Whenever you're ready, walk me through how you'd approach this.
Explain a time you identified a system bottleneck and the steps you took to resolve it in a cloud environment.
Describe how you separated symptoms from the actual constraint, which telemetry or profiling tools you used, how you validated the root cause, and how you confirmed the fix. Keep the answer focused on your investigation, remediation, and prevention steps. Scope: cloud-hosted systems, observability, performance diagnosis, and capacity or architecture decisions.
