Along the lines of what you mentioned - worries about data security are still the biggest hurtle. I can certainly understand that, particularly with respect to mission critical applications/data. Another one that I think is valid and I hear pretty often is concern about vendor lock in. I think these are related to some degree; any time you have to put your reliance in a third party, it can be a little nerve-racking. One I hear less often, unless a well publicized outage like Netlix's AWS issues on Christmas Eve has been in the press, is reliability and other performance concerns. Most of these are still legitimate concerns in my book. Of course, business should have many of the same concerns even if they keep things in-house.
