📚 Key Lessons Showcased

1. Launch Template Versioning (Project 5 Breakthrough) - CloudFormation creates new versions but ASG uses default - Always specify Version='$Latest' in Auto Scaling Groups - Small details can cause major deployment issues 2. Health Check Independence - Make health endpoints independent of external dependencies - Faster failure detection and recovery - Improved system resilience 3. Systematic Troubleshooting Process - API working? → JavaScript working? → Launch template version? - Methodical approaches solve problems faster - Documentation of troubleshooting steps 4. Documentation Standards - Maintain comprehensive SOPs - Update Golden Backups regularly - Document lessons learned for future reference 5. Cache Management Best Practices - Always invalidate CloudFront cache after updates - Include cache management in deployment checklist - Prevent stale content issues 6. Quality Gates Implementation - Use codeReview tool before deployment - Validate templates and test locally - Prevention over reaction approach
