VDI:
What VDI is?
• Centralizes the storage, execution, and management of Windows desktops
Key deployment scenarios of VDI are persistent virtual machines and pooled virtual machines
Key deployment scenarios of VDI are persistent virtual machines and pooled virtual machines
• 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
Pooled virtual desktops
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.
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 2012 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
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
RD Connection Broker enables user connections to connect to an appropriate endpoint
RD Connection Broker enables user connections to connect to an appropriate endpoint
Configuring Virtual Machines
Supported operating systems:
• Windows 7• Windows 8/8.1
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?
Benefits of application virtualization are:Centralized management
Scalable infrastructure
Accessible applications
Remote Desktop Server support
Reduced license compliance risks
Usage reporting
Application virtualization allows you to run applications on client computers as if they were installed locally
Application virtualization allows you to run applications on client computers as if they were installed locally
Access anywhereOver the web
Portable devices
Just in time deployment (Click-to-Run)Installer does not run
Instant gratification
Simple servicingUpdate once, deliver everywhere
Users automatically stay up to date
Run applications as a “service”
No changes to systemSafely run apps side-by-side
No OS decay over time
Lower migration costs
State separationStore App state separate from OS state
State categorized as user versus system
User state stored in profile, roams with profile
Run applications without conflicts
App packaged using Sequencer
Installation monitored to capture resources
App image placed on server for distribution
App streamed to client over network
SMB, HTTP(S)
App-V runs app in Virtual Environment (VE)
App virtualization layer handles resource requests
How Does It Work?
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
Use Microsoft Application Virtualization to stream applications on-demand
What Is App-V Desktop Client?
Application VirtualizationManagementServer
ApplicationVirtualizationDesktop Client
Network
• Requests applications to be streamed• Receives the application code• Sets up the runtime environment• Executes the code locally
In Microsoft Application Virtualization (App-V) 5.0 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.
App-V 5.0 Shared Cache for VDI environments
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

App-V Remote Desktop Client
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
What Are RemoteApp 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
• Can run along with local programs on the client computer
• Has its own resizable window and entry on the taskbar
• Can share a RD session with another RemoteApp program on the same terminal server
RemoteApp programs run remotely on RD Session Host server and can integrate with locally running programsRemoteApp programs run remotely on RD Session Host server and can integrate with locally running programs
What Is RemoteApp and Desktop Connections?
Provides a personalized view of RemoteApp programs, session-based desktops, and virtual desktopsProvides 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
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
