# FSISUS08: How do you optimize your resource usage?
<a name="fsisus08"></a>

 Review and optimize your resource usage by implementing either a pub/sub or pull mechanism instead of relying on a polling approach. 

## FSISUS08-BP01 Use event-driven architecture

 Implement either a pub/sub or pull mechanism instead of using a polling approach. 

### Prescriptive guidance
<a name="prescriptive-guidance-16"></a>
+  Implement event-driven architecture where possible to avoid idling of resources running and waiting for state changes. 
+  If event-driven architecture is not possible, modify the capacity of individual components to prevent idling downstream resources waiting for input. 
+  Avoid polling APIs or queues, instead have components and services subscribe to events or be notified of changes to reduce the idling of resources. 
+  Implement auto scaling and serverless architectures for generative AI workloads. 
+  Use managed generative AI services like Amazon Bedrock to optimize resource utilization. 
+  Apply model optimization techniques like quantization and pruning.
