A comparison and security analysis of the cloud computing software platforms

The first part of this paper describes most promising open-source cloud computing software platforms - Eucalyptus, OpenNebula and OpenQRM. With these platforms, it is possible to manage Infrastructure-as-a-Service operations. Non-commercial projects are analyzed, because they represent inexpensive but significant alternative to private and commercial software. The second part of the paper presents a suggestion of a new better security solution for cloud platform.
