Introduction to MQ Light Service for Bluemix

MQ Light• Messaging API and Graphical tools

MQ Light Service in depth

Demo

3


The next billion dollar idea starts

with a single developer.

That developer starts with a single line of

code

4


New App Culture Has New Expectations

requires new delivery tools

Integrated experience across mobile, internet, storefront and

phoneIntegrated

Mobile is focused on most important functions integrated with

other appsMobile

Iterative delivery has become the norm – users want fewer

functions initially with improvement over timeIterative

Impacts ecosystem of employees and partners as much as

customersEcosystem

5


ELIMINATE DRUDGERY

“It’s not that my developers lack the skills to manage infrastructure, it’s that I don’t want them to. I need them writing code for the business”

OPEN TECHNOLOGIES

ONE SINGLE SOLUTION

EXPERIMENT MORE

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”

…what developers want

6

Challenges that we hear…


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

7


Delivering 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.

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

15

Software


Use Cases

16

Worker Offload

Intensive work offloaded and distributed amongst worker processes to be performed asynchronously

Examples : Processing images or videosPerforming 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


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. Hello2. World!

Topic Address Space

Sender application

DESTINATIONPattern=/test/a


28

MQ Light Messaging Model – Pub/Sub

• Multiple destinations can be created which match the same topic• Pub/Sub style.

DESTINATION


1. Hello2. World!

1. Hello2. World!

Topic Address Space

Sender application


Pattern=/test/#

Client 1

Client 2


29

MQ Light Messaging Model – Persistent destinations

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


Topic Address Space

Sender application

HelloWorld!


Disconnected client


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”);2. Send (‘/test/a’, “World!”);

1. Hello2. World!

1. Hello

2. World!

SHARING

Topic Address Space

Sender application

DESTINATIONPattern=/test/#

Pattern=/test/#Share=myshare

Client 1

Client 2

Client 3


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.

31


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


33

MQ Light Messaging Model – Client takeover

1. Send (‘/test/a’, “Hello”);

Hello

Topic Address Space

Sender application

DESTINATIONPattern=/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.


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 tominimize 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.

37


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)


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());
