Regarding communication between nodes/apps/plugins -for example in C++, C, GO Python, Java, JS, LabView, Matlab I really recommend DDS - real time communication, securing QoS and security. DDS is a communication standard in Robot Operating System 2 (ROS2) also and implementation of this standard is frequently used by many companies across the world (this comment is a bit away from the core article but you Erik discuss a bit about CORBA). Probably the the best implementation/advanced has been performed by RTI.
