16. Microsoft and Community Tour 2011 – Infrastrutture in evoluzione Benefits of Virtual Desktop Infrastructure VDI is a centralized desktop delivery architecture, which allows you to centralize the storage, execution, and management of Windows desktops Benefits of VDI: Provides access to data and applications from any device Improves data security and compliance Simplifies management and deployment of applications Improves business continuity Integrates management of physical, virtual, and session- based desktops Centralizes data storage and backup Key deployment scenarios of VDI are persistent virtual machines and pooled virtual machines

17. Microsoft and Community Tour 2011 – Infrastrutture in evoluzione Desktop Virtualization Solutions Local Desktop Virtualization Provide virtualization at the local physical desktop Requires rich client operating system Uses local resources Offline solution Centralized Desktop Virtualization Provide virtualization from the data center Data is centrally stored and protected Update challenges Multiple operating system support available to meet needs Session Virtualization Provide virtualization from the data center Easier to configure and manage Remote desktop or remote application Single (shared) operating system instance

18. Microsoft and Community Tour 2011 – Infrastrutture in evoluzione VDI Virtual Desktop Models Personal Virtual Desktop One-to-one mapping between a user and a virtual machine Model requires the creation of a virtual desktop for each user Users can perform specialized tasks that require administrator access to their desktop Users can access their personalized desktop from any computer while retaining the last saved state (persistent configuration) Application streaming and application hosting support with App-V and RemoteApp Best for Knowledge Workers (software developers, testers, and so on)

19. Microsoft and Community Tour 2011 – Infrastrutture in evoluzione VDI Virtual Desktop Models Virtual Desktop Pool One-to-many mapping between a virtual machine and users Model requires a master VHD image that is duplicated or difference-based as needed to support user workload Users can perform standardized routine tasks and have access to common applications (such as Microsoft Office) Configuration state rolls back at logoff to provide a clean desktop for the next users session, but previous users state can be saved offline Application streaming and application hosting support with App-V and RemoteApp Analysis suggested to determine if session-based desktop is more efficient Best for Task or Office Workers (CRM, ERP, and similar users)

20. Microsoft and Community Tour 2011 – Infrastrutture in evoluzione Virtual Desktop Pool Considerations Identical Virtual Machine Configuration Operating system Applications Management VHD duplication and storage Single image update Windows Client Operating Systems Does not support Windows Server operating systems Does not support 3 rd party operating systems Single Pool Membership Virtual machines are restricted to membership in a single virtual desktop pool User Data Non-Persistent Data saved by user in a VM may not be accessible after log off Users may be connected to different virtual machine at next log on

21. Microsoft and Community Tour 2011 – Infrastrutture in evoluzione How Virtual Desktop Infrastructure Works A user can connect to a virtual machined based on the VDI configured for: Personal virtual desktops 1.A user initiates the connection to the personal virtual desktop 2.The user sends the request to the RD Session Host server running in redirection mode 3.The RD Session Host server forwards the request to the RD Connection Broker server 4.The RD Connection Broker server queries AD DS and retrieves the name of the virtual machine that is assigned to the requesting user account 5.The RD Connection Broker server sends a request to the RD Virtualization Host server to start the virtual machine 6.The RD Virtualization Host server returns the IP address of the FQDN to the RD Connection Broker server 7.The RD Session Host server redirects the request to the client computer that initiated the connection 8.The client computer connects to the personal virtual desktop Pooled virtual desktops 1. A user initiates the connection to the virtual desktop pool 2. The user sends the request to the RD Session Host server running in redirection mode 3. The RD Session Host server redirects the request to the RD Connection Broker server 4. The RD Connection Broker server verifies whether any existing session exists for the requesting user account 5. The RD Session Host server redirects the request to the client computer that initiated the connection 6. The client computer connects to the virtual desktop pool A user can connect to a virtual machined based on the VDI configured for: Personal virtual desktops Pooled virtual desktops

22. Microsoft and Community Tour 2011 – Infrastrutture in evoluzione Virtual Machines for Virtual Desktop RD Virtualization Host can assign each user a unique virtual machine, a personal virtual desktop, or can redirect users to a shared virtual machine pool, where a virtual machine is dynamically assigned After installing a virtual machine, you must configure the following to work with RDS: 1.Join the virtual machine to a domain 2.Enable Remote Desktop 3.Add user accounts to the local Remote Desktop Users security group 4.Allow RPC 5.Create a firewall exception to allow Remote Services Management 6.Add permissions to RDP
