<a name="aossus04-bp01"></a>

 Reduce costs, improve resource utilization, and enhance data protection by consolidating development and test workloads into fewer OpenSearch Service domains with implemented security features. 

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

 **Desired outcome:** You consolidate development and test workloads into fewer OpenSearch Service domains, with security features implemented to protect data. 

 **Benefits of establishing this best practice:** 
+  Reduced costs and increased cost efficiency 
+  Improved resource utilization and reduced waste 
+  Enhanced ability to manage and optimize resources 
+  Improved data protection and compliance due to security features 

## Implementation guidance
<a name="implementation-guidance-63"></a>

 Combining multiple workloads into a smaller number of OpenSearch Service domains not only minimizes compute and storage waste but also contributes to a reduction in carbon emissions. 

 Additionally, you can use fine-grained access control to implement tight security controls over your data.
