The SMS service is dedicated to Cloud setup which can be integrated independent of work load manager (like condor, novello, other orchestrators etc). Though there are number of cloud security solutions that allow the users to use the allocated VM's or resources by the authorized owner like AAA, we are still facing of intrusion in the pubic clouds © 2012 Springer-Verlag.
