Enterprise Service Bus


Over 18 years we have designed, built, and maintained many complex, businesses critical IBM Integration Bus (Message Broker) and MQ systems: multi-segmented systems running numerous Broker nodes, linking to external systems over open internet in a secure manner, efficiently processing hundreds of messages every second. Despite all this complexity, our systems are fantastically robust and reliable; running with no unplanned downtime for many years.

The legendary reliability of IBM’s mainframes makes these machines the preferred choice for customers that requiringe solid 24/7 performance. They scale to huge sizes and offer mind-boggling performance, especially working with large (read: large) databases.
