A big advantage is that when an Internet connection is cut off, it doesn't affect a file in process, as it would with a standard VDI deployment. The user can keep working on the file on the client as usual, and when the connection is restored, the client and server automatically sync up both versions to result in the most recent version of the file.
not to roll your eyes at this statement: Virtual desktops for enterprises large

you undoubtedly have heard that one before-about every year since 1998, or
perhaps even earlier than that. But thanks to widespread broadband
availability, vastly improved networking hardware and software from competing
vendors, and the fact that many C-level executives frankly are up to here with
upward-spiraling licensing fees, VDIs (virtual desktop infrastructures) in
several forms are getting closer looks from more potential users than ever.
idea of deploying processor-less terminals connected to a central enterprise
computer system goes way back to the dawn of digital IT. The benefits of a
virtual desktop system have long been apparent: faster deployment and
disconnection of employee desktops as needed, lower licensing costs, less
complexity, automatic software updates and security patches, easier and more
efficient policy enforcement, and so on. All of those features are gold for
VDI often can require a non-trivial up-front investment in hardware, software
and training, market competition is helping bring pricing down. Also, the
inherent problems that shackled VDI for a long time-latency and security
issues-are being solved by improvements as each new-generation system becomes
deployments still have limitations involving the number of users and geographic
locations of clients. However, with market demand on the rise, it is a given that
there is more innovation to come that will solve those issues.
subsector of VDI that is earning the most attention at this time is client-side
VDI; it differs from server-based VDI in that each actual client, as well as the
server, holds a VDI agent-whether it be a hypervisor-like one or a simpler
connector to the server.
