+**Intent:** When two applications communicate using a messaging system they do it by using logical addresses
+of the system, so called Message Channels.
+
+
+
+**Applicability:** Use the Message Channel pattern when
+
+* two or more applications need to communicate using a messaging system

+/**
+ *
+ * When two applications communicate with each other using a messaging system
+ * they first need to establish a communication channel that will carry the
+ * data. Message Channel decouples Message producers and consumers.
+ *
+ * The sending application doesn't necessarily know what particular application
+ * will end up retrieving it, but it can be assured that the application that
+ * retrieves the information is interested in that information. This is because
+ * the messaging system has different Message Channels for different types of
+ * information the applications want to communicate. When an application sends
+ * information, it doesn't randomly add the information to any channel available;
+ * it adds it to a channel whose specific purpose is to communicate that sort of
+ * information. Likewise, an application that wants to receive particular information
+ * doesn't pull info off some random channel; it selects what channel to get information
+ * from based on what type of information it wants.
+ *
+ * In this example we use Apache Camel to establish two different Message Channels. The first
+ * one reads from standard input and delivers messages to Direct endpoint. The second Message
+ * Channel is established from the Direct component to console output. No actual messages are sent,
+ * only the established routes are printed to standard output.
