<a name="sustainability"></a>

The sustainability pillar provides design principles, operational guidance, best practices, and improvement plans to meet sustainability targets for your AWS workloads. You can find additional guidance on implementation in the [Sustainability Pillar](https://docs.aws.amazon.com/wellarchitected/latest/sustainability-pillar/sustainability-pillar.html) of the AWS Well-Architected Framework.

## Design principles

 When designing advertising workloads, consider the following principles to optimize your workloads for sustainability objectives: 
+  Set sustainability goals internally and with advertising partners to meet business objectives. 
+  Implement low-latency workloads only for time-critical business requirements. 
+  Use serverless computing, containerisation, and cloud-native technologies to scale resources dynamically. 
+  Region selection is a complex factor for implementing advertising workloads. 
+  Back up and archive data only when challenging to recreate.  
+  Establish an iterative process to review sustainability objectives and ensure workload usage is not exceeding service level agreements (SLAs).
