How would you automate canary deployment and what metrics decide rollback?
This tests progressive delivery maturity. Strong answers cover traffic splitting (10% to 100%), automated 5-10 minute health gates, and rollback triggers like error rate and p99 latency.
This tests whether you can design safe, automated progressive delivery with real rollback criteria. A strong answer outlines traffic splitting stages (10/90, 25/75, 50/50), automated analysis windows of 5-10 minutes per stage, and rollback triggers tied to error rate, p99 latency, and throughput deviation against the stable baseline. Mention readiness and liveness probes as early signals. Red flag: proposing manual promotion without automated gates or ignoring baseline comparison.
