To clarify, most of CDO (Consumer Devices Other) does run on AWS in the sense that NAWS is the target state, MAWS is legacy and actively (slowly) being migrated off of. CDO (including Alexa) has been using DynamoDB/Lambda/Kinesis/SQS etc forever, its just the compute and kind-of network layers that are still MAWS. Even then, a large part of CDO has moved from Apollo to ECS/FarGate/whatever unholy Hex or DataPath thing they're pushing these days
