Remote Desktop Services (RDS) was previously known as Terminal Services prior to Windows Server 2008 R2, which focused on session-based virtualization. Terminal Services was renamed to show the shift in focus from pure session-based virtualization to session-based and VDI scenarios.

Reviewing the Components of a Successful VDI Implementation

Figure 11-1 shows users whose devices are directly connected to a virtual machine. Although this is a basic form of VDI, it is completely impractical and likely wouldn’t work in the real world. For a successful VDI implementation, a number of components are needed:

  • Machine virtualization to host the virtual machines
  • Virtualization management to enable the creation of virtual machines, to stop/start them as needed, and to pass information back to the VDI components
  • Client platform to run inside the virtual machines, such as Windows 7 or Windows 8
  • Access protocol to communicate with the virtual desktop OS, which is Remote Desktop Protocol
  • Session Broker to decide which virtual desktop a user should be connected to and to remember which desktop a disconnected user was last using
  • Gateway capability for users connecting from outside of the corporate network, avoiding the need for virtual private network (VPN) connections
  • Licensing (Yes, you ...
