Windows Remote Desktop Services
With Remote Desktop
Services (RDS), one of the core virtualization technologies available in Windows
Server 2008 R2, Microsoft is progressing in its vision to provide the best
virtualization platform for accelerating and extending desktop and application
deployments from the data center to any device. In addition to the traditional
session virtualization scenario (formerly known as “Terminal Services”), Remote
Desktop Services is expanding its role to provide an extensible platform for a
Virtual Desktop Infrastructure (VDI).
Remote Desktop Services
allows a user to access applications, data and even an entire desktop running on
a remote computer over a network. The client access device can either be a full
rich Windows personal computer, or a thin client (such as Windows CE device).
Remote Desktop Services works by allowing individual applications or an entire
desktop to run on a server, rather than on the user’s workstation. Remote
Desktop Services simply sends screen images to the users, and the user’s machine
in turn sends keystrokes and mouse movements back to the server. By doing this,
Remote Desktop Services allows clients to run applications or desktop
environments that they might otherwise not have the hardware or bandwidth to
support. On the server, applications and desktop environments can either run as
shared sessions, or in the context of a virtual machine environment (aka virtual
desktop infrastructure or VDI).
Device CAL
A Device CAL permits
one device (used by any user) to access or use the server software. Device CALs
are likely to be more cost-effective than User CALs if there are multiple users
per device (for example, a call center or an airport kiosk).
