CybusMQ

The Industrial MQTT Broker

CybusMQ is a robust MQTT broker tailored for industrial applications, offering support for both MQTT 5 and MQTT 3.1.1 protocols. It serves as the central message broker within the Connectware ecosystem, facilitating efficient data exchange and inter-service communication.

Key Features

• Industrial-grade stability and scalability: Engineered to withstand the demands of industrial environments, ensuring reliable performance under high-load conditions.

• Cluster mode operation: Designed to run in cluster mode on Kubernetes, enabling horizontal scaling and high availability. By default, it operates with two distinct instances to separate data and control planes, enhancing system organization and reliability.

• Protocol support: Offers services for MQTT, secure MQTT over TLS (MQTTS), and MQTT over WebSockets, providing flexibility in communication methods.

• Usage metrics collection: Gathers usage metrics for reporting to the Portal in online installations, aiding in monitoring and analysis.

• Authentication delegation: Employs web hooks to delegate authentication processes to the Auth Server, ensuring secure access control.

Technical Specifications

• Foundation: CybusMQ is built on VerneMQ, a high-performance distributed MQTT message broker. This foundation provides robust messaging capabilities across distributed systems.

• Technology stack: CybusMQ is written in Erlang, a language optimized for concurrent operations and fault tolerance. The Erlang/OTP virtual machine uses preemptive scheduling, delivering consistent low latency for real-time applications at scale.
