This document discusses messaging in the cloud using IBM MQ Light and IBM Bluemix. It provides an overview of Bluemix and its capabilities for running applications. It then discusses application messaging and introduces the MQ Light service. The rest of the document demonstrates MQ Light, including its messaging model, programming interfaces for different languages like Node.js and Java, and tooling support. It emphasizes the ease of use of MQ Light for building scalable and responsive cloud applications.

5. IBM BlueMix
Delivering a Composable Services development environment
© 2014 IBM Corporation
Run Your Apps
The developer can chose any language runtime or
bring their own. Just upload your code and go.
DevOps
Development, monitoring, deployment and
logging tools allow the developer to run the
entire application
APIs and Services
A catalog of open source, IBM and third party
APIs services allow a developer to stitch
together an application in minutes.
Cloud Integration
Build hybrid environments. Connect to on-premises
systems of record plus other public and
private clouds. Expose your own APIs to your
developers.
Built on IBM SoftLayer
Runs automatically on top of IBM’s leading
infrastructure as a service. No need to worry
about provisioning or managing infrastructure.

MQ Light : Software and Cloud
 Messaging that application developers will
love to use, helping them make responsive
applications that scale easily
 3 ways to get it:
– Bluemix service
– MQ Light software download
– Statement of Direction for support in MQ Version 8.
 Open APIs crafted to feel natural in a
growing range of popular languages
 Tooling that makes modular app
development easy

Use Cases
11
Worker Offload
Intensive work offloaded and distributed
amongst worker processes to be performed
asynchronously
- Processing images or videos
- Performing text analytics
Event Driven
Take one or more actions when something
interesting happens
- Email logs and update dashboards when build finishes
- Upload videos once finished transcoding

12. © 2014 IBM Corporation
Use Cases
12
Delayed Processing
Schedule a task to happen at a specific point in
time
- Run in detailed reports when app use is low
- Generate end of day summary
3rd Party Integration
Ensure applications remain responsive even when
3rd party system are not available or responding
fast enough
- Updating existing CRM system
- Booking appointment

20. Tooling to assist development
Used to answer questions like :
• Where did this message come from?
• Where did that message go?
• What messages has my app consumed?

21. MQ Light Messaging Model – Send Messages
Applications send messages to a topic.
A topic is an address in the topic space
either flat or arranged hierarchically.
21
© 2014 IBM Corporation
1. Send (‘/test/a’, “Hello”);
2. Send (‘/test/a’, “World!”);
Topic Address Space
Sender application

22. MQ Light Messaging Model – Simple Receive
•Applications receive messages by creating a destination with a pattern
which matches the topics they are interested in.
•Pattern matching scheme based on WMQ.
22
© 2014 IBM Corporation
1. Send (‘/test/a’, “Hello”);
2. Send (‘/test/a’, “World!”);
1. Hello
2. World!
Topic Address Space
Sender application
DESTINATION
Pattern=/test/a

23. MQ Light Messaging Model – Pub/Sub
•Multiple destinations can be created which match the same topic
23
© 2014 IBM Corporation
•Pub/Sub style.
DESTINATION
1. Send (‘/test/a’, “Hello”);
2. Send (‘/test/a’, “World!”);
1. Hello
2. World!
1. Hello
2. World!
Topic Address Space
Sender application
DESTINATION
Pattern=/test/a
Pattern=/test/#
Client 1
Client 2

24. MQ Light Messaging Model – Persistent destinations
•Destinations persist for a defined “time to live” after receiver detaches.
24
© 2014 IBM Corporation
1. Send (‘/test/a’, “Hello”);
2. Send (‘/test/a’, “World!”);
Topic Address Space
Sender application
Hello
World!
DESTINATION
Pattern=/test/a
Disconnected client

25. MQ Light Messaging Model – Sharing
1. Send (‘/test/a’, “Hello”); DESTINATION
2. Send (‘/test/a’, “World!”);
•Clients attaching to the same topic pattern and share name attach to the
same shared destination.
25
© 2014 IBM Corporation
1. Hello
2. World!
1. Hello
2. World!
SHARING
Topic Address Space
Sender application
DESTINATION
Pattern=/test/#
Pattern=/test/#
Share=myshare
Client 1
Client 2
Client 3

26. MQ Light Messaging Model – Client takeover
26
© 2014 IBM Corporation
1. Send (‘/test/a’, “Hello”);
Hello
Topic Address Space
Sender application
DESTINATION
Pattern=/test/#
Client 1
World!
Client 1
2. Send (‘/test/a’, “World!”);
•Applications connect to MQ Light service specify (optional) client ID.
•Re-using the same client ID pre-empts the original connection.
•Ideal for worker takeover in the cloud.

27. MQ Light Messaging Model
© 2014 IBM Corporation
Messages
• Payload is either Text or Binary.
• Content-type is used by clients to transfer JSON
• Per message time to live.
Message delivery model
• At most once delivery (QoS 0)
• At least once delivery (QoS 1)
• Acknowledge & Reject messages
• Control over the number of unacknowledged messages
delivered. (link credit)
27

28. MQ Light Node.JS API.
Installable from NPM
Promotes a fluent programming style
Easily wrappable into promises.
Focussed on code simplicity.
Client - connect state machine
• Assists cloud applications.
28
© 2014 IBM Corporation
client.connect()
.on('connected', function() {
console.log('Have some random cat names. Have them!');
subscribe('/kittens');
})
.on('disconnected', function() {
console.log('That's enough for now!');
})
.on('message', function(data) {
console.log('Why not call your cat: '+data);
});

29. MQ Light Service JMS Support
Support “Java SE” style messaging.
• The WMQ classes for JMS now contain a provider service for
JmsFactoryFactory ff = JmsFactoryFactory.getInstance(JmsConstants.MQLIGHT_BLUEMIX_PROVIDER);
ConnectionFactory cf = ff.createConnectionFactory();
© 2014 IBM Corporation
Bluemix.
• Include WMQ Classes & Push the app to bluemix as .jar
Supports Liberty Profile “JEE” style messaging.
• Either push a .WAR
– Resource Adapter injected and JNDI namespace populated by
Liberty buildpack.
• Or push a packaged liberty server
– Supports MDBs
