thing-data-viewer

This project contains an infrastructure stack in the /infra folder, written in TypeScript using CDK CDK project that will deploy the following:

• An IoT Core Rule
• A Lambda
• A Cloudwatch Custom Dashboard

As for the device sending information to that cloud infrastructure, you will find the code here

When your device sends a message with some data over MQTT to the cloud, what will happen is this:

• The AWS IoT MQTT engine will receive it, and will match it against the rules it have
• The rule will be triggered and it will call a lambda (serverlesss function)
• The lambda will put that data into custom Cloudwatch metrics. These metrics will then be monitored in a Cloudwatch dashboard.
