Communication between instances
Instances, for the most part, run on separate computers. The beauty of nio pub-sub functionality is that users don’t need to think in those terms within a nio system—simply publish and subscribe as if the instances were one-in-the-same. The lines between the distinct hardware in a system fade into the background.
For most users, Pubkeeper is a silent communications enabler. Advanced users may dive deeper into functionality and configuration for their systems.
