OpenStack is a cloud computing system software (sometimes referred to as cloud computing OS), that delivers Infrastructure as a Service (IaaS). Released under the Apache license, OpenStack is free open source software. The OpenStack Foundation was established in September 2012 as a non-profit corporate entity that manages the OpenStack project. It promotes OpenStack and its developer community.
