Sample Answer
When a public API I owned spiked from 200ms to 1.2s under peak (10k RPS), I first reproduced the load in a staging cluster and collected distributed traces and real CPU/memory profiles. Traces showed long DB queries and frequent GC pauses from oversized JSON unmarshalling. I prioritized fixes: 1) add a read replica pool and offload heavy reads (reduced DB p99 by ~60%), 2) introduce request-level caching with Redis for hot endpoints (cache hit ~45%), and 3) replace blocking JSON parsing with a streaming parser and connection pooling in the HTTP client, cutting CPU and latency. I also added circuit breakers and rate limiting so failures didn’t amplify, and monitored throughput and error budget until stable.
