IoT Core is a basic service to manage devices and to receive data from an edge device. To enable IoT Core, we need to open the web console and click on IoT Core as shown in the following screenshot:

In the next sections, we are going to activate the policy to connect an external device through MQTT/MQTTS, create certificates, and register a new device (which is called a thing by AWS). AWS IoT uses X.509 certificates to enforce MQTT security.
After registration, we can implement our device on a local PC.
