What is pub-sub messaging ?

Answer Posted / deepak meshram

Publish/subscribe (or pub/sub) is an asynchronous messaging
paradigm where senders (publishers) of messages are not
programmed to send their messages to specific receivers
(subscribers). Rather, published messages are characterized
into classes, without knowledge of what (if any)
subscribers there may be. Subscribers express interest in
one or more classes, and only receive messages that are of
interest, without knowledge of what (if any) publishers
there are. This decoupling of publishers and subscribers
can allow for greater scalability and a more dynamic
network topology.

Pub/sub is a sibling of the Message Queue paradigm, and is
typically one part of a larger Message-Oriented Middleware
solution. Most messaging systems support in their API (e.g.
JMS) both the pub/sub and Message Queue models.
