**Intent:** When applications communicate using a messaging system they do it by using logical addresses
|
||
|
|
of the system, so called Publish Subscribe Channel. The publisher broadcasts a message to all registered Subscriber.
|

|
|
||
|
|
|
||

|
**Applicability:** Use the Publish Subscribe Channel pattern when
|
||
|
|
|
||
|
|
* two or more applications need to communicate using a messaging system for broadcasts.
