This whitepaper focuses on best practices for designing MQTT topics in Amazon Web Services (AWS) Internet of Things (IoT). It covers how developing an optimal MQTT topic schema can improve the overall architecture of your IoT applications by providing greater visibility into cloud to device communication, providing more fine-grained security permissions, and enhancing integration options with other AWS IoT services, such as the AWS IoT Rules Engine, AWS IoT Device Shadow, AWS IoT Device Management, and AWS IoT Analytics.

This whitepaper is intended for technical architects, IoT cloud engineers, and embedded engineers. This paper assumes the reader has an understanding of fundamental MQTT concepts and terminology.
