Eucalyptus: Identity and Access management!

“Elastic Utility Computing Architecture for Linking Your Program to Useful System”- shortly known as EUCALYPTUS is an open source private cloud software which is typically for building up the hybrid cloud resources for computing,networking and storage purpose. These private and hybrid cloud resources are highly compatible with Amazon web service (AWS) APIs.

OpenNebula: Users and group management!

opennebula

OpenNebula is most popularly used project by organizations as an open and flexible cloud virtualization program on their VMware-based data center that enables highly scalable hosting environments. OpenNebula classifies users into 4 categories: administrators(users belong to admin group), regular users (who can access most of the OpenNebula functionalities), public users(may access only public interfaces) and service users(having OpenNebula service account). the access of any resource highly depends on the category where a user falls in. User can share resources by granting access permission to other users in their group or to any other user in the system.
