Per-service cost breakdown, before/after optimization comparison, checklist:
Verify the following resources are NOT created:
| Prohibited Resource | Monthly Cost | Alternative |
|---|---|---|
| NAT Gateway | ~$33 | Fargate Public IP |
| ALB/ELB | ~$18-25 | API Gateway |
| Interface Endpoint | ~$7/each | Public IP for public endpoint access |
| DynamoDB Provisioned | Variable | PAY_PER_REQUEST |
| Lambda in VPC | Requires NAT | Deploy outside VPC |
| Category | Target |
|---|---|
| Within Free Tier | ~$0.23/month |
| After Free Tier | ~$1.07/month |
| Maximum allowed | Under $10/month |
See cost-optimization.md §9 for full Lambda cost analysis.
| Resource | Cost Model | Notes |
|---|---|---|
| Lambda invocations | Per-request | 1M requests/month free tier |
| Lambda duration | Per GB-second | 400K GB-seconds/month free tier |
| Lambda container image | ECR storage | ~$0.10/GB/month after 500MB free |
| No Fargate idle cost | — | Lambda scales to zero automatically |
Key advantage: Lambda charges only for actual execution time — no idle Fargate cost when no users are active. For low-traffic usage, Lambda runtime cost approaches $0/month within free tier.
