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.

It 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.
