Google Kubernetes Engine is a managed Kubernetes platform that lets teams run containers on Google Cloud without wrangling control planes. You get automatic control-plane upgrades and repairs, multi-zone resilience, and deep integration with Google Cloud services.

Core building blocks
- Clusters & node pools: Start with a regional cluster for HA. Use node pools to separate workloads (e.g., web, batch, GPU).
- Workload objects: Package apps as containers, then deploy with Deployments, expose with Services, and route traffic with Ingress.
- Autoscaling & releases: Right-size with requests/limits, HPA for pods, Cluster Autoscaler for nodes. Use rolling updates and instant rollbacks.
Networking essentials
- Choose Autopilot for opinionated security and cost efficiency or Standard for granular control.
- Map traffic via HTTP(S) Load Balancing; prefer internal load balancers for east-west traffic. Keep namespaces, network policies, and service accounts scoped by environment.
Security from day one
- Enable Workload Identity to map service accounts to IAM — no node-wide keys.
- Apply Pod Security Standards, minimal RBAC, and store secrets in Secret Manager.
- Regularly scan images (Artifact Registry) and pin base images.
Operations that scale
- Ship logs/metrics to Cloud Logging/Monitoring; build SLOs and alerts early.
- Use GitOps (Cloud Build/Cloud Deploy or Argo CD) to promote between dev → staging → prod.
- Watch spend with labels, GKE cost allocation, and autoscaling policies.

Starter checklist
- Pick Autopilot vs. Standard.
- Create a regional cluster + dedicated node pools.
- Wire CI/CD and image scanning.
- Enforce identity, RBAC, and network policy.
- Define SLOs, dashboards, and alerts.
