I am not a fan of the cloud for business stuff. How do you guarantee they are backing it up, its integrity is good, when they do a 'change' to something on their end that causes an issue for something that connects to it. If something in the 'cloud' goes down you are at 100% mercy of them to get it back up and running...

For small, low user, or non critical, non sensitive data that is fine... but Payroll, Finance, AP, AR, Customer sensitive data.... nope. The NSA has proved that data insnt secure not to mention you have no idea how secury the cloud provider is and if they are being hacked.
