CBDW2014 - Down the RabbitMQ hole with ColdFusion
The document details a presentation by Luis Majano on using RabbitMQ with ColdFusion, covering topics such as messaging patterns, RPC calls, and the AMQP protocol. It highlights the benefits of messaging for application decoupling, scalability, and cross-platform compatibility, as well as discussing various messaging implementations like RabbitMQ. The presentation also includes technical aspects of RabbitMQ operations and provides resources for further learning.

- 2. WHO AM I? •Luis Majano - Computer Engineer • Born in El Salvador ------------------> • Architecture + Software Design • CEO of Ortus Solutions • Manager of the IECFUG (www.iecfug.com) • Adobe Community Professional • Creator of all things Box: ColdBox, ContentBox,WireBox....
- 3. AGENDA • RPC Calls •What is Messaging • Implementations • AMQP Protocol • RabbitMQ • Nice Demo
- 4. RPC STYLE CALLS CFCCFC CFC
- 5. • Blocks RequestUsage • Even if you do them Asynchronous, messages only 1 receiver • Sender always knows about receiver • Receiver knows about sender • How can we decouple knowledge? • How can we apply messaging patterns to our apps? PROBLEMS WITH RPC
- 6. Messaging (EMS) Producer Consumer ConsumerConsumer Messaging Bus Can be any system or language Can be any system or language Doesn’t care about consumers Asynchronous Does not get a response
- 7. • Producers don’tcare about consumers -> Decouple • Cross platforms-technologies-OS, you name it -> Flexibility • Event Driven Programming -> Scalability • Queueing for later delivery • Asynchronous • Load balancing • Hulkyfied services BENEFITS OF MESSAGING

- 10. AMQP - www.amqp.org •Advanced Message Queuing Protocol • != JMS • Standard binary protocol • Exchanges • Queuing • Routing • Reliable • Secure • Several Implementations RabbitMQ ActiveMQ Qpid StormMQ
- 11. • AMQP MessagingBroker • www.rabbitmq.com • Built on erlang like Couchbase NoSQL • Extremely fast, reliable and secure • Languages: c#, erlang, java, python, ruby, node, cfml • Simple concept • Accepts and forwards messages • Its like a post box, post office and postman
- 12. HOW IT WORKS? Producer Message (Body+RoutingKey) Exchange (Bindings via Routing Key) Body = binary, json, anything stock. prices stock. run log. error cluster Queues are bound to exchanges with patterns Routing key = Bindings Queues
- 13. • Direct • Routingkey = queue name • No mapping or extra fluff just a passthrough • Similar to JMS • Topic • Binding pattern (routing key) is match against the queue name • Not full regex • Ex: log.*, log# • Not like JMSTopics, forget JMS, this is not JMS • Fanout + More EXCHANGETYPES
- 14. LOAD BALANCING +ACK Worker Queue Consumer Consumer Consumer Messages are round-robin to each consumer Consumer need to ack
