# Fiddler S3
## Users and sessions
Monthly users - 50,000
Monthly sessions per user - 10
Monthly shares per session - 10
Monthly sessions shares in total - 50,000 x 10 x 10 = 5,000,000
## S3 Standard storage
Monthly snapshots + versions = Monthly sessions shares in total = 5,000,000
Average snapshot size = 0.5 KB
Monthly storage = 5,000,000 * 0.5 KB = 2,500 GB
### PUT, COPY, POST, LIST requests to S3 Standard
Monthly put/post should be equal to monthly snapshot shares - 5,000,000
### GET, SELECT, and all other requests from S3 Standard
Having in mind that every start of fiddler downloads the snapshots plus every change to a snapshots is downloaded in the open clients we assume that a user will get about 50 snapshots downloads per month which makes 5,000,000 x 50 = 250,000,000 get requests
### Data returned by S3 Select

### Data scanned by S3 Select

## Data Transfer
### Inbound Data Transfer
These are free, so we don't need to estimate
### Outbound Data Transfer
The number of get s3 GET requests above multiplied by the average snapshot size(or delta) = 250,000,000 * 0.2 KB = 50 TB
