# FJ Session cost estimate

## Payload Size
- According to httparchive the average web page size in 2017 was 3 MB
- Assume that that size is increased, so maybe ce can say it is 3.5 MB
- Assume that we’ll need about two page loads to catch an issue on a website
- Assume that we have 3-4 screenshots which are about 200 KB
- Assume average session size is 8 MB
- Here's the usage of CCC:

## Cost Estimate

### Asume that we have 1000000 submissions per month
- S3 Storage
    - ~8 TB = $184 
- S3 Transfer
    - Storing
        - $0.005 per 1,000 PUT, COPY, POST, or LIST requests
        - Assume one log will have about 1M PUT requests
        - Cost: (1M / 1000) * 0.005 = $2
    - Reading
        - $0.004 per 10,000 GET and all other requests
        - Assume we have 5 requests per log 
        - Cost: (1M / 10000) * 5 * 0.004 = $2
- CloudFront
    - $0.085 per GB - first 10 TB / month data transfer out
    - $0.080 per GB - next 40 TB / month data transfer out
    - Assume we have 3 requests per log
    - ~8 TB * 3 = 24 TB 
    - Cost: (First 10 TB) $870 + (Next 14 TB) 1147 = ~ $2000

### Total cost
- For 1M submissions ~ $2200
