**CMSUS\_BP13.1: Use managed device farms for testing**

For more details, see [SUS06-BP04](https://docs.aws.amazon.com/wellarchitected/latest/sustainability-pillar/sus_sus_dev_a5.html) in the *Sustainability Pillar whitepaper*. 

**Prescriptive guidance:**
+  Establish cloud native testing practices to understand expected impact, and test with customers to understand the actual impact from using your services. Device farms are the second-best option. 
+  Use managed device farms to help you streamline the testing process for new features on a representative set of hardware. Managed device farms offer diverse device types including earlier, less popular hardware, and avoid customer sustainability impact from unnecessary device upgrades.
