Cloud IoT Core
Definition
Google Cloud's fully managed service for securely connecting and managing IoT devices at scale, enabling efficient data collection and processing.
Use Cases
- Google Cloud: Connected device telemetry ingestion for reference architectures and demos — Google Cloud published sample solutions that used Cloud IoT Core for device authentication (JWT), MQTT/HTTP telemetry ingestion, and routing messages into Pub/Sub, then processing with Dataflow and storing in BigQuery for analytics and dashboards. (Provided a repeatable blueprint for securely onboarding devices and analyzing telemetry at scale; after deprecation, these patterns shifted to partner platforms or custom ingestion into Pub/Sub.)
- ClearBlade: Migration path for organizations previously using Cloud IoT Core on Google Cloud — ClearBlade offered an IoT platform that can run on Google Cloud and integrate with GCP services (for example, forwarding device data into Pub/Sub/BigQuery). Organizations could replace Cloud IoT Core’s device connectivity and management functions while keeping downstream analytics on GCP. (Enabled continuity for existing GCP-based IoT pipelines by replacing the device gateway layer and reducing the need to redesign analytics and storage components.)
Provider Equivalents
- AWS: AWS IoT Core
- Azure: Azure IoT Hub
- OCI: OCI Streaming
Frequently Asked Questions
- What's the difference between Cloud IoT Core and Pub/Sub?
- Cloud IoT Core (when it existed) handled device-specific needs like device identity, authentication, and MQTT/HTTP ingestion. Pub/Sub is a general-purpose messaging service for applications. A common pattern was: devices connect to Cloud IoT Core, then messages are forwarded to Pub/Sub for processing by other services.
- When should I use Cloud IoT Core?
- You shouldn’t start new projects on Cloud IoT Core because it was deprecated by Google Cloud in August 2023. For new IoT solutions on Google Cloud, use a partner IoT platform or build a custom ingestion layer (for example, devices to an MQTT broker or HTTPS endpoint) and then route data into Pub/Sub, BigQuery, or other GCP services.
- How much does Cloud IoT Core cost?
- Cloud IoT Core is no longer available for new usage, so current pricing isn’t applicable for new deployments. Historically, costs depended on factors like the number of connected devices, message volume, and data ingestion/egress, plus downstream costs for services such as Pub/Sub, Dataflow, BigQuery, and storage. For migrations, estimate costs based on the replacement platform (partner or self-managed) and the same downstream GCP services you continue to use.
