Architecture of Message Oriented Middleware [1]

[2] Middleware Middleware is the software that assists an application to interact or communicate with other applications, networks, hardware, and/or operating systems.

Types of Middleware Types:-  Message-Oriented Middleware (MOM)  Transaction Processing Monitors (TPM)  Remote Procedure Calls (RPC)  Object Request Brokers (ORB) [3]

Message Oriented Middleware Message Oriented Middleware (or “MOM”) is one particular form of middleware, which is capable of facilitating the transportation of asynchronous messages from one component to another. [4]

[5] Example implementations of MOM are Sun’s JMS,Microsoft’s MSMQ, and IBM’s MQSeries. Forms of MOM:- (i) “Message Queuing” (ii) “Publish-Subscribe” Forms of MOM

Message Queuing [6]

Publish-Subscribe [7]

Implementations of MOM JMS:-  Java Message Service is a part of Sun's J2EE suite, which provides a standard set of APIs that developers can use to access the features of any underlying messaging system.  It supports both the Publish/Subscribe as well as the Point-to-Point (Message Queuing) models.

MSMQ  MSMQ is Microsoft’s implementation of MOM.  Messages are typically kept in queues that are managed by Queue managers. [11]

Key Points About MSMQ [12] MSMQ MSMQ Enterprise Message Delivery SitesMQIS

MSMQ Queues  Two types of queues in MSMQ. 1)Public queues 2)Private queues  Systems within the MSMQ Enterprise are classified into Servers, Dependent Clients and Independent Clients. [13]

MQSeries  IBM’s implementation of MOM  Objects:- The word “object” refers to the “things” that have to be set up after the product is installed.  Types:- 1) Queue Manager 2) Queue 3) Channel [14]

Communication is undoubtedly one of the most prominent and essential requirements in software systems, especially those that are highly distributed, and MOM is playing an important role in ensuring this vital need. [18] Conclusion
