 * **Azure Stack Edge resource** – a resource in the Azure portal that lets you manage an Azure Stack Edge device from a web interface that you can access from different geographical locations. Use the Azure Stack Edge resource to create and manage resources, view, and manage devices and alerts, and manage shares.

 ## Region availability
 
 Azure Stack Edge physical device, Azure resource, and target storage account to which you transfer data do not all have to be in the same region.
 
 - **Resource availability** - For a list of all the regions where the Azure Stack Edge resource is available, see [Azure products available by region](https://azure.microsoft.com/global-infrastructure/services/?products=databox&regions=all). Azure Stack Edge can also be deployed in the Azure Government Cloud. For more information, see [What is Azure Government?](https://docs.microsoft.com/azure/azure-government/documentation-government-welcome).
 
-- **Destination Storage accounts** - The storage accounts that store the data are available in all Azure regions. The regions where the storage accounts store Azure Stack Edge data should be located close to where the device is located for optimum performance. A storage account located far from the device results in long latencies and slower performance.

 ## Next steps
 
 - Review the [Azure Stack Edge system requirements](data-box-edge-system-requirements.md).
 - Understand the [Azure Stack Edge limits](data-box-edge-limits.md).
 - Deploy [Azure Azure Stack Edge](data-box-edge-deploy-prep.md) in Azure portal.
