


20

w Polls the Citrix Update Service for application updates and presents them to theadministrator.

w Retrieves user and group information from the corporate Active Directory and loadsthem into its database. This data is then used to authenticate users and populatethe lists that designate delivery recipients, retrieve user log files, and manage userpermissions.

w Creates token licenses for user authentication to ensure security while minimizinginterruptions to the end user.

w Broadcasts application installers to the users and groups according to theconfiguration and schedule you define.

w Uses HTTPS for transport to provide secure connections for data transfer protection.

XenServer Virtualization PlatformThe Citrix XenServer virtualization platform provides open, powerful servervirtualization that reduces datacenter costs by transforming static and complexdatacenter environments into more dynamic, easy to manage server workload deliverycenters. Based on the open source Xen hypervisor, XenServer delivers a secure andmature server virtualization platform with near bare-metal performance.

To learn more about XenServer, see the Citrix web site.

Load Testing ServicesThe Load testing services feature provides an efficient and cost effective method ofserver sizing and application load testing for XenApp environments. By simulatinghundreds of virtual Citrix users and monitoring the responsiveness of the system undertest, it allows the administrator to determine how the current configuration andhardware infrastructure will support anticipated demand.

This load generating software solution enables XenApp administrators to:

w Predict how systems will cope with high levels of user load

w Deliver tried and tested application virtualization environments by simulatingthousands of users to identify system bottlenecks or application instability beforesystems go live

w Reduce costs associated with change management and application regressiontesting; reusable scripts simplify before and after comparison following applicationpatches or operating system updates

w Assess new hardware; understand the capacity limits of different hardware types tomake informed purchasing decisions

w Perform branch office application performance testing; create real traffic fromremote sites, ensuring bandwidth and server resources are available to deliver thebest user experience

Provisioning ServicesThe Provisioning services feature reduces total cost of ownership and improves bothmanageability and business agility by virtualizing the workload of a datacenter server –operating system, applications streaming server workloads on demand to physical orvirtual servers in the network.

By delivering server workloads on demand rather than deploying them on individualservers, the Provisioning services feature:

w Simplifies and streamlines server management, and reduces software rollout risk

w Delivers the operating system, applications, and server configuration information ina real time stream, maximizing performance and minimizing network load

w Assures server consistency by provisioning servers simultaneously from a singlestandard image

w Increases IT responsiveness and agility by enabling capacity on demand; repurposeany server to do any job

w Reduces utility costs and space needs by lowering the number of backup serversneeded to support disaster recovery and business continuity

w Risk-free server workload rollout - rollback to a previous working image in the timeit takes to reboot

w Built-in support for redundant servers, networks, and databases

For documentation information, see http://support.citrix.com/product/provsvr/psv5.0/#tab-doc.

Important: Your use of the Provisioning services feature included with the PlatinumEdition of XenApp is limited to provisioning only XenApp Platinum Edition workloads.(You can use XenServer Platinum edition (purchased separately) to provision non-coreXenApp Platinum servers.)

Profile ManagementThe Profile management feature provides an easy, reliable way for managing userpersonalization settings. Profile management saves these settings during logoff to theuser store for each user. If the file already exists (the most common case), the changesfrom the current session are merged with the existing settings.

At logon, if a locally cached profile exists, the two sets are synchronized.

XenApp Platinum DeploymentCitrix XenApp Platinum Edition offers a comprehensive solution to instantly deliverWindows applications to users anywhere, with enhanced security features and powerfultools that enable greater control and visibility of even the most complex environments.

This diagram shows how many of the XenApp Platinum Edition features can helpincrease IT responsiveness and agility.

Using XenApp to Manage ApplicationsPreparing and Publishing ApplicationsWith XenApp, you can deliver:

w Streamed applications installed in application profiles and stored on a file server.Users access the profile and virtualize the applications on their client desktops.

w Applications installed on servers running XenApp. When users access them, thepublished applications appear to be running locally on client devices.

w Data files such as Web pages, documents, media files, spreadsheets, and URLs. InXenApp, the combined total of data types you publish is referred to as content.

w Server desktops that Publish the entire Windows desktop of a server in the farm.

To use the application streaming feature, you package applications into profiles. Aprofile contains one or more targets (a collection of disk files, registry data, and other

Chapter 4 Getting Up and Running with XenApp 5

28

information that represents an application isolation environment), plus the metadataneeded to stream the profiled applications. Each target specifies a combination ofoperating system, service pack level, system drive letter, and language. A profile cancontain one or more applications; for example, a single profile can contain MicrosoftWord or the entire Microsoft Office suite. See the Citrix Application Streaming Guidefor details.

When you publish an application, configuration information for the application is storedin the data store for the server farm. Configuration information includes the types offiles associated with the application, users who can connect to the application, and theimportance level for load balancing.

See the Citrix XenApp Administrator's Guide for complete information about managingdelivery options for published resources, managing application properties, using virtualIP addresses, and using the Publish Application wizard.

Accessing ApplicationsCitrix offers a variety of options for accessing applications. Additionally, you cancustomize the user environments, as well as manage and optimize sessions.

w Citrix Receiver for Windows. Citrix Receiver provides a simple way to download,install, and update Citrix plug-ins. For more information, see Citrix Receiver on page20.

w Web Interface. The Web Interface can be used to create stand-alone Web sites foraccess to published resources that you integrate into your corporate portal. TheWeb Interface queries the server farms and dynamically creates an HTML page thatcan be viewed with a Web browser. After logging on, users are presented with acustomized Web page containing a list of the published resources that you makeavailable to them. For more information, see the Web Interface Administrator'sGuide.

w Citrix plug-ins. Citrix offers plug-ins for a wide range of client devices andplatforms for access to hosted applications. Application streaming also has its ownplug-in. You can use Citrix Receiver to manage several of these plug-ins; you canalso manage plug-ins individually. For more information about plug-ins, see theClient Downloads section of the Citrix Web site.

You can customize the user environment through client-side session managementproperties such as window size, number of colors, encryption level, and audio setting.To further refine how users launch and access published resources, you can use contentredirection and XenApp policies. For session management information, see the CitrixXenApp Administrator's Guide.

Application EnhancementsXenApp offers a variety of features that complement and enhance application delivery.For details, see XenApp Feature Overview on page 17.


29

Preparing to Create the FarmBefore you install XenApp, prepare the servers and install the preliminary componentsso that the XenApp installation wizard can reference them.

1. Citrix recommends installing Citrix XenApp on a fresh installation of WindowsServer 2008. In particular, uninstall any XenApp components and Citrix LicenseServer from early releases, including the Beta and Release Preview.

2. Configure Windows Server 2008 for XenApp 5. See the Citrix XenApp InstallationGuide and the Citrix XenApp Installation Checklist for details.

3. Install the system prerequisites on all XenApp servers. See the Citrix XenAppInstallation Checklist for details.

4. Install Certificate Services. Obtain the necessary certificates. Certificate Servicesissues and manages SSL certificates within the domain to which the servers belong.A certificate is required for use with the XenApp Single sign-on feature. As a bestpractice, isolate evaluation systems from your production network environment.For example, install an isolated Certificate Authority on the domain controller.

5. Install Citrix Licensing.

6. Install and configure the Web Interface. Install and configure this feature on oneserver in the farm. For details, see the Web Interface Administrator’s Guide.

7. Install and deploy the XenApp Plug-ins for Hosted Apps and StreamedApps.Whether as part of Setup or separately, you must install, at a minimum, theclient engine, which is included in the Clients\ica32\XenAppWeb.exe, whichprovides the function for pass-through client authentication.To stream applications from any server, even if you are not streaming applicationson this server, you must install the XenApp Plug-in for Streamed Apps. For details,see the XenApp Plugin for Hosted Apps Administrator’s Guide and the ApplicationStreaming Guide.

w Citrix Licensing (if enabled on the Component Selection page)

w Pass-through authentication

w Access Management Console

w Web Interface (reference the preconfigured site or accept the default)

w XenApp Plugins

w XenApp farm

w XenApp Advanced Configuration

w Documentation

Citrix strongly recommends that you review the Setup instructions for thesecomponents in their respective administrator’s guides before attempting theirinstallation.

After installing XenApp and deploying your farm, continue by installing the additionalcomponents required for your organization.

Installing Additional FeaturesThe XenApp editions license some or all of the following additional features. Do notinstall XenApp features on a domain controller.


31

Note: The following list includes high-level installation information; it is notcomprehensive. Use the feature's documentation for installation guidance.

w Application streaming. On a separate, clean workstation with an operating systemsimilar to that of your end-users, install the Citrix Streaming Profiler and use thisworkstation to profile applications for streaming.

w Single sign-on. Before installing the Password Manager plug-in from a commandprompt onto a Windows Vista or Windows Server 2008 computer, install the MicrosoftVisual C++ 2005 SP1 Redistributable Pack (x86) and Microsoft Visual C++ 2005 SP1Redistributable Pack (x64), available from the installation media in the Support/vcredist directory.

w SmartAuditor. Install the SmartAuditor player on a Windows Vista or Windows XPdevice only. The SmartAuditor Server and database cannot be installed on WindowsServer 2008. As a best practice, do not install the SmartAuditor Server and databaseon the same server as XenApp.

w Application performance monitoring. Install this feature on a separate server. Toavoid errors in performance measurement, do not install the Applicationperformance monitoring database on any farm servers that will be hosting usersessions.

w EasyCall voice services. Install the EasyCall plugin and configure the EasyCallappliance using documentation provided with the appliance (purchased separately).Install the EasyCall plug-in on every XenApp 5 server or client device as required.

w Secure application access. Depending on your Access Gateway edition, you caninstall the plug-in from the appliance (purchased separately).

w WANScaler. Install the WANScaler plug-in provided with this release and install andconfigure the WANScaler appliance using documentation provided with theappliance (purchased separately). The Branch optimization feature does notfunction with Access Gateway Enterprise Edition.

For installation information about the XenApp 5 Feature Pack, see CTX120239 or theRelease Notes for XenApp 5 Feature Pack in eDocs.

Running Mixed FarmsBecause Citrix XenApp 5 for Windows Server 2008 runs on a different operating systemfrom Presentation Server 4.5 with Feature Pack 1, upgrading farm servers automaticallyby using the Setup wizard is not supported.

If your farm is running Presentation Server 4.5 with Feature Pack 1, you can migratesome of your farm settings. Otherwise, you must transfer them to the new farm manually.

Before starting your installation, refer to the information about migration in the CitrixXenApp Installation Guide.

When you run multiple versions of XenApp and Presentation Server in your farm, this isknown as a mixed farm. A mixed farm could, for example, have some XenApp 5 serversand other servers running Presentation Server 4.5 with Feature Pack 1. Mixed farms


32


have special considerations ranging from the version of administrative consolessupported to what functionality is available on specific servers or throughout the farm.

Citrix recommends not having a mixture of XenApp and Presentation Server versions ina farm. However, there are two situations when you may want to run a XenApp farmwith different versions of Presentation Server:

w You want to migrate your farm servers over to the latest release gradually. Forexample, you may not have the time to migrate all of your servers immediately, soyou plan to migrate them gradually over a period of several days.

w You require a feature not supported in this release of XenApp. For example, if yourequire PDA sync, you may need at least one computer with Presentation Server 4.5with Feature Pack 1 in the farm to support this feature.

For XenApp 5, Citrix supports mixed farms only with Presentation Server 4.5 withFeature Pack 1. However, Citrix recommends keeping all servers in the same farm atthe same product version level.

An alternative to running a mixed farm for an extended period of time is to create twodistinct farms and use the Web Interface to provide users with a centralized access tothese farms.

Getting the XenApp 5 Feature PackFor information about getting the XenApp 5 Feature Pack, see CTX120239 or theRelease Notes for XenApp 5.0 Feature Pack in eDocs.
