Messaging

In this case, integration of applications happens through messaging. One of the applications publishes a message to a message channel that can be accessed by all other applications. Other applications access the message channel and reach the message at some later point in time. The only criteria here is that the applications that are involved should have a predefined agreement on the message channel and the format of the message that is sent to the channel. In the next section, we will dive deep into the concepts of messaging and how enterprise applications can be integrated using the concept of messaging. In the next section, we will dwell deep into the various types of messaging patterns.
