AWS IoT and Alexa

The Alexa Voice Service (AVS) Integration is a new feature of AWS IoT Core that enables device makers to make any connected device an Alexa Built-in device. AVS for AWS IoT reduces both the cost and complexity of producing Alexa Built-in devices by offloading compute and memory intensive tasks from physical devices to the cloud.
