Cost Optimization

AWS Costs​

With EC2 Pool (10 instances, t3.small)​

  • EC2 instances: ~$50-100/month (when running)
  • Lambda functions: ~$1-5/month
  • Storage (S3, DynamoDB): ~$1-3/month
  • CloudFront: ~$1-2/month
  • Total: ~$53-110/month

Lambda-Only Deployment​

  • Lambda functions: ~$1-5/month
  • Storage: ~$1-3/month
  • CloudFront: ~$1-2/month
  • Total: ~$3-10/month

Cost-Saving Tips​

  1. Use smaller instance pool: Start with 5-10 instances
  2. Destroy when not in use: Use --destroy between classes
  3. Optimize instance types: Use t3.micro for development, t3.small for production
  4. Monitor usage: Check AWS Cost Explorer regularly
  5. Enable auto-stop: Instances automatically stop after idle timeout
