Audio N/AQuick interview answer
At 10× traffic, Artifact Promotion (Build Once) usually hits queueing and CPU/I/O saturation first — mitigate with concurrency limits, batching, caching, and offloading. At Junior depth: start with the problem, then mechanism, then a short example. Build a versioned image/package once in CI; promote the same digest through staging→prod.
Detailed answer
At 10× traffic for Artifact Promotion (Build Once): 1) Bottleneck shifts from “works on my laptop” to queue delay and resource saturation. 2) Protect the loop/path: timeouts, bulkheads, backpressure, worker offload for CPU work. 3) Scale out carefully: sticky vs stateless, connection pools, cache hit ratio. 4) Prove with load tests that p99 stays inside SLO. Example to cite: CI pushes ghcr.io/app:sha-abc; staging and prod both pull sha-abc. Parent context: At Junior depth: start with the problem, then mechanism, then a short example.
