I'm a bit uncomfortable as well. Part of our role at the Technical Committee is to make sure additions do not overlap in scope and make sense as a whole. Murano seems to cover two functions. The first one is publishing, cataloging and discovering software stacks. The second one is to deploy those software stacks and potentially manage their lifecycle. In the OpenStack "integrated" release we already have Glance as a publication/catalog/discovery component and Heat as the workload orchestration end. Georgy clearly identified those two facets, since the incubation request lists those two programs as potential homes for Murano. The problem is, Orchestration doesn't care about the Catalog part of Murano, and Glance doesn't care about the Orchestration part of Murano. Murano spans the scope of two established programs. It's not different enough to really warrant its own program, and it's too monolithic to fit in our current landscape. I see two ways out: Murano can continue to live as a separate application that lives on top of OpenStack and consumes various OpenStack components. Or its functionality can be split and subsumed by Glance and Heat, with Murano developers pushing it there. There seems to be interest in both those programs to add features that Murano covers. The question is, could we replicate Murano's featureset completely in those existing components ? Or is there anything Murano-unique that wouldn't fit in existing projects ? -- Thierry Carrez (ttx) _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
