What is MOM?

Message-oriented middleware (MOM) is software that connects separate systems in a network by carrying and distributing messages between them.

The features of MOM are as follows:

1. It is a client/server infrastructure that increases the interoperability, portability, and flexibility of an application by allowing the application to be distributed over multiple heterogeneous platforms.
2. It reduces the complexity of developing applications that span multiple operating systems and network protocols by insulating the application developer from the details of the various operating system and network interfaces.
3. MOM is software that resides in both portions of client/server architecture and typically supports asynchronous calls between the client and server applications.
4. Message queues provide temporary storage when the destination program is busy or not connected. MOM reduces the involvement of application developers with the complexity of the master-slave nature of the client/server mechanism.
5. It generally relies on asynchronous message-passing, as opposed to a request-response metaphor.
6. It is one of three categories of connectivity middleware that provide program-to-program communications by message passing.
7. It supports multiple protocols and comprises an infrastructure that will support reliable and scalable high-performance distributed application networks.
8. It is implemented with queued message store-and-forward capability, that is Message Queuing Middleware (MQM).
9. It provides a high performance foundation for application interoperability in diverse and complex environments.
