Site Reliability & Observability Challenges
Site Reliability & Observability challenges put you on the hook for keeping production healthy. You'll build the fundamentals — Application Monitoring, Dashboard Reading, and Performance Analysis — and instrument services with OpenTelemetry instrumentation, Prometheus & Grafana, then define what "healthy" means through Service Level Objectives and SLO / SLI definition.
From there you'll handle the harder edges — Incident command, On-call runbooks, Multi-region failover, and Chaos engineering — the way reliability teams actually operate under pressure. Each challenge you solve earns a verified credential you can share with recruiters.
