Anyone who has tried to to run graphics-intensive applications using an application-sharing protocol like RDP knows how miserably these technologies fail. But the PCoIP protocol and special hardware means that even heavy-duty workstations can operate remotely.

Powerful workstations for demanding graphics tasks are usually expensive and produce a lot of heat and fan noise. These devices also often process sensitive data that must not be lost or allowed to fall into the hands of competitors. Moreover, the same data might need to be accessed by multiple users at different locations, such as for a joint venture in which several companies are developing a product.

Thus, maximum data security, (through centralized data storage and the ability to assign restrictive permissions) as well as spatial and geographic independence (through the distributed use of central resources and workplace ergonomics) favor the use of remote, instead of static, workstations.

For these reasons, it makes sense to set up workstations at the data center, where they are under the control of the IT department and can be more easily integrated with the existing data center infrastructure (e.g., access control, centralized backup processes, UPS, air conditioning). Furthermore, this arrangement prevents physical access to the hardware, removing the ability of data thieves simply to clone or remove the hard disk with the project data.

The PCoIP (PC over IP) technology was developed by the Canadian company Teradici [1] specifically to display graphical output over IP networks (see the "Advantages of PCoIP" box). PCoIP transmits audio and USB signals, as well. Most administrators are probably already familiar with PCoIP from VMware's VDI solution, VMware Horizon View [2]; VMware licensed PCoIP from Teradici and integrated it into their own product.

Advantages of PCoIP

In contrast to the widespread terminal server protocols, PCoIP is much faster and achieves virtually lossless representation of graphically demanding
