The Best MQTT Broker for Google Cloud

Seamless integration with the Google Cloud for data ingestion at hyper-scale

HiveMQ is an MQTT-based messaging platform designed for the fast, efficient and reliable movement of data to and from connected IoT devices. It uses the MQTT protocol for an instant, bi-directional data exchange between your device and your enterprise systems.

HiveMQ’s Enterprise MQTT platform is based on Open Standards and deployed in hybrid and multi-cloud environments in multiple industries.

Google Cloud and HiveMQ: Scale and Flexibility

It’s easy to get started

HiveMQ runs natively in Google Cloud (including in GKE) and integrates seamlessly with services via its Google Pub/Sub extension.

Leverage the power of the Google Cloud Platform without relying on Google IoT Core.
Smooth transition — simply plug HiveMQ’s MQTT broker and the Google Pub/Sub extension into your IoT environment and continue business as usual.
Ingest data from 10s of millions of connected devices and feed it directly into existing data Google Cloud pipelines.
Manipulate MQTT device data in Google Cloud Platform analysis tools (e.g. BigQuery) to uncover crucial insights from their IoT devices in the field, all within their existing data pipeline.
Build reliable and scalable business-critical IoT applications
Fast routing and delivery help build responsive applications
Low cost of operation through efficient use of hardware, network, and cloud resources to integrate IoT data into existing enterprise systems.

Key Features — HiveMQ Google Pub/Sub Extension


HiveMQ’s Google Pub/Sub extension can be easily configured according to your requirements. Send Pub/Sub messages to MQTT topics via configurable adaptation of their content The extension is easily configurable using HiveMQ’s Customization SDK With the 4.12 release, this extension can now convert MQTT topics to Google Pub/Sub custom attributes. You can use these custom attributes for filtering or include metadata that is separate from the message itself.	Control the entire MQTT Pub/Sub pipeline with smart customization features. Allows for fully customizable Transformers, giving customers complete control of the MQTT⇔Pub/Sub process
