What a small SaaS actually costs to run on AWS, measured rather than estimated

Every "cloud costs" post I read is either a horror story about a $40k bill or a vendor telling you it's basically free. Here's an actual measured number for something small. One web app, one managed Postgres, dev environment, light traffic, us-east-1, list prices: Load balancer: $17.01 Public IPv4: $14.60 Compute: $5.41 Data out: $1.80 Logs/metrics: $0.06 $38.88/month, and the application is $5.41 of it. Production with a real database is meaningfully more, but the shape holds: at

痛点：小型SaaS在AWS上即使应用本身只花几美元，也会被负载均衡、公网IP等固定入口成本拖到约35美元/月，且多环境成本近似线性增长，独立开发者缺少简单透明的优化工具。

目标用户：在AWS上运行小型SaaS或side project的独立开发者、早期创业团队

证据：the cheapest possible AWS app is not free, it's about $35, and it's $35 whether you have 1 user or 100. Share one load balancer across environments, routed by hostname. Saves ~$17 per extra environment.

变现：免费成本计算器引流，付费提供Terraform/CDK优化模板、自动化多环境共享ALB与定时缩容脚本、按月订阅的AWS成本审计报告或一次性配置服务

MVP：2周内做一个Web计算器：输入AWS资源/环境数量/流量，按us-east-1 list price估算月费，并生成共享ALB、非生产环境定时缩容的Terraform片段与 checklist。

竞品：AWS Cost Explorer、Infracost、Vantage、CloudHealth、CloudZero

摘要：帖子实测一个小型SaaS在AWS us-east-1的月成本为38.88美元，其中应用计算仅5.41美元，负载均衡和公网IPv4占约31.61美元。作者指出最小可行AWS应用约35美元/月，且多环境成本几乎线性增长，并建议共享负载均衡、非生产环境缩容到零。这是一个真实的成本优化痛点，但原帖没有明确付费意愿数据。
