message bus

There are actually quite a few ways to implement a message bus, as well as quite a few vendor tools designed to make it easier.

A message bus is a collection of message channels (also known as a queue or topic) usually configured as request-reply channel pairs.

What makes it interesting here, however, is the fact that the message is actually sent to a destination on the message bus.

The message bus creates an event object and dispatches it, along with an instance of a business service, to an event channel.

Each message is published, along with an asynchronous callback listener, to a message bus residing on the business tier.

The material covered in this installment has provided only a cursory glance at the basic implementation of the message bus pattern.

It is not enough to just start the application after it has been installed because the message bus will not start.

So, is an ESB just a message bus?

This particular component's goal is to demonstrate the inherent flexibility of the message bus model.

Azure AppFabric is a message bus, with the goal of making authentication and message passing easier, especially across firewalls.

Together these products provide a robust, enterprise-quality message bus architecture that meets the needs of most business cases.

Channels move messages either into or out of the message bus.

Each business application is a peer of the others through the event-driven message bus.

The message bus may include a message broker that determines where messages will be routed depending on various business criteria.

The design leverages RTI 's message bus to implement a hierarchical control network with well controlled data-flows.

Standards and patterns exist today for implementing a synchronous ESB and a message bus that is a simplified asynchronous ESB.

The message bus component is primarily comprised of one or more individual channels through which messages can be passed.

This message bus is the gist of an ESB, and this is nothing new.

In message-oriented-middleware (MOM) -style infrastructures, the message bus pattern is the single most important architectural design.

An xSB, enterprise or otherwise, is for invoking services; or else it's simply a message bus.

D-BUS is an up-and-coming message bus and activation system that is set to achieve deep penetration in the Linux desktop.

The message bus daemon forms the hub of a wheel.

A shortcoming of the traditional message bus approach is that it's not self-describing.

We will also look at the setup needed to send the JMS message through the message bus in the application server.

The ESB, however, encorages the use of the asynchronous message bus style interaction pattern illustrated in Figure 4 earlier.

Applications communicate with the message bus through one or more channels.

So if a message bus is not a full ESB, then what else does an ESB do?

In creating this application, we will see the setup that is needed to send a JMS message through the message bus in the application server.

The final application component plugged into the message bus is a simple console application that displays
