Serverless architectures refer to applications that significantly depend on third-party services (knows as Backend as a Service or "BaaS") or on custom code that's run in ephemeral containers (Function as a Service or "FaaS"). By using these ideas, and by moving much behavior to the front end, such architectures remove the need for the traditional 'always on' server system sitting behind an application.

Patterns for mapping intents to actions in event-driven architectures
It seems to be common sense that hiding commands (i.e. triggers for actions such as calling a serverless function) in events is an antipattern. Applying the event pattern for user interactions (event: "user has pressed button X") seems forced and…
