Re: Cloud. Restictions? Sure anything, just sign here.
On the flip side, how paranoid do you need to be that you think your data is so valuable, that a multi billion dollar corporation is going to put their entire business at risk to steal it?
As soon as someone can demonstrate "aws stole our data" their business collapses as everyone goes back to on prem.
Maybe the odd individual would steal data, but it is all pretty well tracked and logged, so the individual can be punished. Just like an individual in your org could steal data. But I have worked for banks and governments and telcos and never seen anything anywhere near as good as the protection/logging/monitoring/etc. that AWS claim to have.
So yes, if you want a substandard solution that doesn't address the most likely risk, help yourself.
