Google Cloud's fully managed service for securely connecting and managing IoT devices at scale. Note: Google Cloud deprecated this service in August 2023, recommending migration to partner solutions or third-party IoT platforms. Like a postal service that closed down, directing customers to alternative delivery services.
Before deprecation, companies used Cloud IoT Core to connect industrial sensors to Google Cloud for analytics. Existing users migrated to solutions like ClearBlade or other IoT platforms integrated with GCP.
Cloud IoT Core was Google Cloud’s managed device connectivity and management service (MQTT/HTTP ingestion, device identity, auth). It was deprecated in Aug 2023, so there is no direct current GCP replacement. Closest equivalents are AWS IoT Core and Azure IoT Hub. On OCI, there isn’t a single like-for-like IoT hub service; common patterns use OCI Streaming (Kafka-compatible) plus custom device gateways or partner IoT platforms.
