What it shows

Sync HTTP/gRPC introduces tight coupling and cascading downstream timeouts.
Async event buses decouple services but require handling partial failures.
Transactional outbox ensures database writes and event publishing match.

The takeaway

Default to asynchronous event messaging; use synchronous RPC only when data is needed now.
