WebSphere Message Broker and WebSphere Event Broker belong to a family of business integration products that is available from IBM.
Business integration is the coordination and cooperation of all your business processes and applications. It involves bringing together the data and process intelligence in your enterprise, and harnessing these so that your applications and your users can achieve their business goals.
Business integration means that:
WebSphere MQ messaging provides a secure and far-reaching communications infrastructure that you can expand with WebSphere Message Broker or WebSphere Event Broker to apply intelligence to your business data as it travels through your network.
The main components of WebSphere Message Broker and WebSphere Event Broker (the broker, the Configuration Manager, the User Name Server, and the Message Brokers Toolkit) communicate using WebSphere MQ's communications protocol, WebSphere MQ Enterprise Transport, or, if you implement WebSphere MQ Everyplace, WebSphere MQ Mobile Transport.
Your business applications, which can be on any of more than thirty industry platforms including those from IBM, Microsoft, and Sun Microsystems, Inc., can connect to the broker using WebSphere MQ protocols, or using other protocols, such as WebSphere MQ Telemetry Transport, WebSphere MQ Real-time Transport, WebSphere MQ Multicast Transport, WebSphere MQ Web Services Transport, or WebSphere Broker JMS Transport.
The benefit of using WebSphere MQ protocols (WebSphere MQ Enterprise Transport or WebSphere MQ Mobile Transport) is that they provide assured, once-only delivery of messages between the components.
WebSphere MQ protocols provide rich support for applications:
WebSphere Event Broker provides an optimized publish and subscribe function within a limited WebSphere Message Broker framework. It provides high-performance nonpersistent publish and subscribe functionality to clients that are connected using various transports.
WebSphere Message Broker incorporates WebSphere Event Broker and extends its function to provide a powerful message broker solution driven by business rules. Messages are formed, routed, and transformed according to the rules defined by an easy-to-use graphical user interface (GUI).
Diverse applications can exchange information in dissimilar forms, with brokers handling the processing required for the information to arrive in the right place in the correct format, according to the rules that you have defined. The applications do not need to know anything except their own conventions and requirements.
Applications also have much greater flexibility in selecting which messages they want to receive, because they can specify a topic filter, or a content-based filter, or both, to control the messages that are made available to them.
WebSphere Message Broker provides a framework that supports supplied, basic, functions along with user-defined enhancements, to enable rapid construction and modification of business processing rules that are applied to messages in the system.
WebSphere Event Broker addresses the needs of business and application integration by distributing real-time information from disparate sources of information through a network of access points or a centralized broker. It allows you to:
WebSphere Message Broker addresses the needs of business and application integration by managing the flow of information. In addition to the function of WebSphere Event Broker, it provides services, based on message brokers, to allow you to:
The benefits of WebSphere Message Broker can be realized both within and outside your enterprise:
