Cost Optimization Strategy

Resource Optimization

# Development Environment Costs (~$172/month)
cost_breakdown:
  compute:
    eks_control_plane: "$73/month"
    worker_nodes: "$15/month (t3.medium spot)"
    
  storage:
    rds_database: "$12/month (db.t3.micro)"
    elasticache: "$11/month (cache.t3.micro)"
    ebs_volumes: "$7/month (70GB total)"
    s3_storage: "$1/month (10GB)"
    
  networking:
    nat_gateway: "$32/month"
    load_balancer: "$16/month"
    data_transfer: "$5/month"

# Cost Optimization Features:
optimization_strategies:
  - Spot instances for worker nodes (60-70% savings)
  - Single NAT gateway for development
  - Minimal database instances
  - Lifecycle policies for S3 storage
  - Auto-scaling based on demand
