Developing on AWS IoT

In this example, we will adapt our previous MQTT application to the AWS cloud.

Before starting the example, we need to have an AWS account and install the aws command-line tool. If you haven't done so yet, the AWS documentation provides excellent guidance:

   $ aws --version
   aws-cli/2.1.31 Python/3.8.8 Linux/5.4.0-65-generic exe/x86_64.ubuntu.20 prompt/off

2. Create a thing using...
