What Is VDI? Key deployment scenarios of VDI are persistent virtual machines and pooled virtual machines VDI: • Centralizes the storage, execution, and management of Windows desktops • Stores and maintains the user work area in the data center • Enables technologies such as Hyper-V and Remote Desktop Services
Key Benefits of VDI • Improved access to data and applications from any device • Improved data security and compliance • Simplified management and deployment of applications • Improved business continuity • Integrated management of physical, virtual, and session-based desktops • Centralized data storage and backup
Types of VDI Personal virtual desktops Each virtual machine is like a traditional personal computer, where user data, settings, applications, and operating systems are stored, and each user is assigned a personal virtual desktop. Pooled virtual desktops Identically configured virtual machines are in the pool and users can connect to any virtual machine. After users log off, all changes are discarded, so user data must be stored outside the virtual machine.
VDI Components in Windows Server 2008 R2 • Active Directory • Remote Desktop Web Access • Remote Desktop Connection Broker • Remote Desktop Virtualization Host • Remote Desktop Session Host • Remote Desktop Gateway
RD Connection Broker in VDI Deployments RD Connection Broker enables user connections to connect to an appropriate endpoint Brokering involves: • Identifying a virtual machine for the user • Preparing the virtual machine for remote connection • Sending virtual machine details to a session host server • Monitoring user sessions in a virtual desktop pool scenario
Configuring Virtual Machines Supported operating systems: • Windows XP • Windows Vista • Windows 7 Configuring virtual machines for virtual desktops: • Joins virtual machines to the domain • Configures the Remote Desktop functionality by: • Enabling RDP and RPC for RDS • Adding VDI users to Remote Desktop Users group • Configuring Windows Firewall
What Is Application Virtualization? Application virtualization allows you to run applications on client computers as if they were installed locally Benefits of application virtualization are: Centralized management Scalable infrastructure Accessible applications Remote Desktop Server support Reduced license compliance risks Usage reporting
Run applications as a “service” • Access anywhere • Over the web • Portable devices • Just in time deployment (Click-to-Run) • Installer does not run • Instant gratification • Simple servicing • Update once, deliver everywhere • Users automatically stay up to date
Run applications without conflicts • No changes to system • Safely run apps side-by-side • No OS decay over time • Lower migration costs • State separation • Store App state separate from OS state • State categorized as user versus system • User state stored in profile, roams with profile
How Does It Work? • App packaged using Sequencer • Installation monitored to capture resources • All app resources stored in an app image (.SFT) • App image placed on server for distribution • App streamed to client over network • SMB, HTTP(S), RTSP(S) • Can leverage DFSR replica and BranchCache • Other distribution mechanisms possible (USB) • App-V runs app in Virtual Environment (VE) • App virtualization layer handles resource requests
Use Microsoft Application Virtualization to stream applications on-demand • Advantages: • Centralized application management • Support for roaming users and making applications available quickly • Can run multiple versions of Office on the desktop • Previously incompatible applications can run on the same desktop • Centralized image simplifies updates, management & helpdesk • Limitations: • Requires a supporting infrastructure and resources • Consider network bandwidth availability for streaming applications • Integration into existing infrastructure, such as the patch management process
What Is App-V Desktop Client? Application Virtualization Management Server Network Application Virtualization Desktop Client • Requests applications to be streamed • Receives the application code • Sets up the runtime environment • Executes the code locally
App-V 4.6 Shared Cache for VDI environments • In Microsoft Application Virtualization (App-V) 4.6 the Client supports using a shared read-only cache • Shared read-only cache enables the Client to use disk space efficiently in a Virtual Desktop Infrastructure (VDI) system • You can deploy the App-V Client in a VDI scenario by using a shared read-only cache that has been populated with all the applications required for all users. http://technet.microsoft.com/en-us/library/ee956915.aspx
What Is RDS? RDS is presentation virtualization technology that provides access to session-based desktops, virtual machine–based desktops, and applications • RDS provides the following benefits: • Run an application or an entire desktop on centralized servers • Manage session-based desktops, applications, or virtual machine–based desktops on centralized servers • Provide an entire desktop, or just application window • Provide integration of local and RemoteApp programs • Enable secure remote access without establishing a VPN connection • Centrally control which RD Session hosts can be accessed, who can access them, and device redirection

What Is the App-V Client for Remote Desktops? The App-V Remote Desktop Client: • Uses a separate installer from the Desktop client • Requires putting the Remote Desktop server into install mode to install the client App-v Management Server LAN App-V Remote Desktop Client Remote Desktop Server Network LAN, VPN, Internet Client Computer
What Are RemoteApp Programs? RemoteApp programs run remotely on RD Session Host server and can integrate with locally running programs A RemoteApp program: • Can be accessed remotely through Remote Desktop Connection • Displays on the client as if it is running on the local computer • Has its own resizable window and entry on the taskbar • Can run along with local programs on the client computer • Can share a RD session with another RemoteApp program on the same terminal server
What Is RemoteApp and Desktop Connections? • Provides a personalized view of RemoteApp programs, session-based desktops, and virtual desktops The benefits of RemoteApp and Desktop Connections are: • RemoteApp programs run from the Start menu on the client • Includes published Remote Desktops and Virtual Desktops • Changes are automatically reflected on the user’s Start menu • Programs are easily accessed through Windows search • Does not require domain membership • Built on standard technologies • You can create a RemoteApp and Desktop Connections configuration file (.wcx) and distribute it to users
Accessing RemoteApp Programs from an External Network Network Policy Server/Domain Controller Terminal Server or Remote PC • RD GATEWAY Enables Terminal Services-based (RDP) connections without need for the broader capabilities of VPN • Requires Remote Desktop Connection 6.1 • Requires Microsoft Network Policy Server • Needs to be domain joined Validate User Access and Client Health 2 DATACENTER RDP over RCP/HTTPS AD/NP 3 Internal Firewall RCP/HTTPSRemoved External Firewall 1 Home RDP passed to Terminal Server Terminal Services Gateway MobileBusiness Internet 4 DMZ Branch Office
RDS Gateway In Action • RDP hosts can now be put behind firewall • HTTP/S used to traverse firewall • AD/NPS/NAP checked before connection allowed • New Remote Desktop Connectionclient required AD/NPS/NAP AD/IAS/NAP checked TS Gateway Vista RDC (TS) client RDP over HTTP/S established to TSG RDP 3389 to host Terminal Servers or XP/Vista User initiates HTTP/S connection to TS Gateway User browses to TS Web Access TS Web Access DMZ Internal Network Internet
