4. Message Broker
• Component of « MOM », Message Oriented Middleware
• An architectural pattern for message validation,
transformation and routing.
• Mediate communication amongst applications,
minimizing the mutual awareness that application should
have of each other, effectively implementing decoupling
 Integrate applications without enforcing a common
interface

5. Purpose
• Route messages to one or more of many destinations (unicast / multicast)
• Transform messages to an alternative representation (mapping)
• Perform message aggregation, decomposition/recomposition of messages
• Respond to events or errors (“triggering”)
• Provide content and topic-based message routing using the publish–
subscribe pattern.

8. AMQP
•
Some key AMQP messaging protocol requirements
– Internet protocol - like HTTP, TCP –
but ASYNCHRONOUS
– Where to send messages (Routing)
– How to get there (Delivery)
– What goes in must come out (Fidelity)
- Each message is stateless
- Consumers create queues; these
buffer messages for push to consumers
- Queues are stateful, ordered, and can
be persistent, transient, private, shared.
- Exchanges are stateless routing
tables.

9. RabbitMQ
•
Implements AMQP
•
Written in Erlang, a functional language known for its ability for concurrent
processing, and backed by Mnesia, Erlang’s powerful persistence database.
•
Used by NASA’s Nebula Cloud Computing Platform, VMWare, AT&T
Interactive, Digg, BBC, Nokia and ….

12. What about SQL Server Service Broker?
SQL Server Service Broker :
- native support for messaging and queuing applications
- use the Sql Server Database Engine components to communicate between
disparate databases.
- handles the communication paths in the context of transactioned conversation.
