Here is what I think VDI means – but I’d love to hear your opinion (maybe we will run a poll to get your thoughts about VDI).
VDI is an architecture or a computing model, running desktops on a virtualization infrastructure in the data center and virtually delivering them to end points anywhere. Minimal components of VDI are:
1. Virtualization infrastructure that can host virtual desktops in the data center
2. Windows desktops running in a virtual machine
3. Desktop delivery – including brokering and protocol to connect users to their virtual desktops from anywhere seamlessly
4. End point devices capable of receiving virtual desktops
5. Servers to run virtual desktops
I am sure different vendors will have their own offerings to extend the above list. For example – Citrix XenDesktop contains virtual desktop provisioning technologies for IT to be able to easily manage their virtual desktop image (SOE) without cloning and dealing with clone-sprawl.
I have seen that the understanding for VDI and desktop virtualization has grown significantly during 2007. Now, we are getting to a point where we need to standardize on terminology for more customers to be able to better understand the technology and associated benefits.
