Fake Bank APP

A (dead) simple RPC based banking application.

This app was created for educational purposes to test RPC capabilities in Node and is not suitable for production environments. Many things should be designed differently. For instance, this app was does not scale properly. Each exchange points to a queue that is consumed by only one consumer. For this architecture to be more effective, we should dynamically add more consumers when we find that a particular queue gets very big. This is a basic load balancing solution that could increase tasks resolving time.
