🏗️ Infrastructure Created:
• ECS Fargate cluster with auto-scaling
• Application Load Balancer with health checks
• Blue/Green target groups for zero-downtime deployment
• ECR repository with image scanning
• CloudWatch monitoring and alarms
• IAM roles with least-privilege access

💰 Estimated Cost: ~\$18-37/month

🚀 What's Working:
• Containerized Flask microservice
• Automatic health checks
• Blue/Green deployment capability
• CloudWatch monitoring
• Container insights

🌐 Access Your Application:
Check the archived terraform-outputs.json for URLs

📋 Next Steps:
• Phase 3: Advanced monitoring and alerting
• Phase 4: CI/CD automation improvements
• Consider setting up custom domain and SSL

📊 Monitoring: Check CloudWatch for metrics and logs
