Azure's managed cloud service for bi-directional communication between IoT applications and devices, with built-in device identity registry and security features. Like a sophisticated switchboard operator that manages millions of simultaneous device conversations securely.
A logistics company uses IoT Hub to track fleet vehicles in real-time, sending route updates to drivers while receiving location and diagnostics data from thousands of trucks.
Azure IoT Hub and AWS IoT Core are managed device connectivity platforms (device identity, secure bi-directional messaging, and routing to cloud services). Google Cloud previously offered Cloud IoT Core, but it was retired; common replacements use partner solutions or Pub/Sub-based architectures. OCI does not have a direct, first-party equivalent with the same breadth; implementations typically combine messaging (streaming/queue) plus device security/identity patterns.
