Twelve-Factor Application: Separate Build and Run Stages

In Twelve-Factor apps, the build process prepares the application for deployment, while the run stage focuses on its execution.

CAP: Multiple Event Handlers

CAP event handling allows you to attach multiple functions (event handlers) to different stages of an event's lifecycle, enabling a chain of actions based on the event.

Twelve-Factor Statelessness

Twelve-Factor Microservices emphasizes statelessness, meaning each request is processed without relying on prior states. This ensures consistent results across multiple executions.
