We use some nonessential cloud services to fill in a few gaps where I am at, mainly an email gateway and VPS. So in actuality I agree with some of the other comment.

But what I've found, in minimizing our dependencies on the cloud, is that for a small increase in implementation time (which isnt so bad because, again, people actually know what they're doing after some training) we have almost zero problems that we can't immediately go back and fix ourselves. And my shit gets done on time, and under budget.

edit: Also, resiliency is a legitimate business concern/objective. Sucks that you can't blame any problems on cloud providers tho :)
