DefinitionVDI (Virtual Desktop Infrastructure) runs each user's desktop environment in a virtual machine on a server, and the user operates that screen remotely from a terminal.
ExplanationA virtual machine is a virtual computer built by software inside one physical server, and VDI assigns one to each user. The terminal sends input and receives only screen information, so VDI is used as a way to achieve a thin client, where the terminal holds neither processing nor data. OS updates and security measures can also be handled together on the server.
AnalogyIt is like keeping your own private study at a hotel front desk. Whichever branch you stay at, once you get the key you can enter the same study.
Memory hookIt stands for Virtual Desktop Infrastructure. The name shows that what is virtualized is not a server but the desktop, meaning the user's screen environment.
