Analyzing Architecture Tradeoffs
summary
Claim: switching to gRPC cuts roundtrip latency from 110ms to 7ms, but introduces tight coupling and worse maintainability; using a single payment service speeds internal consistency but raises testing, deployment and rollback risk compared with separate services; choosing async vs sync for credit‑card onboarding becomes a business choice—accept submissions always or guarantee process start—boiling down to CAP‑like consistency vs availability; messaging design trades producer complexity for topic extensibility vs queue control.
