You can use Kerberos in the cloud. It is not worse of better than certs.
If you can read memory of a machine you can (potentially) read its keys.
But this is the general risk that you take going into the cloud 
regardless whether you use PKI or Kerberos.

In general you do not want to store long term keys in the images but 
rather add them on the fly when the system is instantiated.
The ipa-client-install with OTP registration code provides this capability.

It seems that you are trying to overcomplicate things with no obvious 
reason.
If you need help with picking a better approach lest us know what 
exactly you are trying to accomplish.
