Investment banks typically consolidate distribution of real-time market data from stock exchanges and new services to a centralize department and infrastructure. This market data infrastructure then supplies data to the trading floors and trading application systems and to general purpose users throughout the bank. In addition many banks also support their external customers as well. The requirement for low latency high throughput messaging is well documented in this use case.

Example case: Merrill Lynch has publicly endorsed the Wombat infrastructure running on 29West's LBM messaging product. This infrastructure is in place at numerous banks around the world.
