Benefits

  • Zero downtime deployments
  • Easy rollback
  • Reduced risk

  1. Automation

    • Use CI/CD pipelines
    • Automate testing
    • Infrastructure as Code
  2. Monitoring

    • Health checks
    • Performance metrics
    • Error tracking
  3. Rollback Plan

    • Version control
    • Database migrations
    • State management
