Open Source Cloud-Native Distributed MQTT Broker Server

Distributed MQTT Broker Server

The distributed MQTT Broker server is a message broker based on the publish/subscribe model. It supports load balancing and data synchronization across multiple nodes to provide high availability and scalability for MQTT messaging services. Here is a detailed explanation of the distributed MQTT Broker server:

1. Definition and Functionality

  • Definition: The distributed MQTT Broker server is a cluster of servers running MQTT messaging server software. It is responsible for receiving network connections from clients, handling client subscription/unsubscription, and message publishing requests, while forwarding messages published by clients to other subscribers.

  • Functionality: The distributed MQTT Broker server fully supports the MQTT protocol and can handle a large number of client connections and message transmissions. Through a distributed architecture, it can achieve load balancing and data synchronization among multiple nodes, providing high availability and scalability.

2. Key Features

  • Distributed Architecture: The distributed MQTT Broker server supports cluster deployment, enabling load balancing and data synchronization across multiple nodes. This architecture allows the system to easily scale service capabilities to meet the increasing demand for client connections and message transmissions.

  • MQTT Protocol Support: The distributed MQTT Broker server fully supports MQTT protocol versions V3.1 and V3.1.1 (with some supporting version 5.0), ensuring compatibility with existing MQTT clients.

  • High Availability and Scalability: By adopting cluster deployment and consistency algorithms (such as Raft), the distributed MQTT Broker server ensures high availability and data consistency. It also supports scaling by adding new nodes without downtime.

  • Rich Functionality: In addition to basic messaging capabilities, the distributed MQTT Broker server also supports data persistence, rule engines, ACL (Access Control List), and other rich features. These capabilities enable the system to better meet the needs of various application scenarios.

3. Application Scenarios

  • IoT Device Communication: The distributed MQTT Broker server can be used to connect and manage a large number of IoT devices, achieving efficient data transmission and device control.

  • Mobile Application Message Push: It supports real-time message push for mobile applications, providing stable messaging services for mobile apps.

  • Message Queue Middleware: In complex system architectures, the distributed MQTT Broker server can serve as message queue middleware, enabling decoupling and asynchronous communication between systems.

4. Common Products

  • MMQ Broker: A distributed MQTT messaging server designed for IoT, machine-to-machine (M2M), and mobile applications. It fully supports MQTT protocol versions V3.1 and V3.1.1, featuring distributed architecture, data persistence, rule engines, ACL, and more. It also provides bridging capabilities with various databases and a plugin system to meet users’ customization needs.

  • EMQX: A highly scalable distributed MQTT Broker suitable for enterprise-level industrial IoT deployments. It supports multiple protocols, such as MQTT 5.0, MQTT-SN, and has high availability and horizontal scalability. EMQX can be deployed in the cloud or at the edge, widely used in industrial IoT fields such as automotive manufacturing and steel manufacturing.

In summary, the distributed MQTT Broker server is a powerful, highly available, and scalable messaging broker widely used in IoT and mobile applications. By selecting the appropriate distributed MQTT Broker server product, developers can build stable and efficient messaging systems.
