Agenda

Introduction to Bluemix

Application Messaging

Introduction to MQ Light Service

The next billion

dollar idea starts

with a single

developer.

That developer

starts with a single

line of code

IBM BlueMixDelivering a Composable Services development environment

Run Your AppsThe developer can chose any language runtime or

bring their own. Just upload your code and go.

DevOpsDevelopment, monitoring, deployment and

logging tools allow the developer to run the

entire application

APIs and ServicesA catalog of open source, IBM and third party

APIs services allow a developer to stitch

together an application in minutes.

Cloud IntegrationBuild 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 SoftLayerRuns automatically on top of IBM’s leading

infrastructure as a service. No need to worry

about provisioning or managing infrastructure.

Agenda

IBM Messaging portfolio

Deliver Messaging Backbone for EnterpriseFocus on traditional MQ values, rock-solid enterprise-class service, ease-of-operation, breadth of platform coverage, availability, z/OS exploitation

Capture Big Data from Mobile and Internet of ThingsFocus on Internet-scale events, m2m device enablement, security and privacy, feed into real-time analytics, location-based notifications

Enable developers to build more scalable, responsive applicationsFocus on application developer use cases, breadth of language support, no administration, ease-of-deployment, lightweight & powerful API, as software or a cloud service

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

The journey that got us here…

Centrally planned IT Architecture

Emerges:

Business sponsor driven

Developer led architecture

Developers select tools to get the job done

Focused on trying new apps and concepts in

the market

Centrally controlled common standards

Planned projects delivering core systems

Focused on skills and investment reuse

The journey that got us here…

Node.js

Python

Clojure

Erlang Scala

Use Cases

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

Worker Offload

Use Cases

Schedule a task to happen at a specific point in

- Run in detailed reports when app use is low

- Generate end of day summary

Ensure applications remain responsive even when

3rd party system are not available or responding

fast enough

- Updating existing CRM system

- Booking appointment

Delayed Processing

3rd Party Integration

•Test, deploy, operate as a whole.

•Often Scale monolithic app

•Powerful integration runtimes.

•Homogeneous technologies

•Small empowered dev-ops teams own each

service.

•Test, deploy, monitor, operate individual

services.

•Polyglot languages & persistence.

•Services scale automatically as needed.

Agenda

MQ Light with Node.js using MQ Light API

Simple, programming Language neutral messaging model

Idiomatic language & framework API Mappings

• Frictionless development

Open wire protocol (AMQP 1.0) & Open Source client libraries

• Facilitates community drivers for languages & frameworks

MQ Light API

Priority based on

feedback.

MQ Light with Java

JMS 1.1 API

• Pub/Sub and Queue

• Local Transactions only.

• Java SE model

• Java EE Model including MDBs

JMS JMS

MQ Light

Polyglot Messaging

Mapping from JMS to MQ Light enables apps using polyglot

model.

Worker offload with workers implemented in different

languages.

MQ Light

……

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?

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

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

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

MQ Light Messaging Model – Persistent destinations

•Destinations persist for a defined “time to live” after receiver detaches.

Topic Address Space

Sender application

World!

DESTINATION

Pattern=/test/a

Disconnected client

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

Topic Address Space

Sender application

DESTINATION

Pattern=/test/#

Share=myshare

Client 1

Client 2

Client 3

MQ Light Messaging Model – Client takeover

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 Messaging Model

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)

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.

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 JMS Support

Support “Java SE” style messaging.

• The WMQ classes for JMS now contain a provider service for

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

JmsFactoryFactory ff = JmsFactoryFactory.getInstance(JmsConstants.MQLIGHT_BLUEMIX_PROVIDER);

ConnectionFactory cf = ff.createConnectionFactory();
