OpenNebula is an open-source cloud computing toolkit for managing heterogeneous distributed data center infrastructures. The OpenNebula toolkit manages a data center's virtual infrastructure to build private, public and hybrid IaaS (Infrastructure as a Service) clouds. OpenNebula orchestrates storage, network, virtualization, monitoring, and security^[1] technologies to deploy multi-tier services (e.g. compute clusters^[2][3]) as virtual machines on distributed infrastructures, combining both data center resources and remote cloud resources, according to allocation policies. According to the European Commission's report about the future of cloud computing from a group of experts "... only few cloud dedicated research projects in the widest sense have been initiated – most prominent amongst them probably OpenNebula ...".^[4]

The toolkit includes features for integration, management, scalability, security and accounting. It also emphasizes standardization, interoperability and portability, providing cloud users and administrators with a choice of several cloud interfaces (EC2 Query, OGF OCCI and vCloud) and hypervisors (Xen, KVM and VMware), and a flexible architecture that can accommodate multiple hardware and software combinations in a data center.^[5]

OpenNebula was a mentoring organization in Google Summer of Code 2010.^[6]

OpenNebula is sponsored by C12G.

Use

OpenNebula is used by a variety of organizations, including hosting providers, telecom operators, IT services providers, supercomputing centers, research labs, and international research projects ^[7].
