Desktop virtualization (VDI): is it too complex?

I am following VDI technologies and solutions right from the days people started to talk about it (around 2003) and even participated in VDI technologies development in my days in Qumrant. After 8 years, I am reviewing the current VDI solutions, and I have one very clear observation: It is far too complex. With the complexity comes also high operations costs (OPEX) and expensive setups are required (== high CAPEX). I think that something very wrong happened with VDI along the way. Just to be clear, I am not criticizing a specific solution. I think that the dominate VDI architecture is just wrong, regardless of the vendor. As I see it VDI solutions are built like that:

Take a server virtualization technology, use it to run many desktops on each physical host, add a decent remoting protocol, multimedia acceleration (optionally also WAN acceleration),  desktop to user broker, user (login) portal and/or other access control, several provisioning mechanisms, several update/patch mechanisms, several image cleanup mechanisms, application virtualization, profile virtualization, application streaming, user data redirection, antivirus accelerator, a management console to manage pools, another one to manage applications, storage solution for the storage storms and network solution for the network storms. If I didn’t miss something critical (and I am sure I did), you have a VDI solution. Oops! I totally forgot the OS, the system utilities, and the applications (but they are old news ;-))…

The above seems to be a good base for another Carlin style gig (see Modern man) but it can’t be a good basis for a solid enterprise level solution.

I have many thoughts on why is this so, and what is the solution for it, but this has to wait to another post.
