Is homomorphic encryption ready to deliver confidential cloud computing to enterprises?

Cloud computing on a certified, compliant, properly-run cloud service like Microsoft Azure is likely to be far more secure than on-premise servers in your office or your data centre. Your data is encrypted at rest and in motion; cloud systems are probably patched more often and configured more securely than your servers; and admin access is locked down and only enabled for'just enough access, just in time' to run specific commands within specific time windows. Also, the admins will have gone through background checks and work in secure locations that require biometric credentials to access. Unlike nuclear weapons, cyberweapons can be proliferated more quickly and the threat from accidentally setting them off is even greater. There are still problems, though.
