To Juju, a cloud (or backing cloud) is a resource which provides machines (instances), and possibly storage, in order for application units to be deployed upon them. This includes public clouds such as Amazon Web Services, Google Compute Engine, Microsoft Azure and Kubernetes as well as private OpenStack-based clouds. Juju can also make use of environments which are not clouds per se, but which Juju can nonetheless treat as a cloud. MAAS and LXD fit into this last category. Because of this, in Juju a cloud is sometimes also called a substrate.
