Production Deployment Checklist

#Introduction

Migrating coomia-dip from development to production involves much more than changing configurations. Production environments require high availability, security hardening, performance tuning, monitoring and alerting, backup and recovery planning. This tutorial provides a comprehensive pre-launch checklist to systematically prepare your production deployment.

#1. Infrastructure

#1.1 Hardware & Resources

#1.2 Network

• Inter-service latency < 1ms (same datacenter)
• gRPC ports (50051-50059) accessible between services
• External API via load balancer (Nginx/Kong)
• TLS certificates configured
• DNS records configured

#2. Security Hardening

#2.1 Authentication & Authorization

• OAuth2/OIDC provider integrated (Keycloak/Auth0/Enterprise AD)
• JWT signing keys generated and securely stored
• API token rotation policy (recommend 90 days)
• RBAC roles defined (SuperAdmin/TenantAdmin/Developer/Viewer)
• Least privilege principle verified

#2.2 Network Security

• TLS 1.3 for all external communication
• mTLS for internal gRPC
• Database ports not externally exposed
• API rate limiting configured
• CORS policies set
• Security headers (HSTS, CSP, X-Frame-Options)

#2.3 Data Security

• Database passwords via secret management (Vault/KMS)
• Sensitive fields encrypted at rest
• Audit logging enabled
• Data classification labels defined

#3. High Availability

#3.1 Control Layer HA

control-Layer:
  replicas: 3
  readinessProbe:
    grpc:
      port: 50051
  livenessProbe:
    grpc:
      port: 50051

#3.2 Database HA

• Doris FE: 3 nodes (1 Leader + 2 Followers)
• Doris BE: 3+ nodes with replication factor 3
• PostgreSQL with primary-replica replication

#3.3 Message Queue HA

• Kafka: 3+ brokers, replication factor 3, min ISR 2

#4. Monitoring & Alerting

#4.1 Core Alerts

groups:
  - name: coomia-dip-alerts
    rules:
      - alert: HighErrorRate
        expr: rate(grpc_server_handled_total{grpc_code!="OK"}[5m]) > 0.01
        for: 5m
      - alert: HighLatency
        expr: histogram_quantile(0.99, rate(grpc_server_handling_seconds_bucket[5m])) > 2
        for: 5m
      - alert: DiskSpaceWarning
        expr: (node_filesystem_avail_bytes / node_filesystem_size_bytes) < 0.2
        for: 10m

#4.2 Business Metrics

• Active users dashboard
• API call volume trends
• Query performance distribution (P50/P95/P99)
• Action execution success rate

#4.3 Log Management

• Structured logging (JSON)
• Log aggregation (ELK/Loki)
• Retention policy (30 days hot + 1 year cold)
• PII masking

#5. Backup & Recovery

#5.1 Backup Strategy

#5.2 Recovery Drills

• Backup integrity verification automated
• Recovery to test environment tested
• RTO and RPO documented and validated

#6. Performance Baseline

#6.1 Targets

#7. Launch Runbook

#7.1 Deployment Flow

1. All tests passing (unit + integration + E2E)
2. Security scan passing (dependency + container image)
3. Configuration review complete (two-person review)
4. Backup strategy verified
5. Monitoring alerts configured and tested
6. Canary deployment plan ready
7. Rollback plan prepared
8. On-call contacts updated

#7.2 Post-Launch Verification

• Core functionality smoke test passed
• Performance metrics within baseline
• No abnormal error logs
• Monitoring dashboards showing normal data
• External system integrations verified

#Summary

This checklist covers six critical areas for coomia-dip production deployment: infrastructure, security hardening, high availability, monitoring and alerting, backup and recovery, and performance baselines. Systematically checking each item before launch significantly reduces production incident risk. Remember: launch is not the end -- it is the beginning of operations.
