IoT Hub

Definition & Role: An IoT hub is a cloud-based or on-premises platform that acts as a central message broker, managing bi-directional communication between IoT devices and applications.

Device Management: Supports registration, authentication, monitoring, configuration, and lifecycle management of connected IoT devices.

Protocol Support: Handles multiple communication protocols like MQTT, HTTPS, AMQP, and WebSockets, enabling interoperability among diverse devices.

Data Processing & Routing: Collects, filters, and routes telemetry data from devices to analytics platforms, databases, or applications for visualization and decision-making.

Security: Provides secure device-to-cloud communication through encryption, authentication, and access control, ensuring data integrity and privacy.

Applications: Used in smart homes, industrial IoT, connected vehicles, energy management, healthcare, and smart city projects to centralize device control and data analytics.
