Implementing a reliable and scalable platform requires powerful and distributed backend. Building a monolithic system is a waste of time and resources, better option will be to build smaller blocks and integrate these services. In my presentation, I will show how to build a modular system and integrate these services. Main area of focus will be queuing systems where RabbitMQ is a leader. In my demo, I will explain what are queuing systems in general, use cases and separation of concern. I will also explain what is AMQP and RabbitMQ, then finish with implementing a project with queuing system.

2. Deeper into RabbitMQ
• What’s a messaging system?
• Message brokers…
• RabbitMQ/AMQP
• Example
• Simulator/Demo

3. What is a messaging system?

4. What is a messaging system?
Message Broker CP

6. RabbitMQ
• A message broker started in 2007
• Acquired and currently developed by Pivotal SoLware
• An AMQP implementaNon in Erlang language
• Has clients in most languages, Java, Python, .Net, Ruby, PHP…etc
• MulNprotocol, AMQP, STOMP, MQTT

7. Advanced Message Queuing Protocol (AMQP)
• Open standard for messaging systems
• Like HTTP, FTP and SMTP, AMQP defines the data format over the wire.
Different implementaNons are interoperable
• Runs on top of TCP, reliable, persistent opNons, high availability, flexible
rouNng, mulNple clients
• Unlike JMS, AMQP is a protocol not an API

8. Advanced Message Queuing Protocol (AMQP)
• Basic concepts
• Exchange
• Queue
• Binding
• RouNng Key
• Exchanges
• Direct
• Fanout
• Topic

9. Advanced Message Queuing Protocol (AMQP)
• Exchange: Direct
Messages with rouNng key:
1. email
2. sms email
sms

10. Advanced Message Queuing Protocol (AMQP)
• Exchange: Fanout
Messages with rouNng key:
1. email
emailemail

11. Advanced Message Queuing Protocol (AMQP)
• Exchange: Topic
Messages with rouNng key:
1. email.thankyou
2. sms.verify
email.thankyouemail.thankyou
sms.verifysms.verify

12. bid.ly
• Post an aucNon
• Subscribe to aucNon channels like “rolex watched” or “ray-ban glasses”
• Receive new aucNons on subscribed channels and start bidding

14. AMQP Reliability
• Publisher (sender) gets a
“confirm” from RabbitMQ
• Subscriber (receiver) send
an “ack” upon successfully
processing the message
• Messages un-acked stay on
rabbit as “unacked” either
unNl subscriber “acks” or
message Nmeouts

17. Summary
• Message brokers
• AMQP, exchange, queue, binding and rouNng keys
• Exchange types, direct, fanout and topic
