Virtual desktop infrastructure (VDI) is a virtualization solution that uses virtual machines to provide and manage virtual desktops. VDI hosts desktop environments on a centralized server and deploys them to end-users on request. accessed over the network with an endpoint device (laptop, tablet, and so on).
With a VDI solution in place, organizations can realize a number of benefits. The desktop computing takes place on the host server, rather than at the endpoint device, so the hardware requirements for the endpoint are lower. This potentially makes the investment in an endpoint device lower, and it may be easier to support a diverse range of remote and mobile devices. As the hardware needs of the desktop software change, it may also be easier to reallocate CPU and memory from the server side than from the endpoint devices.
Security and configuration management are additional benefits of the VDI solution. Because all data lives in the data center, any loss of an endpoint device limits the exposure of the data that is not stored in the device. In environments with standardized desktop configurations that do not need to be customized for each user, a VDI instance offers strict controls to eliminate deviation from organizational standards.
