• State stored remotely (GCS)

• No manual changes

• Plan before apply

• Code review for changes

Security

• Workload Identity (no key files)

• Least privilege IAM

• Network policies

• Pod Security Standards

Monitoring

• All services have health checks

• Key metrics dashboards

• Alerting for critical issues

• Log aggregation

Templates

Terraform Module Structure

Checklist

Before Deploying

• Terraform plan reviewed

• Security scan passed

• Tests passing

• Rollback plan ready

• Monitoring configured

Infrastructure Quality

• All resources tagged

• Secrets in Secret Manager

• Network policies in place

• Health checks configured

Anti-Patterns to Avoid

• ClickOps: Never configure manually

• Snowflake Servers: Use immutable infrastructure

• No Rollback Plan: Always have escape route

• Hardcoded Secrets: Use Secret Manager

• No Monitoring: Observe everything
