Classic Server-Client Concept
This aging model involves installations on every PC. Under this concept, programs are installed directly on the client machine. The advantage is that each client PC has its own customized program installations. The downside is that changing workstations is not easily possible. Consider the administrative assistant's computer as an example: if it fails, a new computer is required that mirrors the exact program installations and system settings. In some cases, data is stored locally on these machines, which complicates the backup strategy.
Terminal Server Concept
This concept manages program installations centrally. The client PC simply receives a session that is displayed on its screen. The advantage is that changing workstations is easy; the session display can be projected onto any smartphone, iPad, or future computing system. Specialized software optimizers—such as WAN accelerators—allow terminal server screens to be transmitted efficiently even over low-bandwidth internet connections.
Virtual Desktop
Virtual Desktop ist die Symbiose aus beiden Varianten, sprich dem klassischen Server-Client- und Terminalserver-KonzeptVirtual Desktop represents a hybrid of the two approaches—the classic server-client model and the terminal server concept. The result is a highly customized desktop that incorporates the characteristics of a terminal server.
