DaaS- provides the desktop environment either within a browser or as a terminal server.
Advantage
The technology allows businesses to host desktops from a central server room or data center. Like server virtualization, with which many SMBs are familiar, multiple PC operating systems are concentrated onto a few servers as virtual machines, which end-users access over the network. Each virtual PC is the exact working environment they would find if the operating system were running on physical hardware on the user’s desks.
Disadvantage
Desktop Virtualization is Cap-ex intensive. One needs to buy the Desktop Virtualization Software/Licenses, Servers, Centralized Storage infrastructure, Upgrade Network infrastructure to support more bandwidth, etc in addition to buying computers/ thin-clients for each user.
