The successor to the Grizzly release of the OpenStack open source cloud computing platform (and the precursor to the 2014 OpenStack Icehouse release), OpenStack Havana debuted in October 2013 as the eighth release of OpenStack.
Among OpenStack Havana's most prominent feature additions are new orchestration and monitoring capabilities to go along with a variety of enhancements to the existing compute ("Nova"), storage ("Swift" and "Cinder") and networking ("Neutron") components.
The new features in OpenStack Havana help OpenStack deliver more enterprise-grade capabilities, with the orchestration component, "Heat," enabling the deployment of complex multi-tier services, and the monitoring component, "Ceilometer," responsible for managing and monitoring low-level cloud system events.
