+- A message broker, used for asynchronous message communication between different services.
+- Supports MQTT, AMQP and STOMP, as described below.
+- Messages are sent from a producer to an exchange, which routes it to one or more bound queues, which finally forwards it to one or more consumer.
+- Exchanges can route (1) directly to a specific queue, (2) to multiple queues using topics or (3) to all queues using fanout.
+
+### Messaging Protocols
+
+- Message Queuing Telemetry Transport (MQTT):
+    - Lightweight/minimalistic, designed to avoid excessive communication. Good for IoT environments.
+    - Pub/sub messaging pattern only, with different topics.
+    - Three QoS levels (low-priority 0 to high-priority 2).
+    - Supports a "last will" message specified during client connection setup, that it sent if the client unexpectedly disconnects.
+    - Brokers support retaining the last message on a topic, to send to newly connected clients.
+- Advanced Message Queuing Protocol (AMQP):
+    - Designed as an open standard for enterprise messaging.
+    - Supports sending acknowledgements back from the receiving client to the broker.
+    - Supports reliable message delivery and message persistance.
+    - Uses an _exchange_ in front of a set of _queues_, to allow for more complex routing.
+    - Supports messaging patterns like pub/sub, point-to-pint and request/reply.
+- Simple Text Oriented Messaging Protocol (STOMP):
+    - Designed as a more bare-bones protocol that is simple to implement.
+    - Supports a limited set of commands, including CONNECT, SEND and SUBSCRIBE.
+    - Supports very simple routing.
+    - Is text-based, making implementation and debugging simpler.

     - The maximum response time (MRT) is used in queries to inform hosts about how long the router will wait for a report. Hosts will wait a random amount of time less than the MRT and then sends a report if no other host has sent one yet. This reduces the amount of reports in the local network. IGMPv1 uses a hardcoded value of 10 seconds instead. The maximum configurable value is 25 seconds (255s/10).
