Key Concepts
- SLI: metric measuring service performance (latency, error rate, throughput).
- SLO: target for an SLI (e.g., 99.9% availability).
- Error budget: 100% − SLO = allowed unreliability.
- Toil: manual, repetitive, automatable operational work.
- Blameless post-mortem: focus on what happened, not who caused it.
- Golden signals: latency, traffic, errors, saturation.

Google Cloud Service Quick Reference
GCP organises services around Compute (GCE, GKE, Cloud Run, App Engine, Cloud Functions), Storage (Cloud Storage, Persistent Disk, Filestore), Databases (Cloud SQL, Spanner, Firestore, Bigtable, BigQuery), and Networking (VPC, Cloud Load Balancing, Cloud CDN, Cloud Interconnect). Knowing which service fits each use case is essential for passing GCP exams.
