Pillar 1: Operational Excellence
| Principle |
DevOps Implementation |
| Automate everything |
CI/CD pipelines, IaC, automated testing |
| Monitor proactively |
Cloud Monitoring, alerting, SLOs |
| Manage incidents well |
Runbooks, on-call rotations, postmortems |
| Continuous improvement |
Regular reviews, chaos engineering |
| Document operations |
Living documentation, architecture decision records |
Pillar 2: Security, Privacy & Compliance
| Principle |
DevOps Implementation |
| Defense in depth |
VPC Service Controls, IAM, encryption |
| Least privilege |
Service accounts with minimal roles |
| Shift security left |
Binary Authorization, vulnerability scanning |
| Centralize audit |
Cloud Audit Logs, SIEM integration |
| Automate compliance |
Policy as Code, org policies |
Pillar 3: Reliability
| Principle |
DevOps Implementation |
| Design for failure |
Multi-zone/region deployments, health checks |
| Set SLOs |
Define and measure availability targets |
| Manage error budgets |
Balance velocity and reliability |
| Automate recovery |
Auto-healing MIGs, self-healing GKE pods |
| Test resilience |
Chaos engineering, disaster recovery drills |
Pillar 4: Cost Optimization
| Principle |
DevOps Implementation |
| Right-size resources |
Recommender API, custom machine types |
| Use commitments |
CUDs for predictable workloads |
| Leverage Spot |
Spot VMs for batch and CI/CD |
| Optimize storage |
Lifecycle policies, storage classes |
| Monitor costs |
BigQuery billing export, budgets |
| Principle |
DevOps Implementation |
| Distribute globally |
Cloud CDN, multi-region services |
| Cache strategically |
Memorystore, CDN, application caching |
| Scale automatically |
MIG autoscaling, GKE HPA, Cloud Run |
| Profile and optimize |
Cloud Trace, Cloud Profiler |
| Choose right services |
Serverless vs VMs vs containers |
