PEACE OF MIND
“I am losing talented developers because they
don’t have access to the tools they want to use.”
“I am nervous we are spending time and money
integrating things that should naturally fit together”
“My average developer has 250 open change
requests from the business. That is a lot of business
value we need to deliver”
“I am not confident that the platform is secure as I
integrate into existing systems”

Corporation
Translates into an application development
environment that…
Brings the best of born-on-the-cloud development
without leaving behind enterprise data and
services
Combines the flexibility of a platform as a service
(PaaS) with existing suites of software as a
service (SaaS)
Offers freedom of choice to use any software or
open technologies
Scales from a single developer to global teams
Enables a massive and open ecosystem built on
open standards

Delivering a Composable Services development environment
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.

What is MQ Light and Application Messaging?
Messaging for application developers to help
create responsive applications that scale
easily
Trivially easy to get started;
no setup, no configuration, no administration
Available as software download or full cloud
service in IBM Bluemix
APIs crafted specifically for each language
Tooling that supports app development
Cloud Service

Use Cases
16
Worker Offload
Intensive work offloaded and distributed
amongst worker processes to be
performed asynchronously
Examples :
Processing images or videos
Performing text analytics
Event driven
Take one or more actions when
something interesting happens
Examples:
●
Email logs and update dashboards when
build finishes
●
Upload videos once finished transcoding

© 2014 IBM
Corporation
Use Cases
17
Delayed processing
Schedule a task to happen at some
point in the future
Examples :
●
Generate end of day summary
●
Run detailed report when app usage
is low
3rd party integration
Connect to 3rd
party system and ensure
applications remain responsive even
when 3rd
party is not available or
responding fast enough
Examples
●
Updating existing CRM system
●
Booking appointment

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.
1. Send (‘/test/a’, “Hello”);
2. Send (‘/test/a’, “World!”);
Topic Address Space
Sender application

27
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.
1. Hello
2. World!
Topic Address Space
Sender application
DESTINATION
Pattern=/test/a

© 2014 IBM
Corporation
28
MQ Light Messaging Model – Pub/Sub
• Multiple destinations can be created which match the same topic
• Pub/Sub style.
DESTINATION
1. Hello
2. World!
1. Hello
2. World!
Topic Address Space
Sender application
DESTINATION
Pattern=/test/a
Pattern=/test/#
Client 1
Client 2

© 2014 IBM

29
MQ Light Messaging Model – Persistent destinations
• Destinations persist for a defined “time to live” after receiver detaches.
Topic Address Space
Sender application
Hello
World!
DESTINATION
Pattern=/test/a

Corporation
30
MQ Light Messaging Model – Sharing
• Clients attaching to the same topic pattern and share name attach to
the same shared destination.
DESTINATION1. Send (‘/test/a’, “Hello”);
1. Hello
2. World!
1. Hello
2. World!
SHARING

MQ Light Messaging Model - Message Delivery
Currently:
– At most once delivery (QoS 0)
– At least once delivery (QoS 1)
On the backlog:
• Acknowledge & Reject messages
• Control over the number of unacknowledged messages
delivered. (Readahead)
• require Destination – Results in a error if a destination
does not exist for the message.

© 2014 IBM
Corporation
MQ Light Messaging Model – Messages
Messages have a payload which is either Text or Binary.
• Content-type is used by clients to transfer JSON
On the backlog:
• Messages can have:
– Time-to-live
– Delivery delay
– Properties
32

MQ Light Messaging Model – Client takeover
Hello
Topic Address Space
Sender application
DESTINATION
Pattern=/test/#
Client 1
World!
Client 1
• 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.

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.
34
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);
});

MQ Light Service (Beta in IBM Bluemix)
Supports MQ Light API & JMS
JMS queues autodefined to
minimize administration
Connection details supplied
to app by VCAP_SERVICES
Location transparency facilitated
by “connectionLookupURI”
– Default URI returns list of
endpoints as json document
– JMS connections append
“&format=CCDT” to get CCDT
Client Libraries injected into application runtime
– Node.JS - Specify dependency on mqlight in package.json
– Java JEE – Resource adapter added when JMS is detected by Liberty
buildpack.

MQ Light Service Node.js Support
Applications can be developed and tested locally by connecting
to local server, then seamlessly deployed into Bluemix
– Must be coded to read connection details from
VCAP_SERVICES
38
require "mqlight"
var opts;
if (process.env.VCAP_SERVICES) {
var services = JSON.parse(process.env.VCAP_SERVICES);
if (services[ 'mqlight' ] != null)
{
username = services [ 'mqlight' ][0].credentials.username;
password = services [ 'mqlight' ][0].credentials.password;
connectionLookupURI = services['mqlight'][0].credentials.connectionLookupURI;
}
opts = { user: username , password: password, service: connectionLookupURI , id:id};
} else {
opts = { service:'amqp://localhost:5672',id:id};
}
var client = mqlight.createClient(opts);
client.connect(function(err)

Corporation
MQ Light JMS Support
Support “Java SE” style messaging.
• Either read connection details from VCAP_SERVICES
• Or use the connection helper
• Include the WMQ JMS client libraries
• Push 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 39
MQLightConnectionHelper connHelper = MQLightConnectionHelper
.getMQLightConnectionHelper();
MQConnectionFactory cf = (MQConnectionFactory)connHelper.getJmsConnectionFactory();
Connection conn = cf.createConnection(connHelper.getUsername(),
connHelper.getPassword());
