- 3. Agenda: • Where weare today • Application Virtualization • ThinApp, App-V • Application Layering • Unidesk, AppVolumes, AppDisks • Demo • Summary
- 4. Where we aretoday Application 1 Application 2 Group Policy System Center Script Deployment tools Base image Shared OS Resources MSVCRT.DLLRegistry File explorer Server VM Template VM Service PXE Boot MDT/System Center Some issues: • Patch management • Application Compability • Application Security • Software dependency • Application testing • Software rot & dll-hell • The big bad image • Application lifecycle management Fixes? • Status Quo • App virtualization • App layering
- 5. Application Virtualization Isolated Application 1 Isolated Application2 Microsoft App-V Vmware ThinApp MSVCRT.DLL Registry File explorer Server VM Template VM Service PXE Boot MDT/System Center MSVCRT.DLL Registry File explorer Shared Resources Some common properties: • Virtual file tree and registry • Includes its own software dependency • Can if allowed in the package read/write to the underlaying OS • Each application is isolated • Can be grouped together • Streaming/Cached
- 6. Application Virtualization Advantages • Noinstall required • Fix application conflicts • No registry and system bloat • Multiple runtime enviroments • Easier update management • Versioning • Improved Security • Easier to do app customization Disadvantages • Bandwidth Requirements • I/O Requirements • More Infrastructure • Cost / Training • Sequencing / Capturing Apps that cannot be virtualized • Device drivers • Boot services • Applications part of the OS • COM+ • Antivirus/firewalls • VPN clients
- 7. Microsoft App-V 5 App-VSequencing machine App-V Management Publishing Reporting Server App-V Database Share Non-persistent SCS Cache Persistent ( RSDH) Testing Pros • Infrastructure or PowerShell • Large support and integration options • App-V license included in RDS CAL! • Large Community • Simple with Office • Many recipies Cons • No support for Internet Explorer sequencing • Requires a client installed on each host • Consumes more disk I/O
- 8. Vmware ThinApp ThinApp Capturing FileRepository AppSync Script/ESD Testing Pros • Does not require any agent • Deployed as reguler exe or MSI • Integrates into existing deployment using MSI • Can virtualize Internet Explorer • Autoupdates within configuration Cons • No central management unless you have Horizon • No PowerShell support • No built-in application usage tracking
- 9. Application Layering Some common properties: •Multiple virtual disks merged • May contain read/write layers • May seperated into application/personal/os layers • Applications behave like normal • Mulitple applications can be placed within the same layer • Write filters and seperating I/O traffic Windows (OS) Application 2 Application 1 (R) Application 3 Personalization (R/W) Layers Machine NTFS/File System Drivers Mini filter driver
- 10. Application Layering Advantages • Simplerapplication «capture» • Delivery application updates • One image! • Works with drivers/services • Can manage personal data* Disadvantages • Some specific hypervisor requirement • No appliation isolation • Yet another solution? Things Apps that cannot be layered • Depending on the vendor..
- 11. Unidesk Windows (OS) Application 2 Application1 (R) Application 3 Personalization (R/W) Layers Terminal Servers/VDI Hypervisor Unidesk Management Applicance Unidesk Cachepoint Windows (OS) Application 2 Application 1 (R) Application 3 Personalization (R/W) Layers Copy layers to the host Collection Installation Machine Advantages • Can layer pretty much everything • Integrated within the Hypervisor • Support for Hyper-V, Azure and ESX • Support for RSDH, XenApp and Horizon Disadvantages • Silverlight based console • No instant app delivery method • Only on virtual machines
- 12. Citrix AppDisks* Application 2 Application1 Application 3 AppDisks Terminal Servers/VDI Hypervisor Desktop Delivery Controller Orchestrate updates Machine Catalog - MCS OS MCS Master Image Personalization layer PVD Preparation Machine Advantages • Integrated into Citrix Studio • Simple management • Can be setup using Citrix MCS or PVS • Can be integrated with either XenServer or ESX Disadvantages • Requires a Citrix enviroment • Virtual Machines only • No Instant-app delivery • Only layering for the applications
- 13. Vmware AppVolumes Non-persistent Constant network connection VHD-In-guest mode AppStack AppStack Writeable Volume AppVolumes Terminal Servers/VDI Hypervisor AppVolumes Manager Assign resources Provisioning Machine AppVolumes Agent AppVolumes Agent AppVolumes Agent Advantages • HTML5 based management • Instant-app delivery* • Physical and virtual delivery • Simple to setup • Writeable layers Disadvantages • Only ESX hypervisor support • Wierd requirements for physical devices

- 15. Summary (When touse what) Application virtualization: Pros: • Isolated applications • Flexible delivery methods • Application Compability fixes • Multiple runtime applications Application layering: Pros: • Simple capturing process • Can include profile management • Makes application lifecycle simpler Moving forward • Project Centennial • App-Containers

Editor's Notes
- #15 Showing and regular machine with adobe reader installed and try to install a new version….. Showing a simple application capturing on app-v and thinapp Showing deployment of app-v using regular setup and SCS on App-V using multiple adobe reader versions Showing I/O and network traffic Showing rollout of ThinApp and auto updates using adobe reader Showing Internet explorer virtualized using ThinApp Showing setup of application layering on appvolumes and and capturing process. Show management and setup an application layering process (App volumes) Show on how to attach and application layering at boot (Appvolumes) Show how to attach an writeable volume to an machine (Appvolumes) Show on how to create an collection of RSDH hosts using different layers in Unidesk management Show how they merge on a virtual machine in Hyper-V manager Login to the virtual machine Add another applicaiton layer, reboot and notice the application
- #17 Bruke Client performance analyzer for å verifisere at det er en bra connection mot miljøet. Lage en configurasjonsfil for å laste ned office og innstallere med shared computer support (bruk eksisterende configurasjonsfil for å innstallere Office-pakken, UTEN OneDrive) mens den driver å laste inn, bruk tiden til å legge inn Office2016 Group Policy ADMX templates. Når den er ferdig start den. Prøv deretter å innstallere 32-bits, vis at det ikke funker. Visst hvordan vi lager en app-v pakke i 32-bits, start den via App-V) Vis hvilken versjon av Office som ligger der. Start Office365 Pro Plus, vis at shared computer support ikke er aktivert, legg inn reg nøkkel for å fikse det. Vis at det ikke er noen produktnøkkel i imaget via cscript.exe "%programfiles%\Microsoft Office\Office15\ospp.vbs" /dstatus) Authentiser og vis at tokenet blir generert i Lokal. Start Skype for Buisness via RDP start video samtale via andre Pcen. Se på ytelsen som blir startet….Logg av. Start Skype for Buisness via Citrix ICA, logg på Skype for Buisness. Start Video samtale på nytt, vis ytelsen på CPU og minne i sesjonen samt via i Performance monitor at traffiken går lokalt..
