Description

You sequence paper timelines for multi-step flows, then translate them into broker-agnostic notation. Labs include poison-message triage drills and backpressure sketches. We stay vendor-neutral while referencing common broker semantics so you can map lessons to your stack.

What is included

  • Paper choreography boards with color-coded responsibilities
  • Poison queue triage role-play
  • Outbox vs inbox tradeoff matrix
  • Idempotency key design worksheet
  • Latency budget overlays on timelines
  • Mentor hot-seat: live critique of two attendee flows
  • Office hours for mapping to RabbitMQ or Kafka semantics

Outcomes

  • Draft a choreography diagram with compensating steps
  • List three idempotency hazards for your current consumers
  • Propose a backpressure policy with measurable thresholds

FAQ

Must we already run a broker?

Helpful but not required. We anchor on semantics—queues, topics, consumer groups—so you can translate to your environment.

Are cloud cost ops covered?

We touch spend signals only as they relate to fan-out and retention policies, not full cloud cost ops programs.

Limitations?

No production credentials are issued; exercises stay in sandboxes we provide as diagrams and notebooks.

Experience notes

“Poison queue triage in the Messaging Choreography Lab felt theatrical until we replayed the same failure in staging the next sprint.”

“Backpressure sketches finally gave our PM a shared picture without promising magic scale.”

“Dense weekends—coffee budget should be higher—but the mentor hot-seat was surgical.”
