Ensure the Successful Operation of a Cloud Solution

What this domain really tests

Day-two operations: monitoring and logging (Cloud Monitoring, Cloud Logging), alerting, autoscaling, backups, and cost control. Expect questions on how to detect, diagnose, and remediate operational issues.

Concepts to master

  • Observability: metrics via Cloud Monitoring, logs via Cloud Logging; log sinks route logs to destinations like Cloud Storage or BigQuery.
  • Alerting: alerting policies on metric thresholds; uptime checks for availability.
  • Autoscaling: managed instance groups scale on CPU/utilization or custom metrics; Cloud Run scales on concurrency/requests.
  • Backups and snapshots: persistent disk snapshots, Cloud SQL automated backups and point-in-time recovery.
  • Cost: budgets with alerts, committed use discounts, and rightsizing.

Traps

  1. Confusing logs (events) with metrics (numeric time series) - alerts fire on metrics, not raw logs.
  2. Assuming snapshots are incremental per-disk and region-scoped; cross-region copies need explicit configuration.
  3. Forgetting that a log sink needs a destination and a writer identity with permissions.
  4. Believing budgets stop spending - they only alert.

Rule of thumb

For "detect and notify," use an alerting policy on a metric with a notification channel; for "diagnose after the fact," query logs via Logging or a sink to BigQuery.

Worked example

To alert when a VM's CPU exceeds 80% for 5 minutes: create an alerting policy on the CPU utilization metric with a 5-minute condition and a notification channel.
