Update source of truth, document lessons learned

Before vs. After: The Transformation

❌ Before: Ad-Hoc Approach
  • Manual deployments taking hours
  • Reactive troubleshooting
  • Repeated mistakes
  • Inconsistent processes
  • No documentation
  • High error rates
  • Slow problem resolution
✅ After: Systematic Excellence
  • Automated deployments in minutes
  • Proactive problem prevention
  • Lessons learned and applied
  • Standardized processes
  • Comprehensive documentation
  • Minimal error rates
  • Fast, systematic resolution

Key Lessons & Best Practices

🚀
Launch Template Versioning

Always use Version='$Latest' in Auto Scaling Groups. CloudFormation creates new versions but ASG uses default unless explicitly updated.

❤️
Health Check Independence

Make health endpoints independent of external dependencies like databases for faster failure detection and recovery.

🔍
Systematic Troubleshooting

Follow the process: API working? → JavaScript working? → Launch template version? → Health checks?

📚
Documentation Standards

Maintain comprehensive SOPs, update Golden Backups, and document lessons learned for future reference.

⚡
Cache Management

Always invalidate CloudFront cache after updates. Include cache management in deployment checklist.

🎯
Quality Gates

Use codeReview tool, validate templates, test locally before deployment. Prevention over reaction.
