AMQP and 0MQ are Message Queues.

Roughly (I'm no authority) MQ's are associated with finance for a few reasons:
 1. Message orientation
 2. Often good for building high availability systems on cheap
hardware (n:n topology support)
 3. Can be very low latency and bandwidth efficient
 4. (probably) 'Enterprise' cultural overhead

Code-wise, you can typically use the sockets interface to connect to
them but they have all sorts of their own options to expose their
flexibility.  Often reliability is optional - in part, it's this
ability to switch off the service guarantees provided by a standard
transport that lend these layers their power, the other side being
topology flexibility.

In any case, message queues definitely appear to be a (the?) primary
potential transport option for non "vendor locked-in" financial
systems today.

Hope that clarifies.
