queue → λ — Async worker pattern
Not every task needs to happen immediately.
queue → λ
Decouple the work. Process it later.
In modern backend systems, this pattern defines asynchronous execution.
The queue stores incoming tasks — messages, jobs, events.
λ (lambda) consumes and processes them independently.
No blocking.
No bottlenecks.
Just controlled flow.
This is how systems scale:
distribute the load, isolate execution, and let infrastructure handle growth.
For engineers building distributed systems, queue → λ is more than a pattern — it’s a design principle.
Decoupled. Scalable. Resilient.
Because good systems don’t block — they queue.
