// AWS IoT provides secure, bi-directional communication between Internet-connected
// things (such as sensors, actuators, embedded devices, or smart appliances)
// and the AWS cloud. You can discover your custom IoT-Data endpoint to communicate
// with, configure rules for data processing and integration with other services,
// organize resources associated with each thing (Thing Registry), configure
// logging, and create and manage policies and credentials to authenticate things.
//
// For more information about how AWS IoT works, see the Developer Guide (http://docs.aws.amazon.com/iot/latest/developerguide/aws-iot-how-it-works.html).
// The service client's operations are safe to be used concurrently.
// It is not safe to mutate any of the client's properties though.
