""In an interview, I explain how we designed actionable, symptom-based alerting using the Four Golden Signals. The interviewer is testing: Proactive vs reactive monitoring.. I structure my answer around systematic triage first, root cause analysis second, and permanent remediation third.""

Production Solution & Architecture
Synthetic Monitoring is simulating user traffic to proactively test your systems from the outside. Instead of waiting for real customers to log in and report that the "Add to Cart" button is broken, you deploy a headless browser script (using tools like Datadog Synthetics, Cypress, or Selenium) running from various global AWS regions. It logs in, adds an item, and checks out every 5 minutes 24/7. If the workflow fails or takes too long, it triggers an alert before real users are severely impacted.
