Cloud IoT Core

A fully managed service to easily and securely connect, manage, and ingest data from globally dispersed devices.


Secure device connection and management

Cloud IoT Core is a fully managed service that allows you to easily and securely connect, manage, and ingest data from millions of globally dispersed devices. Cloud IoT Core, in combination with other services on Cloud IoT platform, provides a complete solution for collecting, processing, analyzing, and visualizing IoT data in real time to support improved operational efficiency.

Secure device connection and management

Make informed decisions at global scale

Cloud IoT Core, using Cloud Pub/Sub underneath, can aggregate dispersed device data into a single global system that integrates seamlessly with Google Cloud data analytics services. Use your IoT data stream for advanced analytics, visualizations, machine learning, and more to help improve operational efficiency, anticipate problems, and build rich models that better describe and optimize your business.

Securely connect your existing device network

Securely connect a few or millions of your globally dispersed devices through protocol endpoints that use automatic load balancing and horizontal scaling to ensure smooth data ingestion under any condition. Cloud IoT Core supports the standard MQTT and HTTP protocols, so you can use your existing devices with minimal firmware changes. Cloud IoT Core runs on Google’s serverless infrastructure, which scales automatically in response to real-time changes and adheres to stringent industry-standard security protocols that protect your business data.

Establish two-way communication with your devices

Bring device data into your everyday business through a secure, intelligent, and responsive IoT data pipeline created by Cloud IoT Core. Easily push your own device updates with Cloud IoT Core.

Get straight to work

Centrally manage your entire IoT data network from a single pane of glass. Cloud IoT Core works out of the box with devices from leading hardware manufacturers. You can easily reduce capital expenditures on your IoT projects and maintenance costs with a pay-as-you-go service.

Zero touch device provisioning to Cloud IoT Core

Cloud IoT provisioning service (early access) is an add-on service for Cloud IoT Core that simplifies the device provisioning and on-boarding experience for Cloud IoT customers and OEMs. It performs secure, hassle-free device provisioning by leveraging tamper-resistant hardware-based security, otherwise referred to as a crypto chip or Secure Element (SE) from OEM partners, enabling customers to provision millions of devices to the right Cloud IoT Core without human intervention.

Cloud IoT Core has two main components: a device manager and a protocol bridge.

Device manager

The device manager allows individual devices to be configured and managed securely in a coarse-grained way; management can be done through a console or programmatically. The device manager establishes the identity of a device, and provides the mechanism for authenticating a device when connecting. It also maintains a logical configuration of each device and can be used to remotely control the device from the cloud.

Protocol bridge

The protocol bridge provides connection endpoints for protocols with automatic load balancing for all device connections. The protocol bridge has native support for secure connection over industry standard protocols such as MQTT and HTTP. The protocol bridge publishes all device telemetry to Cloud Pub/Sub, which can then be consumed by downstream analytic systems.

End-to-end security
Enable end-to-end security using asymmetric key authentication over TLS 1.2; CA signed certificates can be used to verify device ownership. Devices supporting the Cloud IoT Core security requirements can deliver full-stack security.
Single global system
Connect all devices and gateways to Google Cloud over standard protocols, such as MQTT and HTTP, through the protocol endpoints and manage all your devices as a single global system. The service uses Cloud Pub/Sub underneath, which retains data for seven days.
Out-of-box data insights
Use downstream analytic systems by integrating with Google Big Data Analytics and ML services such as Dataflow, BigQuery, Bigtable, ML, Data Studio, or partner BI tools.
Fully managed and scalable
The service is serverless and doesn’t require any upfront software installation. It scales instantly without limits using horizontal scaling of Google Cloud Platform.
Role-level access control
Apply IAM roles to device registries to control user access to devices and data.
Device deployment at scale
Use REST APIs to automatically manage the registration, deployment, and operation of devices at scale. Also, use the APIs to retrieve and update device properties and state even when the devices are not connected.

“ Our devices are heavily used and constantly send us a huge volume of data. By connecting these devices to Cloud IoT Core, we have a secure and reliable way to not only ingest that data but then also use it to gain valuable insights. We know exactly how our systems are performing and can push updates to devices to ensure we deliver the best products and services as cost effectively as possible. ”

— John Heard Group CTO, Smart Parking Limited

“ Thanks to Google Cloud IoT, we could connect a large fleet of smart meters to the Cloud, and build a smart energy platform that provides a realtime view of power utilization and forecasts demand for power utility providers. ”

— Edwin Poot Founder, President & Chief Visionary Officer , Energyworx
