Virtual desktop infrastructure (VDI) and virtual private networks (VPNs) are two technologies that your employees can use to remotely, securely access corporate networks and resources. VDI technology creates a virtual desktop on a central server. Your users can remotely access this desktop from any physical machine over the internet. You can use VDI to quickly and efficiently set up many virtual desktops for remote workers. In contrast, a VPN creates a private network connection between remote users and the corporate network over the public internet. VPN connections over the internet are less expensive and offer higher bandwidth than dedicated wide area network (WAN) links or long-distance, remote-dial links.
