Remote access for professionals is a preeminent concern for many sectors of industry. Far more business is conducted on the road, and this need is making itself felt. The old standard for securely connecting to HQ becomes obsolete as operations become too unwieldy and complex to be conducted over limited bandwidth.
A virtual private network (VPN) allows a secure connection via unsecured public networks. A common business scenario is an employee using a VPN to access the company network from the road or at home. A core advantage to a VPN is the low resource demands. The server only has to maintain its end of the connection and serve the requested data. Any resource-intensive processing occurs on the machine that established the connection.
A virtual desktop, on the other hand, is an individual user interface stored on a remote server. This desktop virtualization separates the software from the physical machine. In this scenario, the local machine is only responsible for maintaining its end of the connection, sending input and displaying the results on screen. Everything else, including the resource-intensive processing, occurs on the remote server.
Compared to virtual private networking, there are a number of key benefits to a modern virtual desktop architecture, such as the one provided via a Dell virtual desktop system. This strategy is more consistent and reliable. It is more cost-effective and resource-efficient. It is faster and safer. It provides centralized administration, fewer compatibility issues and improved data integrity. It is also less demanding on clients and thus less complex.
In many business scenarios, consistency is a crucial factor because it translates to savings. Yet consistency is near impossible to achieve using traditional VPNs because each client connects to the system with a different configuration. With virtual desktops, the user’s configuration is irrelevant to performance, and this equates to savings because the system is more compatible and does not have to account for so many variables.
Customer service, in particular, greatly benefits from the use of virtual desktops, both in terms of performance and cost. Using the Dell virtual desktop, for instance, companies do not even require a centralized customer service representative (CSR) solution. Instead, the server can distribute the virtual desktops, which has video communication and the appropriate software client automatically, to CSRs, who can even be working from home.
The other most important issues are security and data integrity. With a VPN, there is diminished data integrity because the system relies on the client to send the updated data. With a virtual desktop, the updated data is automatically on the server. In terms of security, the virtual desktop is more secure because it is far more difficult to compromise the system when the most sensitive elements exist only on the server.
