I think the problem is configuration. Every thing that has its own configuration is basically a new language you must be able to speak perfectly. Configuration languages are not statically typed so when you make an error it typically does not tell you you made a mistake, and where, and thy it is a mistake.

With Cloud stuff you have more configuration to do because it is about configuring virtual servers etc. Instead of carrying the PC in a box to your room you must "configure it" to make it available.
