EMQX Overview
EMQX is an open-source, highly scalable, and feature-rich MQTT broker designed for IoT and real-time messaging applications. It supports up to 100 million concurrent IoT device connections per cluster while maintaining a throughput of 1 million messages per second and a millisecond latency.
EMQX supports various protocols, including MQTT (3.1, 3.1.1, and 5.0), HTTP, QUIC, and WebSocket. It also provides secure bi-directional communication with MQTT over TLS/SSL and various authentication mechanisms, ensuring reliable and efficient communication infrastructure for IoT devices and applications.
With a built-in powerful SQL-based rules engine, EMQX can extract, filter, enrich, and transform IoT data in real-time. EMQX also ensures high availability and horizontal scalability with a masterless distributed architecture and provides an operations-friendly user experience with excellent observability.
EMQX has been adopted by over 20,000 enterprise users, connecting more than 100 million IoT devices. Over 400 customers, including renowned brands like HPE, VMware, Verifone, SAIC Volkswagen, and Ericsson, trust EMQX for their mission-critical IoT scenarios.

Use Cases
As an MQTT broker designed for IoT and real-time messaging applications, EMQX is often used to fulfill various business requirements in the following scenarios.
Reliable and Efficient Pub/Sub Messaging
EMQX supports multiple protocols, including MQTT (3.1, 3.1.1, and 5.0), HTTP, QUIC, and WebSocket. It also provides secure bi-directional communication with MQTT over TLS/SSL and various authentication mechanisms, ensuring reliable and efficient communication infrastructure for IoT devices and applications.
Using EMQX in mission-critical applications brings you key benefits as follows:
- Topic-Based Pub/Sub Messaging: EMQX's topic-based publish/subscribe model streamlines the data flow to ensure efficient and flexible message routing.
- Ultra-Low Latency Delivery: Achieve rapid data transfer with latencies as low as 1 millisecond, ensuring real-time responsiveness.
- Comprehensive Quality of Service (QoS) Guarantees: EMQX offers end-to-end multi-level QoS guarantees, providing reliable and flexible message delivery.
EMQX can help you in various scenarios listed below.
Peer-to-Peer Communication
You can build up peer-to-peer communications with EMQX. In the asynchronous Pub/Sub model, the message publisher and subscriber are decoupled from each other, as they can be dynamically added or removed as needed. This decoupling provides flexibility to your applications and message communication.
Message Broadcasting to a Large Audience
EMQX excels in scenarios where one-to-many messaging is vital, such as financial market updates. It effectively broadcasts messages to a large number of clients, ensuring timely information dissemination.
Data Consolidation from Massive Endpoints
The many-to-one message pattern in EMQX is ideal for consolidating data in large-scale networks, such as factory plats, modern buildings, retail chains, or electricity grids. EMQX can help you transfer and transmit the data from the endpoints in the network to your centralized backend servers on the cloud or on-premise.
Traceable Communication with Request-Response Awareness
EMQX supports the MQTT 5.0 feature Request-Response. With this feature, you can now increase communication awareness and traceability in your asynchronous communication architect.
Data Integration Across Different Networks
In a partitioned, or limited network environment, EMQX can create the data integrations, provide you with a seamless messaging environment.
Flowing Data Transformation
With a built-in powerful SQL-based rules engine, EMQX can extract, filter, enrich, and transform the flowing data in real-time. Processed ata can be easily ingested into external HTTP servers and MQTT services. If you are using EMQX Enterprise, you can also ingest data into mainstream databases, data storage, and message queues.
