AWS IoT Core is a managed cloud platform that lets connected devices easily and securely interact with cloud applications and other devices. It is a service that enables you to easily and securely connect and manage Internet-connected devices such as sensors, actuators, embedded micro-controllers, or smart appliances to the AWS cloud.
For example, you could use AWS IoT Core to connect a fleet of smart thermostats in different cities to an AWS Lambda function that adjusts the temperature of each thermostat based on the city’s weather forecast. You could also use AWS IoT Core to connect a fleet of smart meters to an Amazon Kinesis Data Firehose stream to ingest and process the data for analytics.
