RabbitMQ

RabbitMQ is a robust, open-source messaging and streaming broker designed for reliable communication between applications. It implements the Advanced Message Queuing Protocol (AMQP) and supports protocols like MQTT, making it interoperable with diverse systems. It facilitates asynchronous communication patterns crucial for microservices architectures, real-time data streaming, and IoT applications. Messages are routed and filtered based on flexible rules, ensuring delivery to the correct consumers. The broker offers message acknowledgment and clustering for high availability and fault tolerance. It is deployable on-premises, in the cloud, or locally, making it a versatile solution for various infrastructure setups. It ensures messages are safely delivered even during network interruptions or service downtime by queueing them until consumers are available. Commercial support is available through VMware Tanzu, offering enhanced features and support for mission-critical applications.
