Learn in the textbookCloud Service Models (○aaS)
DefinitionDaaS (Desktop as a Service) is a model that runs a PC's desktop environment (デスクトップ環境), including the OS, applications and data, on a cloud server and delivers it over the network to the user's device.
ExplanationProcessing and data storage happen on the server, while the device shows the screen and sends keyboard and mouse input to the server. Because no data needs to stay on the device, losing it is less likely to leak information, and the same environment can be called up from another device.
AnalogyIt is like leaving your study in a distant building and, wherever you are, working at its desk through a window.
Memory hookD stands for Desktop. What arrives is not a single app but everything on top of the desk.
