Mirantis first publicly released the FUEL library as an open-source effort in March of 2013. Now the FUEL effort has been formally approved by the OpenStack Foundation to be included under what is known as the ‘Big Tent’ model.
As part of the OpenStack Liberty release which debuted in October, OpenStack has moved from being a more limited set of integrated projects, to taking a broader view of projects that can be included – the so called Big Tent. Under the Big Tent model, many more projects than ever before are now considered to be official OpenStack efforts – and FUEL is now being added to that list.
