In contrast to the control plane, which doesn't carry user data, internal data plane does transfer data stored in your databases. Similar to the control plane, endpoints and services within the internal data plane are managed and secured by Microsoft.

+- Traffic from the SQL managed instance to storage accounts where automated backups are kept.
+- Traffic to telemetry endpoints.
+-	Authentication and secret exchange with Microsoft Entra ID and Azure Key Vault.
+- Traffic to virtual machine image download endpoints and the Windows Update service.
+- Data transfer operations initiated and governed by the service, such as data backups, and some data replication between replicas.
+- Fabric mirroring traffic.
