+### Using Virtual Endpoints for Consistent Hostname During Point-in-Time Recovery (PITR) or Snapshot Restore
 
-Learn how to [create virtual endpoints](how-to-read-replicas-portal.md#create-virtual-endpoints).
+This section explains how to use Virtual Endpoints in Azure Database for PostgreSQL - Flexible Server to maintain a consistent hostname during Point-in-Time Recovery (PITR) or Snapshot Restore, ensuring application connection strings remain unchanged.
+
+### Steps:
+1. Add Virtual Endpoint to Primary Server:
+    - Browse to your primary server instance in the Azure Portal.
+    - Navigate to “Replication” Tab, and under "Virtual Endpoints," click "Add Virtual Endpoint."
+    - Configure the virtual endpoint with a consistent hostname (e.g., `mydb-virtual-endpoint.postgres.database.azure.com`).
+    - Save the configuration.
+    - Update your application to use this virtual endpoint in the connection string.
+
+2. Perform Point-in-Time-Restore (PITR) or Snapshot Restore:
+    - Initiate Recovery:
+        - Go to the "Backups" section of your primary server.
+        - Choose the appropriate restore option (PITR or snapshot) and specify the desired point in time.
+    - Update Virtual Endpoint:
+        - Once the new instance is created, navigate back to the primary server settings.
+        - Remove the virtual endpoint from the original primary server.
+        - Add the same virtual endpoint to the newly created server.
+
+3. Validation:
+    - Ensure that your application connects using the virtual endpoint and verify the database operations post-recovery.
