 To accomplish seamless authentication with Azure and authorization to various Azure resources, the agent is registered with the following Azure services:
 
 - Azure Storage Mover (Microsoft.StorageMover)
-- Azure ARC (Microsoft.HybridCompute)
+- Azure Arc (Microsoft.HybridCompute)
 
 ### Azure Storage Mover service
 
 Registration to the Azure Storage mover service is visible and manageable through the storage mover resource you've deployed in your Azure subscription. A registered agent is an Azure Resource Manager (ARM) resource. You can only create this resource through the registration process. You can query details about the resource from any Azure Resource Manager client. Clients include the Azure portal, Az PowerShell module PowerShell and Az PowerShell module CLI.
 
 You can reference this Azure Resource Manager (ARM) resource when you want to assign migration jobs to the specific agent VM it symbolizes.

 Azure Storage Mover uses a system-assigned managed identity. A managed identity is a service principal of a special type that can only be used with Azure resources. When the managed identity is deleted, the corresponding service principal is also automatically removed.
 
 The process of deletion is automatically initiated when you unregister the agent. However, there are other ways to remove this identity. Doing so incapacitates the registered agent and require the agent to be unregistered. Only the registration process can get an agent to obtain and maintain its Azure identity properly.
 
 > [!NOTE]
-> During public preview, there is a side effect of the registration with the Azure ARC service. A separate resource of the type *Server-Azure Arc* is also deployed in the same resource group as your storage mover resource. You won't be able to manage the agent through this resource.

  It may appear that you're able to manage aspects of the storage mover agent through the *Server-Azure Arc* resource, but in most cases you can't. It's best to exclusively manage the agent through the *Registered agents* pane in your storage move resource or through the local administrative shell.

 These assignments are made in the admin's sign-in context in the Azure portal. Therefore, the admin must be a member of the role-based access control (RBAC) control plane role "Owner" for the target container. This assignment is made just-in-time when you start a migration job. It is at this point that you've selected an agent to execute a migration job. As part of this start action, the agent is given permissions to the data plane of the target container. The agent isn't authorized to perform any management plane actions, such as deleting the target container or configuring any features on it.

-> Access is granted to a specific agent just-in-time for running a migration job. However, the agent's authorization to access the target is not automatically removed. You must either manually remove the agent's managed identity from a specific target or unregister the agent to destroy the service principal. This action removes all target storage authorization as well as the ability of the agent to communicate with the Storage Mover and Azure ARC services.
