Azure Data Box Gateway enables you to seamlessly send data from your on-premises applications to Azure.
It is a device based on a virtual machine provisioned in your virtualized environment or hypervisor. The virtual device resides in your premises and you write data to it using the NFS and SMB protocols. The device then transfers your data to Azure block blob, page blob, or Azure Files.
You can use the Azure portal to configure, manage, and monitor your Data Box Gateway devices.
