B. Make data driven decisions to determine cloud architectural design D. Test systems at production scale "Drive architectures using data: In the cloud, you can collect data on how your architectural choices affect the behavior of your workload. This lets you make fact-based decisions on how to improve your workload. Your cloud infrastructure is code, so you can use that data to inform your architecture choices and improvements over time." "Test systems at production scale: In the cloud, you can create a production-scale test environment on demand, complete your testing, and then decommission the resources. Because you only pay for the test environment when it's running, you can simulate your live environment for a fraction of the cost of testing on premises." https://wa.aws.amazon.com/wat.design_principles.wa-dp.en.html
