Disclaimers1. NOT an overview session2. NOT a sales pitch3. No, I do NOT have an answer to all scenarios (yet).
Agenda• Vision behind the app model• The app model overview in record time• User device affinity• Content library• Application Supersedence• Application Uninstalls• Challenges and potential workarounds• Troubleshooting & Monitoring• Questions?
Vision behind the app model Lifecycle • Install • Upgrade • Uninstall management • • Retire Versioning and history User centric • Deliver applications to users not computers deployment
Vision behind the app model Application Installation Application Uninstall Application Revision Application Retirement Application Supersedence
Requirement Rules in 2012State-based Application Management Properties of users and/or devices that Rules are per Evaluated in real- makes delivering deployment type time on the clientsoftware appropriate Evaluated before content is Re-evaluated on a downloaded to the schedule client
Detection MethodsState-based Application ManagementDetection is the key to any state based softwaredistribution system Detection methods enable systems to determine whether or not an application is already present on a system (Discovery) Detection methods are also used to determine the success or failure of a deployment Important to get these right!
Application Supersedence But, Allows admins to Definition: The ability for testpilot newer the admin to create a This ultimately results in the application, prior to relationship and declare newer application replacing production release. Whileone application newer than the older application for a permitting the older another previous user on a device application to continue to application. exist for the majority of users
Supersedence and the end-user UX User only sees latest application version in Software Catalog (by default) Required applications are always the enterprise’s latest version. When the user or computer receives a policy that targets it with BOTH policies Available Applications installed by user can be automatically updated
Supersedence examples (1) SimpleScenario and Assumptions 2 applications: Adobe Reader X supersedes Adobe Reader 9 Both applications deployed to same deviceIf client has Adobe Reader 9 alreadyinstalled assuming requirements are met for Reader X, Reader 9 will be replaced with Reader X (either uninstalled or updated)If client has Adobe Reader X alreadyinstalled evaluates both 9 and X detection methods, X is present, 9 is not – but since X supersedes, it doesn’t try to install 9If neither are installed, only AdobeReader X will be installed
Supersedence examples (2) Conflict 2 applications: Adobe Reader X supersedes Adobe Reader 9 Accounting App (AA1) depends on Reader 9Case 1: Client receives all policies No applications have been previously installed Assuming requirements for all Deployment Types are met, Reader X will be installed on device AA1 is not installed on client, and conflict requirements not met messageCase 2: AA1 policy received prior to supersedence relationship defined. AA1 and Reader 9 will be installed (assuming requirements are met), When Reader X is deployed, a conflict for Reader X will be provided to user and admin
Application Uninstalls • Uninstall is a deployment action Admin creates an Uninstall Deployment • The App Model defines an uninstall method for each Deployment Type of an Application.An admin defines a specific collectionto target the Uninstall Deployment to (either users or machines)If a user or device is the recipient of both an install and uninstallpolicy, then install wins and the app will not be removed
Troubleshooting & monitoring The deployment What logfiles? monitoring tool
Sharing our experiences / challengesApplications installed User targeted installs Application Uninstallsduring a tasksequence Roaming user logging and computer targeted do not validate the generate an install in to my workstation uninstalls requirements policy
Challenges and potential workarounds Required app to Automatically user on primary Required appv with upgrade available device, available on roaming profiles applications non-primary Uninstall an application from a machine that is still targetted to users
