You Keep Using That Word: Asynchronous And Interprocess Comms (Remote)

Argues that "asynchronous" is ambiguous and unusable, replacing it with concrete choices: request–response vs event-driven interactions, client-side non-blocking clients for parallel calls (example: award-points 50ms + upgrade-sub 150ms sums to 200ms but runs in ~150ms when parallelized), or broker-backed communication for temporal decoupling with guaranteed delivery, retries and idempotency. Calls out VM SLA realities (no per‑VM uptime guarantee) and recommends specifying exact failure and latency behaviors instead of waving the word asynchronous.
