EMQX Enterprise 5.1 introduces a revolutionary architecture powered by the Mria cluster architecture. Our new groundbreaking architecture enables EMQX to handle billions of concurrent IoT connections. In our latest version, a single cluster will scale up to 23 nodes, supporting over 100 million MQTT connections. This represents a tenfold increase in access capacity, marking a significant improvement from the previous 4.x version.
Our enhanced architecture brings robust horizontal scalability and also ensures higher reliability. The unique core-replicant node pattern allows you to add or remove nodes without disrupting operations. This ability to hot-swap nodes provides the flexibility to scale the number of nodes without interrupting business operations, improving scale and reducing operational costs. At the same time, the risks of node split-brain in large-scale deployments, where nodes are out of sync or processing conflicting data, are significantly reduced.
The benefits of this architecture are leveraged in EMQX Cloud, our fully managed MQTT Cloud service. Our EMQX Kubernetes Operator implements this new architecture for improved automated deployment and scalability.

The MQTT protocol is commonly used for messaging services in the IoT and Internet of Vehicles (IoV) applications. It is designed to work on top of a transport protocol that provides a reliable, ordered, and lossless stream of bytes in both directions. This reliable transport protocol guarantees that messages are delivered accurately and in the order they were sent. Traditionally, IoT applications apply MQTT over TCP-based protocols, such as raw TCP, TCP/TLS (for security), and WebSocket (for web browser adaption). However, there are limitations in scenarios where wireless networks do not provide consistent coverage, causing high latency and packet loss. MQTT over QUIC provides reliable messaging over wireless networks with poor connectivity or low bandwidth.
QUIC, initially developed by Google, was later adopted as a worldwide standard by the Internet Engineering Task Force (IETF). QUIC is the underlying transport protocol of the next-generation internet protocol HTTP/3. QUIC communicates over the UDP instead of the TCP protocol. Compared to TCP/TLS protocols, QUIC provides efficient and flexible transport layer capabilities while reducing connection overhead and message latency, it is well-suited for modern mobile internet like IoT and IoV.
EMQX Enterprise is the first product that combines QUIC with the MQTT protocol. Through extensive customer service and technological exploration, we have observed that the features of QUIC perfectly address challenges common in IoT environments, such as weak network conditions and unstable network paths. As a result, we integrated QUIC into the transport layer of MQTT and designed unique message transmission mechanisms and management methods. This diagram shows the Application, Transport, and Network layers of the IP protocol stack when using MQTT over QUIC. Note that MQTT over QUIC uses UDP instead of TCP.
EMQX Enterprise 5.1 introduces MQTT over QUIC, a breakthrough solution that outperforms TCP/TLS in multiple comparative tests. This powerful combination addresses the challenges faced by IoT workflows that demand constant mobility, such as connected vehicles or devices with periodic sleep requirements.
MQTT over QUIC has undergone extensive testing and integration within the EMQX Enterprise user base, receiving positive feedback. As a member of OASIS, EMQ is also actively promoting the standardization of MQTT over QUIC. Customers in the connected vehicle and mobile data collection can leverage the latest developments and standardized protocols.

EMQX's MQTT-based file transfer functionality is designed for seamless integration without modifying existing clients and applications. Compared to HTTP/FTP protocols, MQTT has the advantage of low bandwidth consumption and minimal resource usage, enabling fast and efficient file transfers. The unified IoT data channel simplifies system architecture, reducing application complexity and maintenance costs.
EMQX incorporates advanced data integration capabilities through its rule engine and data bridging functionality. This allows real-time processing of IoT data and seamless integration with third-party data systems, including Kafka, AWS RDS, MongoDB, Oracle, and popular time series databases like TimescaleDB and InfluxDB.
In EMQX Enterprise 5.1, we have further improved these capabilities by visualizing data integration workflows. With easy-to-understand visualizations of your data integrations in our dashboard, you can achieve effortless application integration and drive business innovation.
In previous versions, configuring data integration involved working with SQL and rule actions, which required familiarity with SQL syntax. Managing and maintaining data processing and integration flows without visibility became challenging when dealing with numerous rules. This increased the development cost and configuration complexity.
EMQX Enterprise 5.1 addresses these challenges by introducing a visual Flows page, where users can easily view the data processing rules and the integration with third-party data systems for each topic in our dashboard.
Use our dashboard to monitor the status of each step of your data flow in real-time.
EMQX Enterprise 5.1 extends bi-directional data bridging capabilities. Devices can bridge data to external systems, while data from external sources like MQTT services or Kafka, can also be bridged to EMQX. After undergoing rule processing, the data is then sent to designated devices. What does this mean? More efficient use of the network! Our EMQX rules engine will filter incoming messages and only publish the messages that you choose to deliver to clients. This unique rules engine can greatly reduce the amount of unnecessary data sent over the network.
This is perfect for cloud-to-device scenarios, enabling real-time processing of IoT data using a unified language while supporting continuous large-scale message delivery. The EMQX rules engine opens up new possibilities for IoT business development.
