I learnt this lesson the hard way. Solution: get a separate debit (not credit!) card for all cloud stuff. Make sure you only transfer enough money on to it each month to cover what you reasonably expect your bills to be (and that you can quickly top it up in hours if you legitimately need to).
Worst case, if AWS or Google decide to fuck you over, let the bill bounce. This way you've still got funds on hand to deal with the fall out and some leverage to negotiate a solution.
