Use RDS (Remote Desktop Services) hosts for providing published applications and session-based remote desktops to end users.

An RDS host can be a physical machine or a virtual machine. This example uses a virtual machine with the specifications listed in the following table. The ESXi host for this virtual machine can be part of a VMware HA cluster to guard against physical server failures.

Table 1. RDS Host Virtual Machine Example
Item Example
Operating system 64-bit Windows Server 2008 R2 or Windows Server 2012 R2
Virtual CPU 4
System disk capacity 40GB
Virtual SCSI adapter type LSI Logic SAS (the default for Windows Server 2008)
Virtual network adapter VMXNET 3
1 NIC 1 Gigabit
Maximum number of client connections total (including session-based remote desktop connections and remote application connections) 50
