# 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

We don't do S3 scans but direct get by key

### Data scanned by S3 Select

We don't do S3 scans but direct get by key

## 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
