 **Level of risk exposed if this best practice is not established:** Low 

 **Benefits of establishing this best practice:** 
+  Visibility into cost drivers 
+  Identification of legacy resources for decommissioning 
+  Support for budget forecasting 

## Implementation guidance
<a name="implementation-guidance-59"></a>
+  Identified data transfer changes in cost data, such as by filtering Cost and Usage data by line\_item\_usage\_type for DataTransfer-Out-Bytes. 
+  Use cost dashboards to review usage patterns. For example, you can achieve this by using Amazon Athena and Amazon Quick Suite. 
+  Share findings in regular, weekly or monthly and FinOps reviews.
