Design microservice boundaries, API contracts, and async patterns

Building scalable systems where services fail independently without cascade.

• · Domain model, service responsibilities, latency/consistency requirements

• · Service boundaries, OpenAPI/gRPC specs, event schemas, deployment topology

• · Domain-driven design
• · Conway's law awareness
• · Async/event-driven patterns

• · Chatty RPC (too many hops)
• · Shared database (lost isolation)
• · Saga without idempotency (duplicate charges)

• · Tibsfox, stable 2026-04-12
