Desktop-as-a-service (DaaS) is a form of virtual desktop infrastructure (VDI) in which the VDI is outsourced and handled by a third party. Also called hosted desktop services, desktop-as-a-service is frequently delivered as a cloud service along with the apps needed for use on the virtual desktop.
A Desktop-as-a-service provider typically handles storing, securing and backing up a user’s data, as well as upgrades for the DaaS service and supported applications. Some of the more well-known desktop-as-a-service providers include Amazon, Desktone (a VMware company) and Citrix.
