I often answer questions like this by posing two other questions
1) what notional dollar value can you place on the loss of service and information inherent in this AWS (in this case) deployment?
2) what % of that loss would you spend to limit exposure to that risk?
There is a third question:
Does your contract with Amazon include any penalties on AWS for service or data loss, beyond "free credits" and does it explicitly deny you rights to sue?
