Modern systems don’t wait. They react.

event → λ

Trigger. Flow. Execution.

The event → λ pattern represents the core of event-driven architecture — systems that execute only when something happens.

• event — a trigger: file upload, API request, message, or scheduled action
• → — the execution flow
• λ (lambda) — the function that runs on demand

No always-on servers.
No idle compute.
Just execution when it matters.

This model defines modern serverless systems: scalable, reactive, and efficient by design.

For engineers building distributed systems, event → λ is more than a pattern — it’s an architectural principle.

Reactive. Stateless. On-demand.

Because great systems don’t run constantly — they respond.

event → λ
