What is Cluster Linking?

Cluster Linking is an advanced feature of EMQX that allows you to federate multiple EMQX clusters distributed across different geographical regions into a single, cohesive network. This technology creates a global, unified namespace for your IoT messaging infrastructure, enabling seamless communication between devices connected to different clusters. This is especially crucial for businesses that require uninterrupted IoT operations and a unified view of their global infrastructure.

Key aspects of Cluster Linking:

Global Connectivity: Connect EMQX clusters across multiple data centers, regions, or continents.
Unified Namespace: Maintain a single, consistent topic space across all linked clusters.
Intelligent Message Routing: Efficiently route messages between clusters based on actual subscriptions, minimizing unnecessary data transfer.
Scalability: Easily expand your IoT infrastructure to meet growing global demands.
Resilience: Implement robust disaster recovery and high availability strategies across regions.

By leveraging Cluster Linking, organizations can build truly global IoT solutions that offer seamless inter-region communication and data consistency, while maintaining the simplicity and efficiency of a single logical MQTT broker. This approach allows for the optimal placement of EMQX clusters near device populations, balancing global reach with regional performance.

Benefits

Global Distribution

Deploy EMQX clusters in multiple regions.
Ensure low-latency access for devices worldwide.
Maintain a unified view of your entire IoT ecosystem.

Seamless Communication

Enable cross-region device-to-device messaging.
Create a transparent, low-latency global network.
Cost saving by reducing unnecessary message routing across regions.

Disaster Recovery

Implement robust multi-region failover.
Ensure business continuity during regional outages.
Seamlessly transfer client connections between clusters.

How Cluster Linking Works

EMQX Cluster Linking creates a unified namespace across multiple clusters, allowing efficient message routing based on actual subscriptions and client distribution. This approach minimizes unnecessary message replication and ensures optimal performance.

Use Cases

Automotive Industrial IoT Healthcare

Automotive

In the automotive industry, connected vehicles rely on real-time data exchange between vehicles, traffic infrastructure, and cloud services across different regions. Cluster Linking ensures low-latency communication and high availability, allowing vehicles to seamlessly switch between regional clusters as they move across borders. This is crucial for applications such as live traffic updates, autonomous driving, and vehicle-to-everything (V2X) communication.

Industrial IoT

For manufacturing and industrial automation, Cluster Linking provides a robust solution for managing IoT devices across multiple facilities and regions. By connecting EMQX clusters in different locations, factories can synchronize production lines, monitor equipment health in real-time, and perform predictive maintenance. This global communication network enhances operational efficiency and reduces downtime by ensuring that critical data flows uninterrupted across all facilities.

Healthcare

Healthcare applications, such as remote patient monitoring and telemedicine, require secure and reliable data transmission across regions. Cluster Linking ensures that healthcare providers can access patient data in real-time, regardless of the patient's location. This is especially critical for monitoring patients with chronic conditions, where timely data can make a significant difference in patient outcomes.

Cluster Linking vs. MQTT Bridge

While both technologies enable connectivity between MQTT brokers, Cluster Linking offers several advantages:

	Cluster Linking	MQTT Bridge
Namespace	Unified namespace	Separate namespaces, prefixing needed
Message Routing	On-demand, efficient	Full topic replication
Message Looping	Automatically avoids loops	Requires bridge mode to avoid loops
Performance	Optimized for large-scale deployments	Varies
Integration	Native EMQX feature	Works with any MQTT broker
