Software Architecture Stories

This document discusses software architecture patterns and principles. It describes three stories that illustrate techniques for crafting software architectures. The first story talks about using layers to separate levels of abstraction and isolate points where components interact. The second story discusses how to loosely couple components through events and messages. It also addresses separating transient and stateful components. The third story shows how to use explicit scheduling to conveniently execute tasks asynchronously in a controlled way. Overall, the document advocates for separating architectures into layers, isolating failure points, distinguishing state, and being explicit rather than relying on magic.
