AWS IoT Core is a managed cloud service from Amazon Web Services (AWS) that allows connected devices to securely interact with cloud applications and other devices. It is a platform that enables you to easily and securely connect devices to the cloud and to other devices, and build applications that interact with those devices.
For example, you could use AWS IoT Core to build a connected home security system that sends alerts to your smartphone when motion is detected. You could also use it to build a connected irrigation system that automatically adjusts the water usage based on the current weather conditions.
