As Operational Technologies (OT) like embedded devices, control and monitoring systems are increasingly integrated with Information Technology (IT) systems running in the back office, interaction patterns between systems are becoming more complex and diverse. Publish-Subscribe is the most commonly used messaging pattern for OT systems. It provides the real-time information access, scalability, and loose coupling required for integration of these types of systems. IT and OT integration, however, commonly requires messaging patterns that provide stronger end-to-end properties, such as Guaranteed Delivery, Request-Reply, and (load-balancing) Queues. RTI is greatly enhancing its infrastructure software with new messaging patterns that combine the performance, scalability, and reliability needed by OT systems with the integration and flexible messaging capabilities of IT systems.
