There's something about running your services on the same physical hardware as a bunch of other, potentially malicious, parties that just gives me the heebie-jeebies.

This is why cloud providers offer the option of dedicated provisioning where you can use the cloud APIs but ensure that your VMs run on hosts dedicated to your organization.

VMs have been used in the Real World for going on five decades now, in the form of VM (formerly CP) on IBM System/360 mainframes et seq. The threat model may have changed, but I don't even know if that's necessarily true.
