The document provides an overview and introduction to IBM's MQ Light service on Bluemix. Some key points: - Bluemix is IBM's cloud platform that allows building, running, and managing applications. It provides services, tools for development and management, and flexible pricing models. - MQ Light is a messaging service designed for application developers to create responsive and scalable applications. It has a simplified API and supports multiple programming languages. - The demo section shows how to use the MQ Light service on Bluemix to send and receive messages from Node.js, Java, Ruby, and Python applications. It also integrates with services like Node-RED.

Bluemix is an open-standards, cloud-based platform for building,
running, and managing applications.
Build your apps, your way
Use the most prominent
compute technologies to
power your app: Cloud
Foundry, Docker, OpenStack.
Extend apps with services
A catalog of IBM, third party,
and open source services
allow the developer to stitch
an application together
quickly.
Scale more than just
instances
Development, monitoring,
deployment, and logging
tools allow the developer to
run and manage the entire
application.
Layered Security
IBM secures the platform and
infrastructure and provides you
with the tools to secure your
apps.
Deploy and manage hybrid
apps seamlessly
Get a seamless dev and
management experience
across a number of hybrid
implementations options.
Flexible Pricing
Try compute options and
services for free and, when
you’re ready, pay only for what
you use. Pay as you go and
subscription models offer
choice and flexibility.

4. Single tenant hardware that’s completely dedicated to you – allowing
you to satisfy regulatory & legal compliance.
Dedicated
Public
Local
• The Bluemix platform and dedicated
runtimes and services sit on SoftLayer
hardware that is dedicated to you
• You still have the ability to connect to all
multi-tenant services in the “public”
catalog
• Integrated to your LDAP for developer
authentication
• Elastic capacity based on your demands.
What it means
Dedicated to you

6. IBM Messaging
Deliver Messaging
Backbone for Enterprise
Focus on traditional MQ
values, rock-solid
enterprise-class service,
ease-of-operation, breadth
of platform coverage,
availability, z/OS
exploitation
Enable Developers to
build more scalable,
responsive applications
Focus on app use cases,
breadth of languages,
ease-of-deployment, micro
services, integration with
developer frameworks

7. 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

10. Trend towards cloud native microservices
Development teams
Delivering global scale applications with
unprecedented agility using a
microservices architecture
Challenges developing microservices :
Agility come from “2 pizza” teams operating completely
independently, owning the whole technology stack,
deploying on their own schedules, writing services
that will scale when demand dictates
Cloud messaging delivers :
Self service cloud messaging accessible from any language
Open standards are essential; guaranteeing full stack architects complete freedom
Reactive scaling
The infrastructure must scale up to any conceivable load
Application controlled messaging
Eradicates coordination of configuration changes alongside with new service versions
9

11. Different messaging requirements
Messaging for enterprise central IT
• Support for enterprise language and
frameworks
• XA 2 phase transactions and bulletproof QoS
options eliminates app compensation logic.
• Translation between different platform types
• Admin policy controlled behaviour
• Comprehensive configuration options for fine
grained control
Messaging for microservice devs
• Reactive scaling
• Open and standard protocols
• Completely self service
• Application controlled behaviour
• Ability to quickly unit-test microservices
• Minimal concepts for “full stack architects”

16. Introduction to MQ Light Service

17. 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?
16

18. 17
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

19. 18
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. Send (‘/test/a’, “Hello”);
2. Send (‘/test/a’, “World!”);
1. Hello
2. World!
Topic Address Space
Sender application
DESTINATION
Pattern=/test/a

20. 19
MQ Light Messaging Model – Pub/Sub
•Multiple destinations can be created which match the same topic
•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

21. 20
MQ Light Messaging Model – Persistent destinations
•Destinations persist for a defined “time to live” after receiver detaches.
1. Send (‘/test/a’, “Hello”);
2. Send (‘/test/a’, “World!”);
Topic Address Space
Sender application
Hello
World!
DESTINATION
Pattern=/test/a
Disconnected client

22. 21
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. 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

23. 22
MQ Light Messaging Model – Client takeover
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.

24. 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)
