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 (GCP) was a managed device connectivity and management layer (MQTT/HTTP ingestion, device identity, auth). AWS IoT Core and Azure IoT Hub are the closest equivalents and remain active. Oracle Cloud Infrastructure does not have a single, direct, first-party equivalent that matches Cloud IoT Core’s full managed IoT device gateway + registry pattern; OCI implementations typically use a combination of messaging/streaming plus partner IoT platforms.
