## What it is
RabbitMQ is an open source, multi-protocol messaging and streaming broker supporting AMQP 0-9-1, AMQP 1.0, MQTT, STOMP, and its Streams protocol. It provides reliable message queuing, routing, clustering, and replication for distributed applications, with a Kubernetes cluster operator and client libraries in many languages.

## Use cases
- queue messages between microservices
- publish-subscribe event distribution
- decouple background job processing
- stream high-throughput events to consumers
- connect IoT devices over MQTT
- reliable message delivery with acknowledgments and replication

## When to choose
- you need a mature, battle-tested message broker with rich routing semantics
- you need multi-protocol support (AMQP, MQTT, STOMP, streams) in one broker
- you need clustering, replication, and quorum queues for data safety
- you want broad client library support across languages

## When to avoid
- you only need simple fire-and-forget notifications where a lighter tool suffices
- you need long-term event storage and replay at massive scale where a log-based system like Kafka may fit better
- you want a fully managed service without operating a broker

## Facets
- artifact type: service
- maturity: stable
- function: message-queue, streaming, monitoring, middleware
- domain: microservices, iot, developer-tools
- platform: windows, self-hosted, cloud
- tags: amqp, mqtt, stomp, message-broker, streams, erlang, event-driven-architecture, pub-sub, messaging, linux, macos, docker, kubernetes
