Cloud based idiocy
It's like telling a secret. As soon as you put your valuable data in the cloud, on somebody else's servers, you have lost control of that data forever. It's not your data any more. You have no way of knowing, let alone controlling who has access to it or what they do with it. You can't take it back, you can't delete it. You can't even access it yourself unless you keep up the payments.
If your data is supposed to be confidential, then keep it confidential. Do not put it in the cloud. Keep it on your own servers. Employ competent and trustworthy people to manage it. It baffles me how many people don't understand this.
