Murano enables application developers and cloud administrators to publish various cloud-ready applications in a browsable catalog. Cloud users -- including inexperienced ones -- can then use the catalog to compose reliable application environments with the push of a button. Murano uses OpenStack Heat to orchestrate infrastructure resources for the application.
