IoT Smart Home
This document provides an overview of IoT and the AWS IoT platform. It discusses key IoT concepts like MQTT and smart home devices. It then details various aspects of the AWS IoT architecture including AWS IoT Core services, security, and pricing. Device SDKs and protocols are covered, as well as how AWS IoT integrates with other AWS services like Lambda, S3, DynamoDB through the AWS IoT rules engine. Device shadowing and registry services are also summarized. Finally, AWS IoT is compared to the Azure IoT Suite in terms of features.
