The uncertain future of cloud computing and the plethora of frowny CIO faces of a couple years ago are rapidly giving way to the acceptance -- if not embracing -- of infrastructure as a service (IaaS), at least among IT leaders. The good news is that this shift is without the typical knee-jerk and shallow skepticism or naive Panglossian enthusiasm for the next new thing. This mental shift is tempered, real, and comes with more "buy" questions than "hold" or "sell" ones.
