Coupling

Good platforms emphasize loose coupling where one part of the system can change without affecting another.

Not abstractions for the sake of abstraction.

But rather well-thought-out data structures and patterns.

A message bus like NATS is an excellent way to decouple a program. One part of the system publishes information, and any other interested part can subscribe.

But for this to work, you must have simple and flexible data structures that don't change often. Otherwise, your system is now tightly coupled again.

Simple data structures and messaging -- a sane way to scale YOUR Platform.
