The simplest option to address this requirement is to assign the Contributor role in the subscription to the Azure VM hosting the CycleCloud application.

+To manage resources in your Azure subscription, Azure CycleCloud requires a certain level of permissions. The simplest option to address this requirement is to assign the Contributor role and the Storage Blob Data Contributor role in the subscription to the system-assigned identity of that Azure VM hosting the CycleCloud application.
