This document discusses message-oriented middleware (MOM). It begins with an introduction to MOM, explaining why it was developed and what it is. Then it covers some common MOM specifications including JMS, AMQP, STOMP, and MQTT. The next section discusses core MOM technologies like transport methods, persistence, and transactions. Advanced features of MOM such as high availability, performance, administration, and plugins are then outlined. Finally, the document briefly introduces alternative messaging technologies like ZeroMQ and cloud messaging before listing references for further information.

MOM spec.
I. JMS
II. AMQP
III. STOMP
IV. XMPP
V. MQTT

4. MOM intro. - why
1970s single protocol connecting mainframe

5. MOM intro. - why
1980s many protocol connecting mainframe

6. MOM intro. - why
• not easy since data format , hardware etc.
• so adapter coms out, but still face many problems,
maintainable?
• so many technologies comes out , such as
RPC(COM/COM+,CORBA,EJB) – sync. call
Message Queue – Async. event notification
Also ,many Enterprise messaging killer coming, such
as WebSphere MQ, SonicMQ , TIBCO Rendezvous,
SUN JCAPS…

7. MOM intro. - what
Message-oriented middleware (MOM) is software or
hardware infrastructure supporting sending and
receiving messages between distributed systems. MOM
allows application modules to be distributed over
heterogeneous platforms and reduces the complexity of
developing applications that span multiple operating
systems and network protocols…
-- From Wikipedia

8. MOM intro. - what
Messaging mediator

9. MOM intro. - when
Heterogeneous application integration
Decoupled between applications(No RPC)
Event-driven backbone(CEP)

10. MOM spec. - JMS
•JMS 1.1 released in in 2002 (JMS 1.0.2 spec. since
1998)
•JMS 2.0 launched in 2011 as JSR 343
•JMS 2.0 released in 2013 (with Java EE 7)

11. MOM spec - JMS
JMS client (MessageProducer, MessageConsumer ,
JMSConsumer , JMSProducer)
Non-JMS client (Instead of the JMS API , using JMS
provider’s native client API)
JMS producer
JMS consumer
JMS provider
JMS message
JMS domains
Administered objects(Connection factory,Destination)

In a way, It’s seems combing memcached protocol with
REST style operation(such as
send,subscribe,unsubscribe,begin,commit,abort,ack,n
ack,disconnect).

Broker performance
 Static scales better than dynamic
 Asynchronous network connection
establishment

No silver bullet...

59. MOM advanced features- Performance

60. MOM advanced features- Performance
Performance differs greatly depending on
many different factors
 the network topology
 transport protocols used
 quality of service
 hardware, network, JVM and operating system
 number of producers, number of consumers
 distribution of messages across destinations along
with message size
So, No one is absolutely winner!
Benchmark testing(SPECjms2007) is a Galileo
thing !

68. MOM geomancy - ZMQ
C++ Networking library
ZMQ Pattern:
Request-reply, which connects a set of clients to a set of services.
This is a remote procedure call and task distribution pattern.
Publish-subscribe, which connects a set of publishers to a set of
subscribers. This is a data distribution pattern.
Pipeline, which connects nodes in a fan-out/fan-in pattern that can
have multiple steps and loops. This is a parallel task distribution
and collection pattern.
