VDI offers great benfits as it enables IT to centrally manage desktop resources from the data center, any changes such as installing and upgrading applications or applying patches can be made without requiring access to users’ devices and can be completely automated. VDI also offers a more secure approach to desktop computing and provides more control and an easier and less costly way to meet compliance requirements critical in some verticals like financials and healthcare. Finally, with the proliferation of mobile devices, VDI offers an easy way for users to access their desktop from anywhere and at anytime.
With VDI technology, virtual desktops are running in the data center and can be accessed by employees from thin terminals or laptops and mobile devices connected to the campus network.
VDI is latency sensitive as every user interaction needs to do a round trip from the physical device connected to the campus to the virtual desktop running in a data center. In order for virtual desktops to be as responsive as traditional PCs, the network needs to be able to deliver low latency end to end between the campus and the data center.
Additionally, the latest generation of VDI solutions such as VMware view, enables users to “check-out” their virtual desktop when they leave the office and “check it back in” when they return. This may result in busty data transfers across the network from the data center to the campus.
