10. Why do we need messaging?

11. We are about to get a new project give me a prototype

12. will be simple

13. Product owner
come…Notify friends

14. We need to post in
twitter

15. First delivery

16. It take too much
bandwidth…lablabla..
I actually need that yesterday

17. We are going to third-
party integration
PHP
Python
Java

18. UX guys, Customer
feedback
we don’t want to wait

19. We need to build instagram!

20. Poor you (:

21. You play boss killer some time and get back to work

22. All of this the simple solution is
messaging

23. Simple message queue

24. Who are using RabbitMQ?
It is used in the Ocean Observatories Initiative—an
architecture that collects 8 terabytes of data per day.

25. Who are using RabbitMQ?
Instagram
Indeed.com
Telefonica
Mercado Libre
NHS
Mozilla

26. Install RabbitMQ

27. Install in *nix/debian

29. After Install

30. Install Management portal for
RabbitMQ

31. Demo time

34. Hello word

35. var factory = new ConnectionFactory() { HostName = "localhost" };
using (var connection = factory.CreateConnection())
{
using (var channel = connection.CreateModel())
{
channel.QueueDeclare("hello", false, false, false, null);
string message = "Hello World!";
var body = Encoding.UTF8.GetBytes(message);
channel.BasicPublish("", "hello", null, body);
Console.WriteLine(" [x] Sent {0}", message);
}
}
Queue Declare

36. var factory = new ConnectionFactory() { HostName = "localhost" };
using (var connection = factory.CreateConnection())
{
using (var channel = connection.CreateModel())
{
channel.QueueDeclare("hello", false, false, false, null);
var consumer = new QueueingBasicConsumer(channel);
channel.BasicConsume("hello", true, consumer);
Console.WriteLine(" [*] Waiting for messages." +
"To exit press CTRL+C");
while (true)
{
var ea = (BasicDeliverEventArgs)consumer.Queue.Dequeue();
var body = ea.Body;
var message = Encoding.UTF8.GetString(body);
Console.WriteLine(" [x] Received {0}", message);
}
}
}

37. Exchange

51. Easynetq save your time
//many simplification
var bus = RabbitHutch.CreateBus("host=ubuntu:5672,ubuntu:5673");
//also give freedom
var advancedBus = RabbitHutch.CreateBus("host=localhost").Advanced

52. RabbitMQ Features

53. RabbitMQ Features

54. Large Message
Messaging in general should be small
AMPQ support very large messages
RabbitMQ you can use large messages but you need to be careful
MSMQ-Message Queuing is limited
in the size of documents that can
be processed. The maximum size
document that Message Queuing
supports is 4 MB if the document
is in ASCII. The message queue
can handle a maximum of 2 MB if
the document is in Unicode.

55. Buffered and chunked
http://goo.gl/SgnBYf

56. Virtual Hosts

57. Error Handling

58. //no retry
var ea = (BasicDeliverEventArgs) consumer.Queue.Dequeue();
channel.BasicReject(ea.DeliveryTag,false);
//retry
var ea = (BasicDeliverEventArgs) consumer.Queue.Dequeue();
channel.BasicReject(ea.DeliveryTag,true);

59. We cannot retry forever!

60. channel.BasicAck(ea.DeliveryTag,false);
ea.BasicProperties.Headers.Add("RetryHeader",1);
channel.BasicNack(ea.DeliveryTag, false,true);

61. Dead letter queue

62. feelsleepy

63. Clustering and High Availability

64. Demo Environment

65. Sync Erlang cookie

66. 10.10.52.130 debian

67. If erlang version mismatch
Join cluster

69. Demo in management

???

70. Breaking up a cluster
rabbit3$ rabbitmqctl stop_app
Stopping node rabbit@rabbit3 ...done.
rabbit3$ rabbitmqctl reset Resetting node
rabbit@rabbit3 ...done.
rabbit3$ rabbitmqctl start_app
Starting node rabbit@rabbit3 ...done.

71. Distributed Application

72. Shovel plugin
Loose coupling
they may have different users and virtual hosts;
they may run on different versions of RabbitMQ and
Erlang.

73. A process that replicates data
to the remote server

75. Cluster/LAN Cluster/LAN
Shovel
WAN friendly

76. rabbitmq-plugins enable rabbitmq_shovel
rabbitmq-plugins enable rabbitmq_shovel_management
Demo time

77. RabbitMQ Federation

78. Federation Plugin
Loose coupling
WAN-friendly
Specificity
Scalability

79. Federation Plugin

80. RabbitMQ Federation
•Supports replication across different administrative
domains
•Supports mix of Erlang and RabbitMQ versions
•Supports Network Partitions
•Specificity - not everything has to be federated

81. Federated Exchanges

83. Topologies

84. Topologies
Small complete graph

85. Topologies
Fan-out

86. Topologies
Ring

87. Federated Queues

88. rabbitmqctl set_parameter federation-upstream my-upstream
'{"uri":"amqp://admin:admin@192.168.52.133","expires":36000
00}‘
rabbitmqctl set_policy federate-me '^DigitalWorld.'
'{"federation-upstream-set":"all"}' --priority 0 --apply-to
exchanges

sent from another
server.

RabbitMQ

99. RabbitMQ is extremely efficient,
widely deployed & tested
message broker but can hit
performance, if tuned for more
durability and reliability. It’s
more targeted towards serving
enterprise messaging with
advanced routing requirements.
Redis is quick to start,
lightweight & fast broker but
does Not support reliable
delivery Hence can be chosen
for applications where in case
system terminates, losing the
information about tasks for a
few minutes is Not critical.
