## Serverless Pricing

### AWS Lambda
```yaml
Requests: $0.20 per 1M requests
Compute:
  - $0.0000166667 per GB-second
  - 128MB, 1s = $0.0000021
  - 1024MB, 1s = $0.0000166667

Free tier: 1M requests, 400K GB-seconds/month

Example: 10M requests, 512MB, 200ms avg
  = 10M * $0.20/1M + 10M * 0.5GB * 0.2s * $0.0000166667
  = $2 + $16.67 = $18.67/month
```

### Azure Functions
```yaml
Consumption Plan:
  - $0.20 per 1M executions
  - $0.000016 per GB-second
  
Premium Plan (always-on):
  - EP1: $0.2065/hour (1 vCPU, 3.5GB)
  - EP2: $0.413/hour (2 vCPU, 7GB)

Free tier: 1M requests, 400K GB-seconds
```
