A cloud object model represents resources available in a cloud computing environment as hardware islands. A compute cluster is registered with a hardware island. The compute cluster is designated as being of a particular cluster type. An indication is received from a user to provision the compute cluster with storage. The object model is accessed to determine a cluster type of the cluster. The cluster is provisioned with storage of a type that corresponds to the cluster being of the particular type, where the storage provisioned includes one of replicated storage or non-replicated storage.
